There are several reactions that can occur. However, the most common reaction is an intense or exaggerated sunburn. However there are frequently rashes, blistering, swelling and other skin problems which can also occur. This is all due to a person being photosensitive. It is important to note here that not everyone who takes these drugs has a reaction.
Many people have no problems, and others react only mildly.
It is known that photosensitivity is hard to predict, and just because someone else hasn't had a reaction doesn't mean it won't happen with you. It is also known that the same person can also respond in different ways at different times. Many factors enter into this. Here you must be warned-don't be fooled if you haven't reacted while taking one of these drugs in the past . Photosensitivity can still occur the next time around.
