labetalol side effects
The most common side effects of labetalol are fatigue, dizziness, headache, diarrhea, edema (fluid accumulation), dry eyes, and tingling of the scalp and skin. Postural hypotension (a rapid decrease in blood pressure when going from the lying or seated position to the standing position that may cause light-headedness or fainting) occurs rarely. Patients should be observed for these possible labetolol side effects within two to four hours of the first labetalol dose and after any changes in dose. Sexual dysfunction, abnormal heart rhythm and difficulty breathing also may occur.
Sometimes a medicine causes unwanted effects. These are called side effects. Not all of the side effects for beta-blockers or labetalol side effects are listed here. If you feel these or any other effects, you should check with your doctor. Side effects may be less if labetalol is given in three daily doses rather than two. Stopping or changing the dose of the drug should be directed by a physician because serious side effects may occur.
