Side Effects of Tiotropium
Common Side Effects
Tiotropium has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group 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 side effects of tiotropium included:
- Upper respiratory infection (such as the common cold) -- in up to 41 percent of people
- Dry mouth -- up to 16 percent (see Spiriva and Dry Mouth)
- Sinus infection -- up to 11 percent
- Sore throat -- up to 9 percent
- Bladder infection (urinary tract infection or UTI) -- up to 7 percent.
Other common side effects (occurring in 1 to 6 percent of people) included:
- Abdominal pain (stomach pain)
- Indigestion or heartburn
- Muscle pain
- Yeast infection
- Stuffy or runny nose.

These rare side effects include but are not limited to:
