Can blood pressure medication cause itchy skin?

Blood pressure medication comes with potential side effects, such as itchy skin (pruritus). Itching is a common problem with many possible causes, so rule out any other culprit before assuming it’s your medication.

Dust and pet hair can irritate the skin, as can perfumes, lotions and laundry detergents that contain fragrance. Check your home for anything that may trigger itching and remove it, if possible. If you find a product that’s making you itch, switch it for a fragrance-free or non-bio alternative to see if it makes a difference.

Other things you can do at home to help soothe your skin include wearing breathable materials like cotton, especially at night, or swapping your duvet for a sheet when it’s warm. Applying fragrance-free creams to the itchy skin can also help bring relief.

When taking a bath, keep the water cool. You could also place some oatmeal in a sock and let it soak in your bath water. If the itching persists, an allergy medication (antihistamine) may help. Ask your pharmacist if it’s safe to take it with your other medication. You could also ask your pharmacist if any of your prescriptions, or their combination, could be causing the problem.

If none of these remedies help, and you suspect your medication may be causing the itching, speak to your GP. Your GP may suggest a trial period without the medication, reduce the dose you’re on, or change your medication altogether. They may also refer you to a dermatologist or another specialist who may order some tests to find out what’s causing the itching and how to relieve it.
