Let's take a minute to talk about your medication. 

This is Botox. Botox is injected into muscles to relax them. It can help improve several conditions, like overactive bladder, migraine headaches, and spasms in muscles such as eyelids, fingers, wrists, neck and head. It can also help reduce severe underarm sweating. Botox Cosmetic can help smooth wrinkles on the face. The effects of a Botox injection can last for several weeks to about 3 months. 

Most patients tolerate Botox well, but some side effects can happen. You could have mild pain at the injection site or in the area being treated. If it does not improve, or is bothersome, you should call your doctor. Other side effects can differ depending on the body part that is being treated. Your doctor will explain possible side effects and when to report them. For example, call your doctor right away if you have problems urinating after bladder treatment, or if you have blurry vision or drooping eyelids after injections near the eye. You should be careful driving until you know how the injections affect you. 

As with any medicine, rare but serious side effects could occur. With Botox, this includes allergic reactions. Symptoms could include skin changes like itching or a rash, or feeling faint or dizzy. It could also cause problems breathing or swallowing. You should get help right away if you notice these or other unusual changes to your body. 

It's important to tell your doctor about all of the medicines you take and have taken, even if they don't require a prescription. Also, check with your doctor and pharmacist each time you get a new medicine.
