Administering medication to a guinea pig can be difficult. Guinea pigs usually don't enjoy being restrained and don't take medication willingly. Below are techniques for giving liquid and tablet medication.
Liquid Medication
Draw up the prescribed amount of medication in a syringe or eyedropper.
Hold the head and neck of the guinea pig with one hand.
Use the other hand to place the tip of the syringe or eyedropper just behind the front teeth.
The guinea pig will usually open his/her mouth trying to remove the syringe.
While the guinea pig is chewing at the syringe or eyedropper, slowly administer the medication.
Tablet Medication
Tablets are very difficult to give to guinea pigs. Consider obtaining a pill crusher at a local pharmacy.
Crush the medication using a pill crusher or other method.
Once the medication is in powder form, mix the medicine with a small amount of flavored Sustacal or Ensure.
About 1/4 teaspoon (1 ml) of flavored diet supplement should be enough.
After mixing the powdered medication with the supplement, follow the instructions for administering liquid form medication.
