One of my favorite columns on the New York Times is called “Really?” by Anahad O’Connor. It debunks common myths and sets the facts straight on everything from wives tales to doctor’s orders. Recently, they brought to attention something that we think is really important- and very misunderstood.
With the Spring approaching, it is time for all of us to get our game faces on and prepare for the vicious Colorado sun. However, (I sniffle as I write this….) coming out of the icky Winter, a lot of us are still fizzing the Alka Seltzer and finishing our remaining antibiotics from cold and flu season. And we have got to know the facts about photosensitivity and the medications that exacerbate it.
Here’s what O’Connor says:
“Most people know what precautions to take to protect their skin at the beach this summer: slather on the sunscreen, reapply as needed and take breaks in the shade as often as possible. But few people know that a number of common medications can intensify the effects of sunlight, greatly raising the risk of burning, rashes, and other skin problems, even after only a little time in the sun. Studies show that this can happen in at least two ways.
One, known as photoallergic reaction, occurs when a certain medicine or substance is applied to the skin. Ultraviolet light from the sun transforms the substance in a way that provokes the immune system, leading to irritated skin and eczema-like rashes. The onset of visible symptoms is usually delayed 24 hours to several days.
Far more common is a phenomenon called phototoxic reaction. It occurs when a person ingests the drug or substance in question, then spends time in the sun. Exposing the skin to ultraviolet rays excites molecules of the ingested substance, causing damage to tissue- severe redness and sunburn, for example – that is almost immediately apparent.
The list of drugs that can cause sensitivity is long, but among the most common culprits are antibiotics like tetracycline, certain antihistamines and topical antimicrobials. The best remedy is either to limit the use of the offending substance or to take extra precautions, like wearing protective clothing.
Bottom Line: Many drugs can raise a person’s sensitivity to sunlight.”
