If you accidentally swallow a Spiriva HandiHaler capsule, you probably won’t have any side effects other than mild stomach discomfort. However, because the drug won’t reach your lungs, it won’t be able to work properly to treat your breathing condition.
By using the Spiriva HandiHaler device correctly, the drug inside the Spiriva capsules will be inhaled through your mouth into your lungs.
If you happen to swallow a Spiriva HandiHaler capsule, call your doctor or pharmacist. They can recommend whether you need to be seen by a healthcare provider.
