This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.

Precautions
If eye pain or change in vision occurs or if redness or irritation of the eye continues, gets worse, or lasts for more than 72 hours, stop using the medicine and check with your doctor.
For patients using the 2.5 or 10% eye drops:
- After you apply this medicine to your eyes, your pupils will become unusually large. This will cause your eyes to become more sensitive to light than they are normally. When you go out during the daylight hours, even on cloudy days, wear sunglasses that block ultraviolet (UV) light to protect your eyes from sunlight and other bright lights. Ordinary sunglasses may not protect your eyes. If you have any questions about the kind of sunglasses to wear, check with your doctor. Also, if this effect continues for longer than 12 hours after you have stopped using this medicine, check with your doctor.
