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.
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.
(This article covers many, but not all, of the possible side effects with galantamine. Your healthcare provider can discuss a more complete list of galantamine side effects with you.)
Some side effects with galantamine, while usually infrequent, are potentially serious and should be reported immediately to your healthcare provider. These include, but are not limited to:
- A dangerously slow heart rate (bradycardia)
- Stomach ulcers or intestinal ulcers
- Difficulty passing urine
- Worsening of asthma
- Uncontrollable body movements or twitches
- Signs of an allergic reaction, including an unexplained rash, hives, itching, swelling of the mouth or throat, wheezing, or difficulty breathing.
