Summer is in full swing here in Michigan and while we all enjoy the warm weather, it’s crucial to be aware of how certain medications can affect your sensitivity to the sun. I want to help you stay safe and informed about the potential risks that can come when you take certain medications and get sun exposure, which is also known as a photosensitive reaction.

It's important to be aware if medications you are taking cause photosensitivity and the potential risks that come with sun exposure. Nothing ruins a great vacation than a case of sunburn which causes you to stay indoors or visit urgent care.

MSU Health Care pharmacists are knowledgeable about medications and potential side effects. Pharmacists are available for counseling if you have any concerns or questions regarding your medications and sun sensitivity. We aim to collaborate with you and prioritize your health and well-being. Let's enjoy a healthy summer together while also being mindful of our skin and sun exposure.

What is a photosensitive reaction?

Photosensitive reactions occur when your skin becomes more sensitive to sunlight due to certain medications. This sensitivity can cause skin pain, burning, swelling, peeling or other changes that resemble a sunburn. These reactions can be uncomfortable and potentially harmful, so it’s important to take precautions.

How to protect yourself:

1. Get informed: Ask your pharmacist or prescribing provider if the medication prescribed can cause photosensitivity.

2. Avoid the Sun: Try to stay out of direct sunlight as much as possible for at least two days after starting treatment with photosensitive medications.

3. Cover Up: When you do go outside, wear long sleeves, pants and a wide-brimmed hat to protect your skin from the sun’s rays. Use sunblock.

4. Be Cautious Indoors: Avoid bright indoor lights after applying any photosensitive creams to your skin, especially before light therapy.

Understanding Photosensitivity:

According to the FDA, photosensitivity can appear in two different ways: photoallergy and phototoxicity.

• Photoallergy: This is an immune response that occurs after the skin is exposed to sunlight and the medication, resulting in a rash or other skin changes.
• Phototoxicity: This is a direct reaction that happens quickly, causing symptoms like severe sunburn, even with minimal sun exposure.
