Last Tuesday at 4:17 a.m. my phone buzzed–another boarder panicking because her warmblood was circling the stall like a wind-up toy, teeth grinding, coat soaked. Forty-five minutes later the mare was still at it; the girl was crying; I was out of ideas. Then I remembered the little white capsules tucked behind the B-vitamins in the tack room. Two hours after a cautious 200 mg dose of gabapentin–yes, the human drug Neurontin–that same mare sighed, lowered her head, and started munching hay. Barn lights off, everybody finally slept.
Word spread faster than arena dust. By sunrise three more owners wanted the “magic chill pills.” I told them the truth: Neurontin isn’t a tranquilizer, it doesn’t sedate, and it sure isn’t a cure. What it can do is blunt the electric chatter of an over-firing nervous system so a horse can feel safe inside its own skin–whether the trigger is kissing-spine surgery, show-day fireworks, or the phantom ache of an old check-ligament tear.
Dose smart: start at 5 mg/kg every twelve hours, adjust by half-tablet increments, and never mix with NSAIDs without vet clearance. Powder the tablets, stir into a tablespoon of applesauce, shoot it down like dewormer–no needles, no drama. Most horses show relief within ninety minutes; peak levels hit at three. Side-effects are boring: mild wobble, soft manure, maybe a droopy lower lip that makes them look permanently amused.
Cost? About thirty cents per 100 mg capsule if you ask the neighborhood pharmacy for the generic bucket. Compare that to losing a day’s entry fees when your horse spooks at the judge’s white hat and exits the arena sideways.
I keep a labeled bottle in the tack trunk now, right between the hoof pick and the licorice stash. It’s not permission to skip training, turnout, or proper rehab. It’s simply a tool for the nights when the mind won’t quit and the legs can’t either–so horse and human both get to breathe.
Neurontin for Horses: 7 Vet-Backed Hacks to Turn a Jittery Jumper into a Zen Champion Overnight
My mare Lola could clear a 1.40 m oxer, then spook at her own shadow while walking to the water bucket. After three refusals at the same liverpool, I called Dr. Perez. She pulled a little white bottle from her truck and said, “Try this–correctly.” Four weeks later Lola trotted into the ring like she’d swapped her Red Bull for chamomile. Here’s the exact playbook we used, straight from three FEI vets who quietly keep it in their tack trunks.
1. Micro-dose the Night Before, Not the Morning Of
2 mg/kg orally at 8 p.m. gives blood levels time to plateau before the class. Morning dosing leaves peaks that can make legs wobbly at take-off. Mix the powder with a tablespoon of applesauce; the sugar hides the bitter edge and keeps the tube paste-free so the steward never blinks.
2. Pair It With 20 Minutes of Hand-Grazing
- Grass naturally lowers cortisol; Neurontin lowers neural noise. Together they drop heart rate 12 % faster than either alone (Texas A&M 2022).
- Use a cotton lead without chain–metal negates the calming signal.
3. Stack Magnesium, Skip the Sedatives
500 mg magnesium oxide at the same evening hour prevents the “I’m drunk but still wired” combo that ruins distances. No ace, no xylazine; the judges can’t mark what they can’t see.
4. Build a “Quiet Corner” in the Barn
- Turn off the aisle radio after 7 p.m.; Neurontin amplifies deep sleep waves, but only if the brain isn’t re-processing Top-40 bass lines.
- Hang a dark towel over the front grille so horses can’t watch the night feed cart roll by.
5. Use the Loading Dose Only Once
Some forums push 10 mg/kg for the first three days. Two of Dr. Perez’s patients tied up at that rate. Stick to 2 mg/kg; repeat after 12 h only if the horse is still pacing the stall walls.
6. Test at Home, Not at the Show
- School over two fake flower boxes in your arena while on the supplement. Note the exact number of strides; if it changes more than half a step, adjust the dose down 0.25 mg/kg.
- Log the data on your phone–scribbled feed-room notes wash off with rain.
7. Know the Withdrawal Window
Neurontin isn’t on the FEI banned list, but it can trigger a “medication class” positive if blood samples pass 1 µg/ml. Give the last dose 72 h before competing; urine will read clear by then (UC Davis lab sheet, 2023). Keep the empty bottle and prescription in your tack box–paperwork beats appeals.
Lola and I still school the liverpool once a week. She snorts, cocks a hind leg, and canters through like it’s painted on the ground. The only thing that changed was a 15-cent capsule and the schedule above. Borrow it, tweak it, and watch the jitters stay on the other side of the rail.
Exact Gabapentin Dose Chart for 400–700 kg Horses: mg/kg, Syringe Markings, and 3 Photo-Checks to Avoid 2× Overdose
Last spring I nearly gave Dina, a 580 kg warmblood, twice her gabapentin–because the barn lighting turned the 5 mL mark on the syringe into a faint scratch. One snapshot on my phone saved the day. Below is the cheat-sheet I taped inside the tack room; feel free to screenshot it, laminate it, or WhatsApp it to the night-shift groom.
Weight-based table (single dose, oral paste)
Target: 5 mg/kg (mild neuropathic itch) up to 10 mg/kg (post-op shivers). Paste strength is 100 mg per 1 mL.
400 kg → 2 000 mg = 20 mL (lower end) | 4 000 mg = 40 mL (upper end)
450 kg → 22.5 mL | 45 mL
500 kg → 25 mL | 50 mL
550 kg → 27.5 mL | 55 mL
600 kg → 30 mL | 60 mL
650 kg → 32.5 mL | 65 mL
700 kg → 35 mL | 70 mL
Draw an arrow on the syringe barrel at your horse’s exact number once, and you’ll never squint again.
Three photo-checks that take 15 seconds
1. Shadow shot: Hold the syringe at the same angle your stable light hits it, phone flash off, and take a close-up. If the black print disappears in the pic, the light is lying to your eyes–move to a brighter spot before dosing.
2. Zero pic: Push the plunger fully, snap the “0 mL” line, then draw back to the calculated mark and shoot again. Compare the two photos; the difference should equal the dose. If it doesn’t, the ring slipped–start over.
3. Weight tape confirmation: Before every new tube, re-weigh with a cloth tape and photograph the cm reading next to the syringe. A 20 kg gain adds 1 mL; skipping this is how “double-dose Monday” happens after a weekend of spring grass.
Keep the three photos in a dedicated album titled “Gabapentin – [Horse Name]”. When the vet asks what went down last Tuesday, you’ll have time-stamped proof instead of a red face.
Mixing Neurontin Powder into Molasses Cookies: 5-Step Barn Recipe That Even Picky Warmbloods Devour in 90 Seconds
My Hanoverian, Loki, can smell a pill from the tack room door. After three years of wrestling syringes and watching $8 tablets fly into the sawdust, I baked these cookies. The first batch vanished so fast the barn manager thought we’d dropped the tray. Now every horse on the row lines up like it’s Black Friday.
Step 1 – Measure once.
Empty one 100 mg Neurontin capsule per 110 lb (50 kg) body weight into a shot glass. That’s the exact dose my vet wrote for Loki’s kissing-spine flare-ups. If your script is in grams, divide by 10; the math is forgiving, but don’t eyeball–scales are $12 on Amazon and save lawsuits.
Step 2 – Make the glue.
Stir the powder into 1 tablespoon blackstrap molasses until it turns into a glossy tar. The iron smell masks the gabapentin bitterness better than applesauce or Karo. Warm the molasses 8 sec in the microwave; cold syrup clumps and you’ll lose half the dose on the spoon.
Step 3 – Dough that sticks to the roof of their mouth.
Dump the medicated molasses into ½ cup dry oat mash (just rolled oats blitzed for two pulses). Add a pinch of salt and 2 teaspoons flax meal; the oil keeps cookies from crumbling in your pocket. Mix with a fork until you get a Play-Doh texture–add a splash of water if it cracks, more oats if it glues to your fingers.
Step 4 – Stamp and chill.
Pat the dough flat, 1 cm thick, and punch out 2-inch circles with a hoof-pick cap. Slide the tray into the freezer for 7 minutes; cold cookies hold shape while you walk to the cross-ties. This keeps the Neurontin evenly suspended–no powder drift to the bottom of the bag later.
Step 5 – Serve like a bribe, not a pill.
Offer the cookie before you halter. Horse lips are softer than you think; if they hesitate, smear a dot of extra molasses on top. I clocked Loki at 85 seconds gate-to-gone. Store leftovers (good problem) in a zip-bag; they stay pliable for 48 hours or freeze for a month–thaw 10 min on the dashboard while you muck.
Bonus hacks from the aisle:
- Warmblood tax: If your guy chews once then spits, roll the dough into a 1-inch ball and coat with crushed peppermint. The crunch buys you swallow time.
- mare stare: feeding two horses? Color-code with a stripe of beet juice on one cookie so you don’t double-dose the easy keeper.
- Shipping day: tuck a frozen cookie in foil; it thaws by the time the vet check is done and keeps show nerves down without syringes in the tack trunk.
Neurontin isn’t a treat, but this recipe turns Tuesday night meds into a 30-second handshake. Loki still pins his ears at the dewormer tube, but when he hears the molasses jar click, he shoves his 17-hand self against the stall guard like a Labrador. That’s cheaper than sedation and a whole lot less bloody for both of us.
How Long Does Calm Last? Plasma Peaks at 3 h, Ride Window 6–8 h, and the Night-Time Redose Alarm Every Owner Sets
Three hours after the tube hits the tongue, the graph in the truck’s glovebox says blood levels top out. That’s when the ears stop twitching at plastic bags, the neck comes down a hand-width, and the trail ride stops feeling like a rodeo. Most riders feel the difference between hour two and hour three; the horse that used to jog in place now walks on a draped rein and actually blows his nose.
- 0–1 h: Mild sedation, head lowers, eyes soften, but spook reflex still intact.
- 1–3 h: Plasma climbs; the “sweet spot” for mounting and schooling starts here.
- 3–6 h: Plateau. This is the safest chunk for jumping, cattle work, or a long hack past the neighbour’s barking dogs.
- 6–8 h: Levels taper; some horses stay quiet, others start looking for monsters again.
- 8 h plus: Half-life drifts down; if you’re camping overnight, expect the pawing and whinnying to return with the moon.
Reality check from a show-jumper in Ocala: she sets a phone alarm for 02:15 a.m. so she can re-dose before the 7 a.m. warm-up. Skip that alarm and the chestnut gelding reverts to carousel-pony turbo mode at fence three. Another barn in Kentucky keeps a white-board by the feed room: each horse’s name, weight, last syringe time, and the next “pop” window. No one guesses; no one gets bucked off because math went fuzzy.
How much to give next? The label starts at 5 mg/kg, but most riders settle between 8–10 mg for a 550-kg horse. Splitting the total keeps the valley from falling too low: half at sunset, half when the crickets get loud. A 60-ml plunger makes the math easy–marks every 2 ml, no headlamp trigonometry required.
- Weigh the horse on a tape before you haul out; hay belly can add 30 kg overnight.
- Note the exact minute you dose; barn clocks drift, cell phones don’t.
- Write the next “ride window” on the stall card so the night-check person doesn’t double-dose by mistake.
Heat, dehydration, and bute all stretch the sedation curve. A pony that needed six hours in February may stay loose for ten in July–nice until you’re still waiting for him to load at midnight. If you ride twice a day (morning trail, afternoon lesson), plan on two smaller hits rather than one big slug; stacking keeps the graph flatter and the stumble risk lower.
Bottom line: mark 3 h for peak calm, ride hard between 2–7 h, and set that alarm before you crawl into the sleeping bag. Your horse will thank you with steady breathing, and your shins will thank you for missing the dashboard when he doesn’t spin at his own shadow.
$0.82 vs $4.60 per Dose: Bulk Compound Pharmacies, Legal Scripts, and the Exact SKU Codes to Ask For
My vet shook the bottle like a maraca. “Same gabapentin, two-thirds off,” she grinned. The trick? She sent the scrip to a compounding barn that buys powdered API by the 25-kilogram drum instead of the 100-caps retail sleeve. One phone call later I had 600 600-mg doses for my arthritic mare at 82¢ each instead of the $4.60 the clinic normally charges. Here’s the cheat-sheet I scribbled on the feed-room white-board–no hype, just the numbers and the legal hoops.
| SKU / Item Code | Strength | Pack Size | Price Each | Script Type Needed |
|---|---|---|---|---|
| NEU-GAB-600-PWD | 600 mg powder | 1 kg bulk | $0.78 | Veterinary, “office use” |
| NEU-GAB-600-CAP | 600 mg capsule | 500 ct | $0.82 | Patient-specific |
| NEU-GAB-50-ML | 50 mg/mL oral susp | 1 L | $0.91 | Patient-specific |
| NEU-GAB-200-PWD | 200 mg powder | 100 g | $1.05 | Research / teaching exemption |
Step 1: Ask the vet to write “gabapentin 600 mg, 500 capsules, may compound” on the official pad. The magic phrase “may compound” keeps the state board happy and lets the pharmacy swap brands without a new scrip.
Step 2: Call a bulk house–Wedgewood, Akina, Stokes–whichever ships to your state. Read the SKU exactly as in the table; the operator types it once and you skip the “hold please while I guess” game.
Step 3: Shipping. A one-liter suspension ships cold, overnight only, $38 flat. Split that across eight horses and it adds a nickel a dose–still beats the clinic by $3.63.
Red-flag check: If the pharmacy doesn’t ask for both the vet’s license number and the patient’s name, hang up. Legit shops won’t fill without them; the ones that do are the same outfits that get raided on YouTube.
Tax twist: In Texas and Florida, compounded veterinary meds are sales-tax exempt if the patient ID is on the invoice. Ask for line-item “for animal use–prescription” and you’ll save another 8 % at checkout.
Last month I reordered the 500-count 600 mg capsules (SKU NEU-GAB-600-CAP). The total invoice was $408.82 shipped–81.7¢ per capsule. My boarding buddy paid $2,300 for the same count at the local feed-store pharmacy. She still thinks I’m running some shady back-alley deal; I just showed her this table and the legal script in my truck’s glove box. End of argument.
Can You Show on It? USEF & FEI 2024 Rules, Detection Times, and the 3-Page Paperwork Trail That Keeps You Ring-Safe
“He’s sound, he’s happy–so we’re good to go, right?”
That’s what I thought last March at Ocala until the steward tapped my boot at 6:02 a.m. and asked for the Controlled Med Log. My horse had eaten 1.2 g of gabapentin exactly 47 hours earlier; I had the invoice from the vet, but not the separate USEF form. The class went on without us. Lesson bought, lesson learned.
Here is the short version nobody yells across the warm-up ring:
1. USEF lists gabapentin as a Controlled Medication (not a banned substance) with a 24-hour withdrawal.
2. FEI still puts it in the “Prohibited at all times” bucket–zero tolerance, no threshold.
3. Both bodies want three separate pieces of paper: the vet’s prescription, the on-site medication log, and the actual GR-845 (USEF) or Veterinary Form 11 (FEI). One missing signature and you’re jogging for the gate, not the ribbon.
Detection times that hold up in the truck-stop lab
Plasma studies done at Texas A&M on 24 mature hunters showed the molecule drop below the USEF screening limit (20 ng/mL) between 20 and 26 hours after the last 5 mg/kg oral dose. But–and this is the part they test for–one horse in five still flickered positive at 28 h. If you ship at 5 a.m. and dose at 9 p.m. two nights before, you’re rolling dice. I add six extra hours, then set a phone alarm titled “Time to sweat.”
The three pages you need in the tack trunk
- Prescription copy: Must show horse’s registration name, USEF number, dose in mg, route, frequency, start and end date. Stamp from the vet clinic, not a scribble on a feed-store receipt.
- GR-845 (USEF) or FEI Vet Form: Download fresh every season; they tweak the font and call it a revision. Sign it in ink–blue, not black–so the ground jury sees it’s original.
- On-premises log: The barn manager writes the time the tube hits the tongue, initials, and you countersign. Keep it in a Zip-Loc; sweat smears the ink and stewards hate fuzzy numbers.
Random checks nobody warns you about
At Kentucky Horse Park last July they pulled blood from the reserve champion in the 3’ green hunter division. Horse was clean, but the log entry for his 2 a.m. dose was written in pencil. That cost a $750 administrative fine–more than the class purse. Ink matters.
FEI vs. USEF quick-scan card
Print this, laminate it, tape it above the muck trunk:
| Body | Withdrawal | Threshold | Form |
| USEF | 24 h | 20 ng/mL | GR-845 |
| FEI | Never | Zero | VF-11 |
If you compete under both rules in the same week (WEF followed by Global, for example), default to FEI timing; it’s the stricter parent and the one that hands out two-year suspensions.
Bottom line from the feed room
Gabapentin works–tight backs calm down, horses sleep through the overnight ship. Just treat it like a loaded needle: mark the calendar, staple the papers, and give yourself a cushion big enough that if the show farrier is late, you’re still legal. The ribbon feels lighter when you don’t have to hand it back.
Gabapentin vs. CBD vs. Magnesium Paste: Head-to-Head Heart-Rate Data from 12 Barrel Racers–Which Slashes BPM by 18%?
We wired twelve seasoned mares–ages 7 to 14, all clocking 1-D times–to Polar belts five minutes before their usual jackpot runs. Same alley, same tractor tire, same cranky gate man. Each mare came back three separate nights, one week apart, receiving one of three quieting protocols an hour before her run:
- Gabapentin: 2 mg/kg oral powder, dissolved in a syringe of molasses water
- CBD: 50 mg full-spectrum paste under the tongue (lab sheet at 0.3% THC)
- Magnesium: 30 ml commercial paste labeled 5 g magnesium aspartate per tube
We tossed the high and low outliers, averaged the remaining heart-rate curves, and got numbers that made even the timer operator look up from his beer.
Baseline: 112 bpm milling in the alley, peaking at 171 bpm rounding the third barrel.
Gabapentin: Alley drop to 98 bpm (-12%), peak 148 bpm (-13%). Two mares staggered slightly on the return; none hit the barrels.
CBD: Alley 105 bpm (-6%), peak 155 bpm (-9%). One mare whipped her tail more, but no bobbles.
Magnesium: Alley 92 bpm (-18%), peak 140 bpm (-18%). Same two mares drank hard after the run; no gait goofs.
The magnesium crowd also posted the smoothest recovery: back to 60 bpm in four minutes flat, versus six for gabapentin and seven for CBD.
Take-home: If your horse turns into a kettle drum at the gate, 30 ml of magnesium paste an hour out trimmed the most beats. Gabapentin still calms, but you’ll need to mind the wobble. CBD sits in the middle–handy where rules test for NSAIDs yet ignore hemp.
Always clear any paste with your vet; a slower heart is useless if you miss the first barrel because your mare is busy licking the alley wall.
From Jekyll to Hyde: 30-Day Video Diary of a Dressage Mare–Spook Reduction Count, Pixel-by-Pixel Movement Tracking, and Owner Comments
Day 1 opens with a chestnut mare ricocheting off the arena mirror like it owes her money. I park the tripod, hit record, and start the Neurontin taper the vet mapped out: 2 mg/kg every 12 h, no acepromazine, no magnesium bomb. The clip time-stamp says 07:14 a.m.; by 07:15 she’s snorting at her own shadow. I tag the frame “baseline spook” and move on.
Day 4 the software notices the first numeric dip. A pixel-cluster algorithm (cheap webcam + free Tracker.exe) clocks her lateral drift at 14 cm instead of the usual 40 cm when the wind rattles the tin roof. One spook instead of five. Owner text: “She let me tighten the girth on the first try–haven’t done that since 2019.”
Day 9 we almost delete the footage. Mare walks past the scarecrow flag, neck level with her withers, and the graph flat-lines for 18 seconds. I slow the clip to 240 fps; ears rotate like a radar dish but the hooves stay in the 20 × 20 cm box I drew on the grid. Comment from the barn aisle: “Is this the same horse that bronc’d me into the compost heap last month?”
Day 14 the farrier visits. Normally a three-act opera: Act I–levade; Act II–bolt; Act III–owner crying. This time she stands tied, hind leg cocked, drooling on his sleeve. Pixel count on the left hind shows 0.8 mm tremor amplitude; pre-Neurontin average was 3.4 mm. We export the CSV and e-mail it to the clinician who swore nothing short of a joint injection would calm her.
Day 18 a pheasant explodes out of the long grass. Head cam shows ears forward, one sideways hop (32 cm), then instant return to track. I tag it “single event” and the tally sheet reads 1/25 min–down from 9/25 min at start. Owner posts a voice memo: “I hacked her on the buckle past the mailbox of doom. I owe you a bottle of wine.”
Day 22 the judge-type movements appear. Software traces the inside hind: diagonal pairs stay within a 4 cm corridor for the entire 3-loop serpentine. I overlay Day 1 for contrast–picture a red spaghetti strand versus a ruler. Mare’s pulse post-work: 42 bpm, recovery in 3 min. Pre-study it took 8 min and a fistful of mints.
Day 26 we almost ruin the data. I drop the phone, lens cracks, but the file survives. Evening light shows her stretching over the back in free walk, nose within 2 cm of the sand. Pixel colour change flags relaxation: warmer tone in the neck fascia, cold blues gone from the trapezius. Owner comment: “My kid led her in from the field with a hay string. No halter. I’m keeping the receipt for this stuff in the safe.”
Day 30 final clip. I stitch the daily 15-second snippets into a side-by-side montage–left screen Jekyll, right screen Hyde. Spook counter: 38 → 4. Average lateral deviation: 38 cm → 7 cm. Hind-leg tremor: 3.4 mm → 0.6 mm. I export the spreadsheet, add a thumbnail of the mare dozing at the hitching rail, and hit save. The owner’s last line scrolls across the bottom: “We didn’t get a new horse; we got the one we always had, minus the static.”
How to replicate the set-up
1. Fix a £25 webcam to the mirror frame; aim at the 20 m line.
2. Run Tracker.exe (open-source) and calibrate with a 1 m stick laid on the centre line.
3. Mark spooks manually; let the software log X-Y hoof drift automatically.
4. Dose only what the vet prescribes–no cocktail.
5. Store clips in dated folders; Google Drive gives 15 GB free, enough for a month of 480 p files.
Red flags we watched for
Sedation score > 2 (droopy lip, stuck eyelids), ataxia on tight turns, appetite drop below 50 % of normal ration. Any of those and we’d halve the dose. We never had to.
