Drug Dosage Calculator for Rabbits
Note: an accurate weight is essential for calculating doses. This calculator provides a mean dosage. You should not blindly accept the dosage provided by the calculator since there is a range of valid doses for any given drug. Your vet may decide to prescribe a much higher or lower dose depending on other drugs being taken by the rabbit, the type of illness, infection, the effect desired, etc. |
If your veterinarian provides you with the concentration of a drug, to calculate the amount of medicine to administer to your bunny, divide the dose obtained from the drug dose calculator by the concentration of medicine, usually written on the bottle. Make sure that the units from the bottle are the same as those computed by the drug dose calculator.
For example:
The Drug Calculator computes 17 mg of ibuprofen for a 5-pound bunny. If the children's Ibuprofen concentration is listed as 100 mg per tsp on the label, then to obtain the amount in cc (ml), divide the dose by the concentration and perform units conversion (1 tsp = 5 cc, according to the Measures and Conversions table below):
Amount of liquid = dose / concentration
Amount of liquid = 17 mg / [ (100 mg/tsp) * (1 tsp/5 cc) ]
Amount of liquid = 17 mg / (20 mg/cc)
Amount of liquid = 0.85 cc
Make sure you confirm the dose with your vet before administering the medicine.
If you administer the wrong dose to your bunny, it could be fatal!

| Measures and Conversions | Liquid Measure:
- 1 milliliter (ml) = 1 cubic centimeter (cc)
- 1 teaspoon (tsp) = 5 ml (cc)
- 1 Tablespoon (Tbsp) = 14.79 ml = 3 tsp = 1/2 oz
- 1 fluid ounce (fl oz) = 29.57 ml = 2 tablespoons
- 1 cup (cp) = 16 tablespoons = 236.6 ml
- 1 liter (l) = 1,000 ml (cc) = 1.0567 quarts
Weights:
- 1 microgram (ug or mcg) = 1,000 nanograms (ng)
- 1 milligram (mg) = 1,000 micrograms (ug or mcg)
- 1,000 mg = 1 gram (g) = 15.43 grains
- 1 grain (gr) = 64.8 mg
- 1,000 g = 1 kilogram
- 1 kilogram (kg) = 2.2046 pounds = 1,000 grams
- 1 pound (lb) = 0.4536 kg, or 453.6 grams
- 1 ounce (oz) = 28.35 g
