Side Effects Of Calcium Channel Blockers

Rash or Flushing

Taking calcium channel blockers could sometimes result in a rash or flushing, although this is fairly rare. Among patients taking a type of calcium channel blocker known as amlodipine, rashes or flushing occurred in only one to two percent of cases. Generally, the rash associated with a calcium channel blocker will be a maculopapular rash with both flat and raised areas and skin discoloration. Flushing is often mild, but it might appear like a sunburn in some individuals. Patients may want to take a photo of any rash or flushing to show to their doctor, and it can be helpful to photograph any changes. Most skin rashes related to calcium channel blockers will resolve on their own within a few days. However, some patients using this medication could develop a potentially serious skin condition known as erythema multiforme. This condition is considered an allergic reaction, and it involves raised, red lesions, painful blisters, and itchy nodules. This type of skin issue could progress to a skin infection and the potential death of skin tissue. To reduce the risk of these complications, patients who notice any changes to their skin while on this medicine should have a prompt examination.
