Azopt comes as a liquid suspension that you use as an eye drop. Your doctor or pharmacist can show you how to correctly use Azopt eye drops.

Shake the bottle of Azopt well before using. You’ll place one drop in the affected eye (or eyes) three times per day. If you’re using Azopt at the same time as other eye drops, the doses should be separated by at least 10 minutes. This allows your eye to better absorb each medication.

It’s important to wash your hands before using Azopt. And when you place a drop in your eye, be sure to avoid touching the tip of the bottle to your eye. This prevents injury to your eye. It also prevents bacteria on the tip of the bottle from getting into your eye, which can lead to eye infections. Make sure to put the bottle’s cap back on right after you use Azopt.

If you wear contact lenses, you should take them out before using Azopt. Wait 15 minutes before putting your contacts back into your eyes.

If you have questions about how to use Azopt, talk with your doctor or pharmacist.


Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you’re having trouble opening medication bottles, ask your pharmacist about putting Azopt in an easy-open container. They also may recommend tools that can make it easier to open bottles.

If you miss a dose of Azopt, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and take your next scheduled dose. Do not take two doses to make up for the missed one. If you’re not sure whether you should take a missed dose or skip it, talk with your doctor or pharmacist.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.

It’s important that you don’t use more Azopt than your doctor prescribes. For some medications, using more than the recommended amount may lead to harmful effects or overdose.

If you use more than the recommended amount of Azopt
