Quick Answer

Goat medications are dosed by body weight, and nearly all of them are used extra-label (off-label), which legally requires your veterinarian to set the exact dose and withdrawal time. Always weigh your goat, draw up the dose for that weight, and confirm meat and milk withdrawal before treating. Use the charts below as a reference, not a prescription.

A goat that is sick, injured, or wormy almost always needs the right medicine at the right dose, fast, and the single most common mistake new owners make is guessing. After years of scribbling doses on barn whiteboards and the backs of feed sacks during 2 a.m. emergencies, I built the weight-based reference I wish I’d had on day one. Goats are not small cattle: they clear many drugs from their system quicker, so the doses and withdrawal times are different, and almost every medication on this page is used extra-label (not officially approved for goats).

This chart pulls together the doses most commonly cited by veterinary and breeder sources, with the meat and milk withdrawal times that most quick-reference charts leave out. Read the safety section first, weigh your goat, and confirm anything you are unsure about with your vet before you draw up a syringe.

Important: This article is an educational reference, not veterinary advice or a prescription. Because these drugs are extra-label in goats, U.S. law requires a valid veterinarian-client-patient relationship (VCPR) for your vet to set the legal dose and withdrawal time. Doses below are commonly published figures and can vary by product strength, illness severity, and individual goat.

How to Use This Dosage Chart

Every dose on this page depends on three numbers you must confirm yourself:

  1. Your goat’s weight, every dose is per pound or per kilogram. A guess of “about average” can mean a 40% error. See how to find your goat’s weight below.
  2. The product’s concentration, the same drug comes in different strengths. “Oxytetracycline 200” means 200 mg/mL; a 100 mg/mL bottle needs double the volume for the same dose. Always read the label.
  3. The withdrawal time, how long after the last dose before the milk or meat is safe for people. Extra-label use almost always extends the label withdrawal, so your vet must set it.

To convert weight: 1 kg = 2.2 lb. So a 10 mg/kg dose for a 110 lb (50 kg) goat is 500 mg of active drug.

How Goat Medication Dosing Works

Extra-label is the rule, not the exception. Only a handful of products are FDA-approved for goats. Everything else, most antibiotics, dewormers, and pain relievers, is borrowed from cattle, sheep, or even human medicine and used off-label. That is legal only through your veterinarian, who is also the only person who can legally tell you the correct withdrawal time for an extra-label drug.

Goats burn through drugs fast. Their rumen and liver metabolize many compounds more quickly than cattle do. That is why several goat dewormers are dosed at roughly double the cattle label, and why short-acting drugs may need more frequent dosing. Never assume the cattle label is correct for a goat.

Drawing up a weight-based dose of goat medication into a luer-lock syringe

Route matters. Most goat injections are given SQ (subcutaneous, under the skin) rather than IM (into the muscle), because IM injections can cause muscle damage and abscesses and ruin meat. A few drugs are still given IM or IV, the charts note which.

How to Find Your Goat’s Weight

You cannot dose safely without a weight. Three reliable options, best first:

  • Digital livestock scale, most accurate. A platform scale or a hanging scale with a sling for kids.
  • Weigh tape (goat-specific), a cloth tape you wrap around the heart girth (just behind the front legs). Quick and cheap; accurate to within about 5 to 10%.
  • Heart-girth formula, measure the heart girth in inches, square it, multiply by the body length (point of shoulder to pin bone), and divide by 300. It is rough but better than guessing.

For kids and bottle babies, a kitchen or luggage scale works in a pinch. Re-check weight before every treatment course, a wormy or scouring goat can lose weight fast.

Goat Dewormer Dosage Chart

Goat dewormers are dosed orally and almost always above the cattle/sheep label. Resistance is widespread, so deworm based on a fecal egg count and FAMACHA score rather than on a calendar, and rotate classes only on your vet’s advice. Doses below follow Cornell University’s dewormer chart for goats.

Dewormer (brand)ClassOral doseMeat withdrawalMilk withdrawalNotes
Fenbendazole (Safe-Guard, Panacur)Benzimidazole10 mg/kg16 days4 daysOften resistant; add 1 withdrawal day per extra treatment day
Albendazole (Valbazen)Benzimidazole20 mg/kg9 days7 daysDo not use in the first trimester of pregnancy
Ivermectin (Ivomec sheep drench)Macrocyclic lactone0.4 mg/kg14 days9 daysUse the oral drench, not the pour-on
Moxidectin (Cydectin sheep drench)Macrocyclic lactone0.4 mg/kg17 days8 daysUse the sheep oral drench, not cattle
Levamisole (Prohibit, LevaMed)Imidazothiazole12 mg/kg4 days3 daysNarrow safety margin, weigh accurately
Morantel (Rumatel)Tetrahydropyrimidine10 mg/kg (in feed)30 days0 daysFeed pre-mix

If you are using a pour-on or a cattle dewormer block, stop and confirm the goat dose first, those are common sources of under-dosing and resistance.

Goat Antibiotic Dosage Chart

All goat antibiotics are extra-label and must be prescribed. Doses vary by source and by infection, and milk withdrawals are long. The figures below are commonly cited references, your vet sets the legal dose and withdrawal.

Antibiotic (brand)Used forCommonly cited doseRouteMilk withdrawal*
Procaine penicillin G (300k IU/mL)Strep, listeriosis, wounds, tetanus support~1 mL per 15-20 lb, 1-2× dailySQ14-20 days

*Withdrawal times for extra-label use are estimates only; your veterinarian must set the legal withdrawal. For pregnant does and young kids, see our notes on penicillin in pregnant goats and penicillin overdose in kids.

Pain and Anti-Inflammatory Medications

DrugUseCommonly cited doseRouteNotes
Flunixin meglumine (Banamine, 50 mg/mL)Pain, fever, inflammation~1 mL per 100 lb, once daily, ≤3 daysSQ (IV by vet)NSAID; ulcer and kidney risk; milk withdrawal ~3-4 days
MeloxicamLonger-acting pain control~0.5 mg/kg orally, per vetOralVet-preferred modern NSAID

See our full guide to Banamine for goats for the complete dosage chart by weight and safety rules. Never stack two NSAIDs, and never use Banamine IM (it causes severe tissue damage). For digestive upset, see Pepto-Bismol for goats and avoid human painkillers unless your vet directs.

Coccidiosis Treatment

Coccidiosis is a leading killer of kids 3 weeks to 5 months old. Treat at the first sign of scours and dehydration. For the full amprolium protocol, dosage by weight, the thiamine/polio warning, and prevention, see our guide to Corid for goats.

Emergency Medications to Stock

Some problems move too fast to wait for a vet visit. Keep these on hand and know the dose before you need it:

  • Epinephrine (1 mL per 100 lb, IM), for anaphylactic shock. Keep it within reach every time you give an injection, especially CD&T or penicillin, which can trigger a fatal reaction within minutes.
  • CD antitoxin, for suspected enterotoxemia (overeating disease).
  • Propylene glycol, for pregnancy toxemia and ketosis.
  • CMPK / calcium drench, for milk fever (hypocalcemia) in late-pregnant or fresh does.
  • Activated charcoal, for many plant and chemical poisonings.
  • Baking soda (free choice or drenched), for early frothy bloat; know when bloat needs a vet, not baking soda.
  • Electrolytes + probiotics, for any scouring or off-feed goat.

How to Give a Goat an Injection

Most goat injections are SQ (under the skin):

  1. Draw up the correct dose for your goat’s weight using a luer-lock syringe and an 18 to 20 gauge, 3/4 to 1 inch needle.
  2. “Tent” a fold of loose skin over the ribs or behind the front leg.
  3. Insert the needle into the tent (parallel to the body, not into muscle), pull back slightly to check you are not in a blood vessel, and inject.
  4. Rub the site. Use a fresh needle per goat to avoid spreading infection.

For IM injections (only when a drug requires it), use the muscle of the neck or hindquarters and never exceed about 5 mL per site. When in doubt, default to SQ unless the label or your vet says otherwise.

Meat and Milk Withdrawal Times

Withdrawal time is how long after the last dose you must wait before milk or meat is safe for people. It exists to keep drug residues out of the food supply, and ignoring it is both unsafe and illegal for animals entering the food chain.

Two rules to live by:

  • Extra-label use extends withdrawal. The label time on a cattle or sheep product is not valid when the drug is used off-label in a goat. Your vet must assign the goat withdrawal.
  • When in doubt, dump and wait longer. If you cannot confirm a withdrawal time, discard the milk and do not slaughter until your vet clears it.

Goat Medicine Cabinet Essentials

If you keep goats, stock these before an emergency forces a 2 a.m. supply run:

  • Digital thermometer (normal goat temp is about 101.5-103.5°F)
  • Goat-specific weigh tape or a livestock scale
  • Luer-lock syringes (3, 6, and 12 mL) and 18-20 gauge needles
  • A drench syringe for oral meds and electrolytes
  • A current dewormer matched to your fecal results
  • CD antitoxin and epinephrine (vaccine-reaction rescue)
  • Electrolytes, probiotic paste, and baking soda
  • Vet wrap, iodine, and a sharps container

A small, well-labeled kit with a printed copy of this chart taped inside the lid will save you in the moments that matter.

Frequently Asked Questions

Weigh the goat (or estimate with a weigh tape), find the medication's per-pound or per-kilogram dose, and multiply. For example, a drug labeled 1 mL per 50 lb given to a 100 lb goat is a 2 mL dose. Always round to your goat's actual weight and double-check the concentration printed on the bottle, since the same drug name can come in different strengths.

Procaine penicillin G (300,000 IU/mL) is most commonly cited at roughly 1 mL per 15 to 20 lb of body weight, given under the skin once or twice daily for at least 5 days. Penicillin is extra-label in goats, doses used in practice are often higher than the label, and milk withdrawal is long (about 14 to 20 days), so confirm the exact dose and withdrawal with your vet.

Flunixin meglumine (Banamine, 50 mg/mL) is commonly given at about 1 mL per 100 lb of body weight, once daily, for no more than 3 days. It is an NSAID that can cause stomach ulcers and kidney damage if overused, so it should not be given long-term without veterinary guidance.

Often yes, but goats metabolize many drugs faster than cattle, so cattle doses are frequently too low and the route can differ. Several goat dewormers are dosed at roughly double the cattle or sheep label. Because this is extra-label use, your vet must set the correct dose and withdrawal time for each product.

Yes. This page is built to print cleanly to PDF directly from your browser (File then Print then Save as PDF), so you can keep a copy in your medicine kit. Re-download it periodically, since recommended doses and withdrawal times are updated over time.

A basic goat medicine cabinet includes a digital thermometer, a dewormer, CD antitoxin, electrolytes, probiotics, Banamine or another vet-prescribed anti-inflammatory, injectable epinephrine for vaccine reactions, baking soda for early bloat, and luer-lock syringes with 18 to 20 gauge needles. See the medicine cabinet section below for the full list.
