Overview
It combines a steroid (fluticasone) and a long-acting bronchodilator (salmeterol).
It doesn't work fast enough for a sudden attack. Keep a rescue inhaler too.
What it's used for
- Asthma that isn't controlled with a steroid inhaler alone
- COPD
How to take it
- Use it twice a day, about 12 hours apart, every day, even when you feel well.
- Rinse your mouth with water and spit after each use to prevent thrush.
- Don't use it more than twice a day.
Your dose depends on your health and other medicines. Always follow your prescription label, and ask your pharmacist if anything is unclear.

Warnings

Other medicines, foods, and alcohol

Tell your provider and pharmacist about every medicine, vitamin, and supplement you take.
Pregnancy and breastfeeding
Controlling asthma is important in pregnancy. Talk with your provider.
