What it is used for
- Chronic obstructive pulmonary disease (COPD)
- Long-term control of breathlessness and wheeze in COPD
- Reducing COPD flare-ups
- Some cases of difficult asthma, as an add-on under specialist guidance
How it works
Tiotropium keeps the airways open for a long time by blocking the nerve signals that tighten the muscle around them. It is taken regularly to prevent breathlessness, not for instant relief.
How it is taken
Used as a once-daily inhaler (a dry-powder device or a soft-mist inhaler). It is breathed in and taken regularly at the same time each day. It is a long-term controller, not a fast reliever. Use it exactly as your clinician directs.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
Common side effects
- Dry mouth
- Throat irritation, cough, or hoarseness
- Constipation
- Headache
- Sinus or throat infections
Serious effects — get help
- Eye pain, blurred vision, or seeing halos (possible glaucoma — seek urgent care)
- Difficulty passing urine
- Signs of a severe allergic reaction (swelling, breathing difficulty)
- Sudden wheeze or breathing difficulty straight after use
If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.
Interactions to watch
- Other anticholinergic medicines (added drying effects)
- Other inhaled COPD/asthma medicines (often used together, but tell your clinician)
Who should take care
- Avoid getting the powder or mist in your eyes
- Caution with glaucoma, an enlarged prostate, or difficulty passing urine
- Caution with kidney problems
- Tell your clinician if you are pregnant, planning pregnancy, or breastfeeding
- It is not a reliever — keep a fast-acting inhaler for sudden symptoms
