Photosensitivity

What is photosensitivity?

Photosensitivity is when the skin becomes more sensitive to any type of light. Someone who is photosensitive will get a sunburn more easily and more severely than other people. Areas of the skin not exposed to the sun can even be affected. Photosensitivity can also cause lesions or a rash.

Some chemotherapy medications and radiation therapy treatments can cause photosensitivity. Other medications that can cause photosensitivity are certain antibiotics, some medications to control nausea and vomiting, and non-steroidal anti-inflammatory drugs (NSAIDs). People have different levels of sensitivity to sun exposure. Even if you have never been sensitive to the sun, you may be at risk now.

Chemotherapy-induced photosensitivity does not last forever, but it may take many weeks for it to go away. Radiation-induced photosensitivity is permanent. Areas of the skin that were in the radiation treatment fields will always be more sensitive to the sun.

How is it treated?

The best way to lower the effects of photosensitivity is to not go in the sun. If you need to be in the sun, you should:

• Put on sunscreen/sunblock often. Make sure you put sunscreen on areas that have lost hair, such as your eyebrows. Follow the package instructions for how often you should reapply.
• Use sunscreen lip block.
• Wear long-sleeved shirts, long pants, a hat, and sunglasses.
• Avoid perfumes and other chemical products on your skin. These may make your skin more sensitive.

If you get a sunburn, use cool compresses on the burned areas to cool the skin and help with pain. Your care provider may also prescribe pain and topical (placed on your skin) medications to help the itching or burning.

When should I call my care team?

• A severe sunburn that blisters or causes open sores.
