Brimonidine Side Effects
Blurred vision, headaches, and drowsiness are among the most common side effects of brimonidine eye drops. In most cases, side effects are mild and easily treated. However, there are some potentially serious reactions that require medical attention. Notify your healthcare provider right away if you develop problems such as difficulty breathing, an unexplained rash, or low blood pressure.
As with any medicine, brimonidine tartrate (Alphagan®) can cause side effects. However, not everyone who uses the medication will have problems. Most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with brimonidine. Your healthcare provider can discuss a more complete list with you.)
Some side effects with brimonidine, while occurring infrequently, are potentially serious and should be reported immediately to your healthcare provider. Such side effects include but are not limited to:
- Low blood pressure (hypotension)
- Worsening of depression
- Worsening of Raynaud's disease
- Signs or symptoms of a serious allergic reaction, such as:
- Widespread itching or hives
- An unexplained rash
- Wheezing or other difficulty breathing
- Swelling of the mouth, lips, tongue, or throat.
Of course, any eye drop can cause problems (such as an eye infection) if it is contaminated, so make sure to avoid touching the tip of the dropper to any surface, including the surface of the eye. Report any signs of an eye infection (such as severe pain, swelling, or redness) to your healthcare provider right away.
