Herp owners are strongly encouraged to not self-treat their reptiles and amphibians without the guidance of a reptile vet. The increasing availability of over-the-counter products and some legend drugs does not mean that treating animals, including reptiles, is a straight-foward matter. There are many factors herp vets must take into consideration when deciding upon the course of treatment, drug to use, and dosage to give, factors the following document does not address. Failure to take those factors into consideration may lead to the death or permanent injury of the reptile.
The dose is the amount of drug taken at any one time. This can be expressed as the weight of drug (e.g. 250 mg), volume of drug solution (e.g. 10 mL, 2 drops), the number of dosage forms (e.g. 1 capsule, 1 suppository) or some other quantity (e.g. 2 puffs).The optimal dosage is the dosage that gives the desired effect with minimum side effects.
There are many factors taken into consideration when deciding a dose of drug including age of the patient, weight, sex, ethnicity, liver and kidney function and whether the patient smokes. Other medicines may also affect the drug dose. Dosage instructions are written on the doctor's prescription or hospital chart, and on the pharmacy label of a prescribed medicine. Dosage instructions are also found on the packaging and inserts of over-the-counter medicines.
