Liquid medications are measured in milliliters (ml) or cubic centiliters (cc), with syringes marked accordingly; while measured differently, they equal the same amount of fluid. Markings on sy ringes will vary depending on the total volume of the syringe. Syringes typically used in small animal and reptile care are 1cc, 3cc, 6cc, 12cc, 35cc, and 60cc.

Injectible medications should not be given by mouth unless specifically directed to by the veterinarian.

Keep a record of the medications your vet uses to treat your herps, whether administered in the vets office or given to you to administer at home. If you can't read the vet's writing, ask for clarification. Keep track of the drug name, strength, and dose (amount administered each time and how often it is to be administered).
