A veterinary prescription indicates Methimazole 5 mg per 0.1 mL; apply 2.5 mg once daily. How many mL per dose?

Calculating the volume to administer uses Volume = Dose ÷ (Concentration). The solution has 5 mg in 0.1 mL, which is 50 mg per 1 mL. To give 2.5 mg, the needed volume is 2.5 mg ÷ 50 mg/mL = 0.05 mL. So each dose should be 0.05 mL (which is 1/20 of a milliliter). The small volume comes from the high concentration: 50 mg per milliliter, so a 2.5 mg dose is a tiny fraction of a milliliter.
