What are Dortimopt Eye Drops?

Dortimopt eye drops are a prescription medication used to treat glaucoma, a condition characterised by increased pressure in the eye. This medication combines two active ingredients, Dorzolamide Hydrochloride and Timolol Maleate, to effectively reduce intraocular pressure and maintain eye health. It is a human medication that may be prescribed off-label by veterinarians for use in pets.

How does it work?

Dorzolamide reduces fluid production in the eye, while Timolol Maleate is a beta-blocker that helps lower intraocular pressure. The combination of these two ingredients aid in reducing fluid buildup (aqueous humour) and eye pressure.

Dose and Administration

Follow directions as prescribed by your veterinarian. To administer the drops, gently tilt your pet's head back and use the first finger of the same hand to hold the upper eyelid open. Care should be taken to avoid contamination of the dropper or touching it against the surface of the eye. Once you've administered the dose, keep your pet's head tilted back for a few seconds to ensure the drops are absorbed properly. Always follow up with praise to positively reinforce the experience. 

Contraindications and Precautions

Hypersensitivity to dorzolamide or any component of the formulation. Animals with a known allergy to this medication should not be given dorzolamide.

Caution is advised when using dorzolamide in animals with pre-existing kidney or liver disease, as well as those with electrolyte imbalances, due to potential exacerbation of their conditions or increased risk of side effects.

Corneal disorders: Avoid use in cases of corneal ulceration.

Pregnancy and Lactation: Avoid use in pregnant or lactating animals.

Potential Side Effects

Inform your vet if you have think your pet is experiencing side effects. Possible side effects of this medication may include a stinging sensation in the eyes after application, as well as eye inflammation, which is marked by redness, watering, and sensitivity to light. Other potential side effects may include dry eyes, a runny nose, or feelings of nausea or vomiting. More serious side effects that require immediate medical attention include cloudy or blue eyes, difficulty breathing (which may indicate an allergic reaction), fever, or a skin rash.

Storage

Keep the medication at room temperature and avoid freezing. Ensure it is kept out of reach of children and pets.
