Discontinued: "The UK Veterinary Medicines Directorate tightened enforcement through the 2024 regulations, introducing mandatory website registrations, comprehensive facility audits, and rigid annual compliance reporting deadlines. This multi-stage enforcement framework replaced low-overhead exemption benefits with substantial regulatory fees, stringent pharmacovigilance tracking, and batch-testing requirements that ultimately rendered niche house brands financially unviable." In March 2026 Molecule Group (was Vulcan Two Group plc) bought CloudRx, Webmed, and Hyperdrug and discontinued Hyperdrug's house brands.

If you have any questions on the correct dosage for your rabbit talk to your rabbit savvy vet. The information below is for reference only! The calculator will only show the dosing based on the data inputted & Hyperdrug's dosing recommendations. Talk to a rabbit savvy vet.

Each bottle contains 10 mL of ivermectin. Hyperdrug recommends 2 to 3 drops per each kilogram (kg) of body weigh. Rabbits weighing less than 0.3 kg (300 grams, 0.661 lbs) should see a rabbit-savvy vet. Using ivermectin should be dosed correctly and very accurately when using on a kit or tiny rabbit! NOTE: gtts = drops. Math is calculated based on a metric drop.

Nº of Drops to Use:
2 to 3
2 drops = 2.00 [0.100 mL]
3 drops = 3.00 [0.150 mL]
2 drops = 0.050 mg/kg
3 drops = 0.075 mg/kg

Based on the numbers entered, your rabbit of 1 kg (2.2 lbs) is using a total of 0.5 mL (1 pipettes) of Easimec. The concentration is 0.3 mg/mL, therefore your rabbit is getting a dosage of 0.15 mg/kg.

Math for a 1 kg or 2.2 lb rabbit:

2 drops = 0.1 mL x 0.5 mg/mL = 0.05 --> 0.05 / 1 = 0.0500 mg/kg
1 kg × 1000 = 1000 g ÷ 750 g = 1.33 pipettes
(1 kg × 1000 = 1000 g ÷ 750 g = 1.3333333333333 pipettes)

0.5 mL × 0.3 mg/mL ÷ 1 kg ≈ 0.15 mg/kg

0.5 mL ≈ 10 gtts (metric drops)
