Some medicines make your skin far more sensitive to sunlight, so you can burn faster or develop a rash after only a little sun. This effect—called photosensitivity—catches many people off guard because the medicine that causes it may have nothing to do with the skin. Knowing which medications can cause sun sensitivity helps you protect yourself, especially in summer or on holiday.
Key takeaways about medication photosensitivity
- Some medicines make skin burn faster or react with a rash in sunlight.
- It can happen with drugs that have nothing to do with the skin.
- Not everyone reacts, and risk can depend on the drug and dose.
- Sun protection—shade, clothing, and sunscreen—is the main defense.
- Report a suspected reaction rather than stopping a prescribed medicine on your own.
Drug types the FDA links to sun sensitivity
- Certain antibiotics, including some tetracyclines and fluoroquinolones.
- Some diuretics used for blood pressure or fluid.
- Certain NSAIDs and other pain relievers.
- Retinoids and some acne treatments.
- Some antifungals, antihistamines, and other medicines listed by the FDA.
This is not a complete list, and being on one of these medicines does not mean you will react. Check the label for a photosensitivity warning and ask a pharmacist about your specific products.
How to protect your skin
- Use broad-spectrum sunscreen and reapply as directed.
- Wear a hat, sunglasses, and clothing that covers exposed skin.
- Seek shade during peak midday sun.
- Be extra careful near water, sand, and snow, which reflect light.

Quick answers
What does drug-induced sun sensitivity feel like?
The FDA describes reactions that can look like an exaggerated sunburn—redness, stinging, or blistering—sometimes after less sun than usual. Other reactions look more like a rash or hives on sun-exposed skin. If you notice this after starting a new medicine, tell your pharmacist or prescriber.
Which medicines most often cause photosensitivity?
The FDA lists several categories, including some antibiotics, certain diuretics, some NSAIDs, retinoids, and others. Not everyone reacts, and it can depend on the specific drug and dose, so check your product's label and ask a pharmacist if you are unsure.
Should I stop my medicine if my skin reacts to the sun?
Do not stop a prescribed medicine on your own. Protect your skin from the sun and contact your pharmacist or prescriber, who can confirm whether the medicine is the cause and advise on the safest next step.
