Medication and the Sun

Dr. Anita Aderinkomi provides professional insight and practical tips to answer your medication questions
Member: I was recently prescribed antibiotics for bronchitis. My doctor said one of the side effects is photosensitivity and that I should be careful when spending time outside in the sun. What is that and how concerned should I be? — Danny, Princeton

Anita: Hi Danny, thank you so much for your question. Photosensitivity occurs when your skin becomes highly sensitive or has an abnormal reaction to UV or sunlight.

Drug-induced phototoxicity — the most common type of photosensitivity reaction — can be caused by oral or topical medication. When you have a phototoxic reaction, your skin may start developing a rash or look red like you have a sunburn. Photosensitive reactions can occur within minutes or hours of sun exposure.

It’s true that certain medications may cause you to be more prone to photosensitivity. Some of these medications include:

• NSAIDs like ibuprofen or aspirin
• Tetracycline antibiotics and fluoroquinolone antibiotics (used to treat a variety of bacterial infections)
• Retinoids
• Antidepressants
• Chemotherapy drugs
• Hydrochlorothiazide (commonly used totreat hypertension)

When taking medications that could increase your risk of photosensitivity,
it’s important to take precautions. Photosensitivity reactions can cause long-term damage to your skin and even increase your risk for skin cancer. Before you start taking a new medication, have a conversation with your healthcare provider about potential side effects like photosensitivity and phototoxicity.

There are several steps you can take to lower your risk. Limit your time in the sun during peak hours and seek shade when possible. It’s also important to use broad spectrum sunscreen. While SPF 15 works, SPF 30 or higher is preferred. Finally, consider wearing a wide brimmed hat and long sleeves that can protect your skin from the sun.
