What is homatropine ophthalmic (Isopto Homatropine)?

Homatropine ophthalmic causes the muscles in your eye to become relaxed. This widens your pupil. Your pupil will remain wide and will not respond to light.

Homatropine ophthalmic is used to dilate (widen) your pupil when you have an inflammatory condition or in diagnostic or postsurgery situations in which this effect may be helpful.

Homatropine ophthalmic may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of homatropine ophthalmic (Isopto Homatropine)?

If you experience any of the following serious side effects, stop using homatropine ophthalmic and seek emergency medical attention:

  • an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives);
  • an irregular or fast heart rate;
  • hallucinations or unusual behavior (especially in children); or
  • a swollen or distended stomach (in infants).

Other, less serious side effects may be more likely to occur. Continue to use homatropine ophthalmic and talk to your doctor if you experience

  • blurred vision,
  • sensitivity to sunlight,
  • stinging and burning, or
  • swelling of the eyelids.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.

What is the most important information I should know about homatropine ophthalmic (Isopto Homatropine)?

Do not touch the dropper to any surface, including your eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in your eye.

Apply light pressure to the inside corner of your eye (near your nose) for 1 to 3 minutes after each drop to prevent the medicine from draining down your tear duct.

Use caution when driving, operating machinery, or performing other hazardous activities. Homatropine ophthalmic may cause blurred vision. If you experience blurred vision, avoid these activities. The effects of even one drop of this medication can last for up to 3 days. Be sure that your vision is clear before attempting any activity that could be dangerous.

Homatropine ophthalmic may make your eyes more sensitive to light. Protect your eyes when you are going to be in bright light.
