Alphagan
Alphagan reduces elevated pressure in the eyes of patients who have open angle glaucoma or high blood pressure of the eye. Follow your pharmacist's instructions on how to properly administer eyedrops.
Alphagan Overview
Alphagan is a prescription medication used to reduce pressure in patients with open-angle glaucoma or ocular hypertension (higher than normal blood pressure inside the eye).
Alphagan belongs to a group of drugs called alpha adrenergic agonists. These work by decreasing the amount of fluid produced in the eyes, which reduces overall pressure within the eye.
This medication comes in eyedrop form and is typically taken three times daily, with administrations approximately 8 hours apart.
Common side effects of Alphagan include irritation of the eye such as redness, burning, and stinging.
Alphagan can cause blurred vision. Do not drive or operate heavy machinery until you know how Alphagan affects you.

Alphagan and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Alphagan falls into category B. There are no well-done studies that have been done in humans with Alphagan. In animal studies, pregnant animals were given this medication, and the babies did not show any medical issues related to this medication. Alphagan should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.
Alphagan and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if Alphagan crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Alphagan.
