Some blood pressure medications can increase your skin’s sensitivity to sunlight, a phenomenon known as photosensitivity. This means your skin might react more strongly to the sun’s UV rays, potentially leading to sunburn or other skin damage.

Which Medications Are Involved?
Certain classes of antihypertensive drugs have been linked to photosensitivity. These include:
- Diuretics
- Beta-blockers
- Calcium channel blockers
- Drugs affecting the renin-angiotensin system (RAS)
Why Does This Happen?
The photosensitizing properties of these medications are related to their chemical structures, which allow them to absorb ultraviolet light. This heightened reactivity to sunlight can increase the risk of skin damage.
Increased Risk of Skin Cancer?
Studies suggest a possible link between long-term use of photosensitizing blood pressure medications and an increased risk of certain types of skin cancer, particularly lip cancer in specific populations.
Protecting Yourself
If you take blood pressure medication, it’s crucial to protect yourself from the sun:
- Wear sunscreen with a high SPF.
- Wear protective clothing.
- Seek shade during peak sun hours.
