Detrol Side Effects
Headache, dry mouth, and constipation are the most common side effects that have been reported with Detrol. Problems that are less common (occurring in 1 to 4 percent of people) include fatigue, diarrhea, and drowsiness. Certain side effects of Detrol, while occurring infrequently, are potentially serious and require immediate medical attention, such as difficulty passing urine, a fluttering sensation in your chest, and severe constipation.
As with any medicine, side effects are possible with Detrol® (tolterodine tartrate); however, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can be treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Detrol. Your healthcare provider can discuss a more complete list with you.)
Detrol has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to those that occur in another group of people not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common Detrol side effects included:
- Dry mouth -- in up to 35 percent of people (see Detrol and Dry Mouth)
- Headaches -- up to 7 percent
- Constipation -- up to 7 percent (see Detrol and Constipation)
- Dizziness or a spinning sensation (vertigo) -- up to 5 percent
- Abdominal pain (stomach pain) -- up to 5 percent.
Other common side effects, occurring in 1 to 4 percent of people, included:
- Chest pain
- Flu symptoms (such as fever, chills, or body aches)
- Indigestion or heartburn
- Painful urination
- Dry skin
- Joint pain
- Weight gain (see Detrol and Weight Gain)
- Dry eyes
- Problems focusing the eyes.
