MEDICATION AND SUN: WHAT ARE THE RISKS?

essential to heed their advice. Certain drugs are considered photosensitive, meaning they can increase your skin’s sensitivity to sunlight or potentially lead to an allergic reaction when exposed to the sun. This reaction could be categorized as a type of sun allergy or a sun-induced allergic response. Let’s delve deeper into this matter.

PHOTOTOXICITY: A RAPID REACTION

When your skin absorbs ultraviolet radiation from the sun, it can interact with certain medications present in the blood vessels near the skin’s surface. When activated by UV rays, these medications can harm skin cells, leading to a reaction resembling sunburn.

This phototoxic reaction occurs swiftly. Sun-exposed skin becomes red, hot, and painful, resembling a severe sunburn that appears disproportionate to the actual sun exposure time. In more severe instances, skin blisters can develop.

PHOTOALLERGY: A DELAYED REACTION

Exposure to UV rays from the sun can lead to an immune system reaction when combined with certain medications. This is referred to as a photoallergic reaction, which is less frequent than phototoxic reactions. It is typically associated with products applied directly to the skin, such as medicated creams or perfumes.

A photoallergic reaction typically manifests one to three days after sun exposure and may resemble hives or eczema. In severe cases, it can extend beyond the sun-exposed area.

THE MOST COMMON PHOTOSENSITIVE DRUGS

Several over-the-counter and prescription medications have been associated with instances of phototoxic or photoallergic reactions. These include:

  • Certain antibiotics
  • Some antidepressants
  • Diuretics
  • Hormonal contraceptives
  • Certain medications for heart disease
  • Non-steroidal anti-inflammatory drugs (pain relievers)
  • Antihistamines
  • Acne medications

YOUR PHARMACIST IS THERE FOR YOU

Your pharmacist can inform you about whether your medication might increase your sun sensitivity. While the likelihood of encountering a photoallergic or phototoxic reaction is quite low, they can generally be avoided by following proper sun protection practices, gaining the right knowledge, and preventing heat-related issues.

For individuals at greater risk, like those with specific skin conditions, the pharmacist may recommend an alternative medication.

If you suspect you’re experiencing a sun-related reaction, consult with your healthcare provider.

When considering an over-the-counter medication or natural health product, always read the package warnings carefully or consult your pharmacist.
