Common Galantamine Side Effects
Galantamine has been studied thoroughly in clinical trials. In these clinical trials, one group of people was given the real medication, while another group was given a placebo (a "sugar pill" with no active ingredients). This way, it is possible to see what galantamine side effects occurred, how often they appeared, and how they compared to the group who took the placebo.
In these studies, the most common side effects of galantamine included:
- Nausea -- in up to 24 percent of people
- Vomiting -- up to 13 percent
- Diarrhea -- up to 9 percent
- Dizziness -- up to 9 percent
- Loss of appetite -- up to 9 percent
- Headaches -- up to 8 percent
- Urinary tract infections (UTIs), such as bladder infections -- up to 8 percent.
Other common galantamine side effects, occurring in 2 to 7 percent of people, included:
- Fatigue
- Shakiness
- Abdominal pain (stomach pain)
- Indigestion or heartburn
- Weight loss
- Insomnia
- Drowsiness
- Anemia
- Runny or stuffy nose.
Less Common Side Effects of Galantamine
There are other, less common galantamine side effects that can occur. In studies, these side effects occurred in less than 1 percent of people taking the drug. For these side effects, it is difficult to tell whether they are actually caused by galantamine or something else. There is a good chance that these "side effects" could be completely unrelated to galantamine.
These less common potential galantamine side effects include, but are not limited to:
- A spinning sensation (vertigo)
- Leg cramps
- Ringing in the ears (tinnitus)
- Increased salivation
- High blood sugar
- Nosebleeds
- Increased libido (sex drive)
- Kidney stones.
