The symptoms of photosensitivity are potentially severe, though thankfully they are rare. The most common side effects associated with taking antibiotics in high doses and photosensitivity are blisters, swelling and hives. The good news is that in many cases the symptoms associated with photosensitivity begin to subside within 2 to 7 days of discontinuing treatment; however you should never interrupt your therapy without first speaking to a medical professional. When you receive your treatment make sure you always read the patient leaflet, so you are aware of any possible contraindications and side effects.
People who should take particular care are those who opt to take doxycycline as their preferred anti-malarial treatment. Malaria is a contagious disease which is found prevalently in hot, tropical climes, so a lot of sun exposure is to be expected if you travel to those areas of the world affected by malaria. In addition, as one of the cheapest anti-malaria prophylaxis treatments around, doxycycline is the medication of choice for those who wish to travel for long periods of time. The combination of these factors increases the risk of side effects meaning it is vital that measures to protect the skin be followed carefully. With anti-malarial medicines it is extremely important you do not stop taking your medications and that you speak to a doctor immediately following the appearance of symptoms.
Anyone put on a course of antibiotics who anticipates spending time in the sun is advised to speak to their doctor. Your doctor may wish to change the kind of medicine prescribed or may simply want to discuss any measures you should adopt in order to minimise the risk of sun damage. It is likely your doctor will advise you to avoid sun exposure during the entire period you are to be treated or that they will suggest you use a high factor sunblock to prevent UV rays from penetrating the skin. The best sunscreens are ones containing zinc oxide or titanium dioxide. Following just a few simple points will go a long way to avoiding the risks of skin damage and will allow you to successfully complete your course of antibiotics.
