Rashes Caused by Beta Blockers
A rash in many cases develops while taking a beta blocker, which is used in the treatment of high blood pressure and other conditions. Depending on the severity of the problem, the use of a topical cream or medical attention may be required.

What are Beta Blockers?
-
Beta blockers are drugs used to treat heart conditions, hypertension, glaucoma, migraine and psychiatric disorders, such as performance anxieties. Some commonly used beta blockers are nadolol, metoprolol and atenolol.
Purpose
-
Beta blockers affect the central nervous system, controlling mental alertness, lung function, heart rate and blood vessels. The most important function is that it slows the heart rate to a normal rate and rhythm.
-
Dosage
-
The dosage is based on the condition being treated. For example, 10 to 40 mg for performance anxiety, 20 to 60 mg for lithium-induced tremors, and 10 to 30 mg for the treatment of akathisia.
Warning
-
Individuals with blood pressure levels 90/60 mmHg and below, or a resting heartbeat of 55 per minute, should not use beta blockers, because it decreases the heart rate. Beta blockers can also cause a skin rash.
Rashes
-
A rash is rarely fatal, but medication that causes a rash should be discontinued. Individuals who are allergic to drugs containing sulfa should refrain from using of these drugs.
Treatments
-
Treatment includes discontinuing the use of the medication and consulting the prescribing physician for a replacement. A topical itch or non-itch cream can be used to remove or relieve the symptoms of a rash.
