What should I know about Istalol (timolol ophthalmic) before taking it?

You should not wear soft contact lenses while you take Istalol (timolol ophthalmic), a prescription eyedrop that treats open-angle glaucoma.

You can insert your contacts 15 minutes after using the drops. Do not touch the tip of the dropper with your eyes, hands, or anything else, as it could transmit germs to your eye, which could lead to a potentially blinding infection. Do not take Istalol if you have asthma, specific heart problems (including AV block or congestive heart failure that is uncontrolled or severe), or chronic obstructive pulmonary disease that is severe.

Avoid taking Istalol if you have a timolol allergy. This medication can make you sleepy and it can blur your vision, so use caution when driving or doing any other dangerous tasks. Istalol can also make you dizzy, so avoid getting up too quickly from a lying or sitting position. You may need to wear sunglasses to shield your eyes from bright light.
