Related Information
Tropicamide is a cycloplegic mydriatic that is primarily used to dilate the pupils in order to help in the examination of the lens and retina. It is useful in reducing pain after cataract surgery or eye injury. It may also be useful for treating glaucoma.
Tropicamide should be used cautiously in dogs with primary glaucoma, as the condition may worsen. Should tropicamide toxicity occur in a patient, changes in heart rate and rhythm may occur, which can lead to the patient being unable to urinate.
Some negative effects associated with tropicamide include sensitivity to sunlight, dry mouth, vomiting, and constipation. Should the drug get into the patient's mouth, it may cause salivation.
Tropicamide should not be used in animals with a known allergy or hypersensitivity to the drug. A veterinarian should be contacted immediately if an overdose is suspected, the symptoms of which can be colic or a dangerous increase in body temperature.
Tropicamide should be kept in a childproof container that is resistant to light. The drug should be stored at room temperature and out of reach from pets and children.
When being used to dilate the pupils, 1 drop of tropicamide is enough to induce mydriasis within 30 minutes. If it is being used to treat an eye condition, it should be administered 1-4 times a day depending on the requirements of the condition and how well the patient responds to the drug. Hands should be washed after administration in order to prevent the drug from getting into the eyes. Should a dose be forgotten, it should be administered as soon as possible. The missed dose should be skipped if it is almost time for the next scheduled dose. Two doses should not be administered at the same time.
Doses may vary in different species, when the drug is given by a different route or concurrently with other medications, and with regards to a patient's age, breed, and health status. A veterinarian's dosing instructions and/or those printed on the medication label should be followed closely.
