As the weather warms up, many of us are spending more time outdoors—but did you know that sunlight can interact with certain medications in ways that may be harmful?

Some medications can make your skin more sensitive to sunlight, a reaction known as photosensitivity. This happens when certain drugs react to ultraviolet (UV) rays from the sun, making your skin more vulnerable to damage.

​There are two main types of reactions:

• ​Phototoxic reactions - the most common; these can feel like an intense sunburn and may happen within minutes or hours of sun exposure
• ​Photoallergic reactions - less common; these involve the immune system and may appear as a rash a day or two after exposure

​For seniors, especially those taking multiple medications, this risk can be higher and sometimes more severe.

Here are several types of medications that may cause increased sensitivity to sunlight:

• ​Antibiotics like Doxycycline and certain fluoroquinolones
• ​Diuretics (water pills) such as Hydrochlorothiazide, often used for blood pressure
• ​NSAIDs (pain relievers) like Ibuprofen and naproxen
• ​Heart medications such as Amiodarone
• ​Retinoids used to treat acne or other skin conditions
• ​Antihistamines and certain allergy medications
• ​Diabetes medications (in some cases)
• ​Antidepressants and anti-anxiety medications

​Even over-the-counter medications and topical creams can increase your sensitivity so it's

A few simple precautions can make a big difference in protecting your skin:

• ​Use a broad-spectrum sunscreen (SPF 30 or higher) and reapply every 2 hours, or more often if swimming or sweating
• ​Choose sunscreen with zinc oxide or titanium dioxide for added protection
• ​Wear long sleeves, wide-brimmed hats, and UV-blocking sunglasses
• ​Try to avoid peak sun hours (10 AM-4PM) when UV rays are strongest
• ​Seek shade whenever possible
• ​Stay well-hydrated, especially on hot days
• ​Be extra cautious near water, sand, or concrete, which can reflect sunlight and increase exposure

Watch for these symptoms after spending time in the sun:

• ​Redness or sunburn that develops quickly
• ​Skin that feels hot, painful, or tender
• ​Blistering or peeling
• ​Itchy rash or hives
• ​Darkening or discoloration of the skin

​If you notice any of these, limit further sun exposure and contact your doctor or pharmacist.

Before heading into the sun this season, take a moment to:

• ​Ask if any of your medications increase sun sensitivity
• ​Discuss possible alternatives if you've had reactions before

​A quick conversation can help you avoid uncomfortable or even dangerous side effects.
