A warning said the skin can become sensitive to sunlight and the risk of burns can increase when taking some painkillers and antibiotics.
According to the Telegraph, a British daily, on the 8th (local time), the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) warned that some painkillers containing ibuprofen and naproxen can increase the skin's sensitivity to sunlight.
Methotrexate, used to treat arthritis, as well as some antibiotics and acne treatments, were also identified as drugs that can potentially cause photosensitivity.
The MHRA advised that while taking these drugs, people should drink enough fluids and, when exposed to sunlight, use clothing that covers the skin and sunscreen.
It added that some medicines not only heighten the skin's sensitivity to sunlight but can also affect the body's ability to cope with high temperatures.
Diuretics used to treat high blood pressure and heart disease can increase the likelihood of dehydration by promoting fluid excretion. Some antidepressants and antipsychotics are known to affect the body's temperature regulation.
