High Blood Pressure Medications May Cause Photosensitivity

 

Like all others, medicines for high blood pressure also have side effects. One of their side effects is photosensitivity or in layman’s term, sensitivity to sunlight. What happens when you take these medicines is that the UV wavelengths of light that are present in sunlight, break down larger molecules found in the drugs, consequently forming new molecules and liberating free radicals. These free radicals are small molecules that bond to other molecules and may form a hapten, which is a small molecule that triggers an allergic reaction from the immune system in the form of a skin rash or irritation.

High Blood Pressure Medications May Cause Photosensitivity?

Two drugs that have been known to cause photosensitivity are Amiodarone (Cordarone) and Quinidine (Quinidex). Both these drugs are prescribed for the heart condition called arrhythmias in which the heart has an improper rhythm. Irregular or skipped heartbeats, palpitations, shortness of breath, light-headedness, fainting or pains in the chest are some of the symptoms of arrhythmias.

People with high blood pressure are also prescribed diuretics that work by preventing salt from being reabsorbed by the distal tubules, reducing the salt concentration and water presence in the body through excretion. Reduced fluid levels lead to a lower blood pressure. Certain diuretics like Thiazides and sulfonamides have also been linked to photosensitivity.

Usually photosensitivity is a temporary reaction to medicines and goes away when the drug treatment is halted. In some cases, it has been reported to persist even after stopping the medicines. The irritation is treated topically as any other skin irritation or rash.
