Off-label uses

Doctors sometimes prescribe a medicine for a condition it is not officially licensed for. This is called off-label use. It is legal and common when there is good evidence it helps, and your doctor should explain why they are suggesting it.

Tiotropium is not commonly used off-label.

How it works

Tiotropium blocks acetylcholine receptors on the muscles around the airways. This keeps the airways relaxed and open for 24 hours, easing breathlessness.

Side effects

Like all medicines, Tiotropium can cause side effects, although not everyone gets them. Many are mild and ease after the first few weeks.

Common side effects

dry mouth
constipation
cough
headache
sore throat

Tell your doctor or pharmacist if these bother you or do not go away.

Serious side effects

These are rare. Call 111 or contact your doctor straight away if you get:

wheezing that gets worse straight after using the inhaler
eye pain, blurred vision or seeing halos
being unable to pee

Call 999 if you have signs of a serious allergic reaction, such as swelling of your lips, mouth, throat or tongue, or trouble breathing.

You can report any side effect to the Yellow Card scheme, run by the medicines regulator.

Stopping and withdrawal
