Beware Of Sunburn Boosters

(WebMD)  It was a day outdoors like many others and you had slathered on the sunscreen only to end up with a wicked sunburn. What went wrong? The answer may lurk in your medicine cabinet. Certain drugs and other substances can increase the skin's sensitivity to ultraviolet light and cause the skin to burn in less time or at a lower intensity of sunlight than it would normally.

Sunburn is a serious matter. Exposure to the sun's ultraviolet (UV) rays is a known risk factor in skin cancer skin cancer. The American Cancer Society estimates there will be 59,940 new cases of melanoma, the most serious form of skin cancer, in 2007. The death rate has increased 50% since 1973. WebMD talked with two experts about medications that heighten your risk for sunburn and how to stay safe in the sun.

The Leading Culprits

• Diuretics.Hydrochlorothiazide (HCTZ) is a commonly used diuretic ("water pill") used to treat high blood pressure high blood pressure . Combination drugs, which contain HCTZ, include Maxide, Dyazide, Hyzaar, and Zestoretic.


• Antibiotics. Tetracycline drugs, which include Sumycin, Tetracyn, and Vibramycin, are used to treat bacterial infections. Quinolone drugs like Cipro, which gained attention during the anthrax scare, and sulfa drugs, such as Bactrim, also heighten sun sensitivity. Cipro and Bactrim are antibiotics often used for urinary tract infections.


• Skin care products. Retin-A, alpha hydroxy acid, and microdermabrasion products used to minimize wrinkles and improve skin tone make the skin more susceptible to sun damage.


• Heart medications. Amiodarone, marketed under the brand name Cordarone, is used to treat abnormal heart rhythms.


• Diabetes Diabetes medications. Glipizide, sold also under the brand name Glucotrol, is an oral medication for type 2 diabetes. Other related drugs include Amaryl and glyburide.


• NSAIDs (nonsteroidal anti-inflammatory pain drugs). NSAIDs include over-the-counter pain relievers such as Advil, Aleve, Motrin, and the prescription drug Celebrex.


• Balsam of Peru. This herbal ingredient is often used in perfumed products and aftershave lotions.

Shedding Light on the Subject

Heightened sensitivity to sun, or a phototoxic reaction, occurs when ultraviolet rays interact with certain chemicals in medications. Even after you have stopped taking a drug, its effects may linger. "Depending on the type of drug and how long you've been taking it, it can remain in your system from one to five days," says Bill Bailey, RPh, director of specialized care centers for Medicine Shoppe in St. Louis. "To be on the safe side, always ask the pharmacist about the effects of your medications on sun exposure. They'll go online and get current, accurate information," he says.

You don't even have to go out in the sun to experience the complications of medications. You could easily get sunburned in a tanning salon, says dermatologist Craig Eichler, MD. "There have been some bad cases. Tanning booths primarily emit UVA rays, and that's what medications mainly interact with."

And here's another little-known fact about UV rays: They penetrate water. "Swimmers don't realize they can get sunburned under water," says Eichler. Water also reflects UV rays, which can add to your exposure.

SPF, UVA, UVB, and Some Good News

There's a debate over whether sunscreens with high SPF ratings provide any more protection than one rated SPF 15. "I recommend SPF 15. The stronger sunscreens often give people a false sense of security," says Bailey.

Eichler says SPF 15 blocks 92% of UVB rays, while SPF 30 blocks 97%.
"SPF 15 is fine for going to and from the store, but use SPF 30 for longer sun exposure or if you're taking medications."

Whether you use sunscreens with SPF 15 or 45 ratings, you're buying protection from UVB rays, says Eichler, who is with The Cleveland Clinic Florida in Naples. For protection against UVA rays, a product must contain one of the following active ingredients: zinc oxide, titanium dioxide, or avobenzone (Parsol 1789). "A problem is that these ingredients aren't stable for a very long time."

That's one reason he's glad to see that the FDA has just approved ecamsule, a broad-spectrum sunscreen that has been marketed since 1993 as Mexoryl SX in Europe and Canada. It protects against both UVA and UVB rays and has an SPF 15 rating. It is expected to become available in the U.S. over the counter sometime in the fall as Anthelios SX.

Protecting Yourself

Eichler recommends reapplying sunscreen every couple of hours and making sure to use enough. "Most people use at best half of what they need. If you put it on too thin, it doesn't give you protection." The American Cancer Society says the average adult should use about a palm-full of sunscreen to cover the arms, legs, neck, and face.

The key to effective sunscreen use is to reapply it often. Bailey advises applying it one-half hour before you go into the sun, and every half hour you're exposed. "Sunscreen wears off when you're sweating or in the water. Remember to cover your hands and feet with sunscreen, too."

Both experts tell WebMD you can't rely on sunscreen alone. Wear a hat, cover up, and avoid reflected rays from sand, concrete, and metal, which can reach you even if you've blocked the sun with an umbrella. Also stay out of the sun during the peak hours of 10 a.m. to 3 p.m.

I took the Made from Earth Pure Aloe Face Treatment on a recent vacation to Barbados. I usually burn on my face, shoulders and arms. My skin is quite painful and I peel for two weeks after I get home, which is never a pretty sight.

This time, I applied the Pure Aloe Skin Treatment every evening after getting back to my hotel room. The first thing you notice is how immediately soothing it is. Also, my skin recovered more quickly the next day. I was done peeling within only a couple days after getting home, and had a great tan as well. I'm never going on vacation without this made from earth aloe again.

This is the shocking news to heard that diabetes medications can increase sensitivity to the sun, means more chances for sunburns. http://healthy-ojas.com/diabetes/diabetes-details.html

One they failed to mention is anti-allergy meds like Zyrtec and Benadryl

This is the first time I have heard of this and since diabetes medications belong to the drugs that can increase sensitivity to the sun, I am glad to have come across this news item.

If the FDA would stop protecting profits of Corporations and allow Mexoryl in our sun protection products like the rest of the world they would not be near the damage to Americans from the sun. The FDA is an outrage.
