Side Effects of Galantamine

The most common side effects of galantamine that were seen in clinical studies include diarrhea, dizziness, vomiting, and nausea. Other, less common side effects (seen in less than 1 percent of people) include kidney stones, nosebleeds, and increased salivation. Although most galantamine side effects do not require medical attention, some should be reported to your healthcare provider immediately, including fainting, difficulty passing urine, and seizures.

 

Side Effects of Galantamine: An Overview

As with any medicine, side effects are possible with galantamine hydrobromide (Razadyne®); however, not everyone who takes the medication will experience side effects. In fact, many people tolerate it quite well. If side effects do occur, they are often minor and either require no treatment or can easily be treated by you or your healthcare provider.
