Reilly Special labels are often attached to the medicine containers of those drugs that have photosensitive properties within them. There are several reactions that can occur. However, the most common reaction is an intense or exaggerated sunburn, but rashes, blistering, swelling and other skin problems can also occur. 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. It must be also noted that in some cases, photosensitivity may also continue after a drug is stopped. With tetracycline for example, some people stay sensitive for several weeks.
