What is the most important information I should know about homatropine ophthalmic?

You should not use this medicine if you have glaucoma.

What is homatropine ophthalmic?

Homatropine relaxes muscles in the iris (the colored part) of your eye. Relaxing these muscles helps to dilate or widen your pupil.

Homatropine ophthalmic (for the eyes) is used to treat an eye condition called uveitis. This medicine is also used to dilate your pupil before an eye exam, or to lower pressure inside the eye after eye surgery.

Homatropine ophthalmic may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before using homatropine ophthalmic?

You should not use this medicine if you are allergic to homatropine, or if you have:

  • glaucoma, or
  • if your eye doctor has found changes in your eyes that could be signs of glaucoma.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.

It is not known whether homatropine ophthalmic passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How should I use homatropine ophthalmic?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not use this medicine while wearing contact lenses. Homatropine ophthalmic may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.

To treat uveitis, you may need to use homatropine ophthalmic every 3 to 4 hours.

Wash your hands before using the eye drops.

To apply the eye drops:

  • Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
  • Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
  • Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
  • Wait at least 10 minutes before using any other eye drops your doctor has prescribed.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.

Store at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Apply the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.

What should I avoid while using homatropine ophthalmic?

This medicine may cause blurred vision and may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.

Homatropine ophthalmic can make your eyes more sensitive to light. Protect your eyes when you are outdoors in sunlight.

What are the possible side effects of homatropine ophthalmic?
