Cautions with other medicines
It's unlikely that other medicines commonly used to treat chronic obstructive pulmonary disease (COPD) or asthma will affect or be affected by tiotropium inhalers.
There are some medicines that can increase the chance of side effects if taken with tiotropium.
Always check with your doctor or a pharmacist before starting any new medicine while you're using tiotropium inhalers.
Mixing tiotropium with herbal remedies and supplements
There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with tiotropium. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
