Nicotine Gum Side Effects

Although most people do not experience problems with nicotine gum, side effects are possible and may include belching, irritability, and nausea, among others. In most cases, reactions to this gum tend to be minor and easily treated. However, notify your healthcare provider right away if you experience more serious problems, such as a severe jaw ache, mouth ulcers, or unexplained swelling.

Just like any medicine, nicotine gum (Nicorette® Gum) can cause side effects. However, not everyone who uses the medication will have problems. In fact, most people tolerate it quite well.
