Question 1

Can Fostair cause weight gain?

Accepted Answer

Weight gain is not a common side effect at inhaled doses. If you experience unexplained weight gain, especially with facial rounding, it could indicate adrenal suppression – consult your doctor.

Question 2

Does Fostair affect the heart?

Accepted Answer

Formoterol can cause palpitations, tachycardia, or rarely arrhythmias, especially in susceptible individuals. If you have pre‑existing heart disease, your doctor will assess the balance of risks.

Question 3

What should I do if I get oral thrush from Fostair?

Accepted Answer

Rinse your mouth thoroughly after each use, and use a spacer. Your doctor can prescribe antifungal treatment (e.g., nystatin). Do not stop Fostair without advice.

Question 4

Can I drink alcohol while using Fostair?

Accepted Answer

There is no direct interaction, but alcohol may increase the risk of certain side effects like dizziness or palpitations. The small amount of ethanol in Fostair itself is negligible. Moderate drinking is unlikely to cause problems.

Question 5

Are Fostair side effects permanent?

Accepted Answer

Almost all side effects are reversible once the medicine is stopped or the dose adjusted. Very long‑term high‑dose use may cause cataracts or glaucoma, which can persist, but these are rare.
