All medicines can cause side effects and Sereflo is no different. You might not experience any, however it’s still good to know what to look out for. Headaches can be common, but these should improve as you continue your treatment. Thrush, sore throat or hoarse voice can also affect up to one in ten people. It’s recommended to rinse your mouth out or brush your teeth after using your inhaler to reduce this risk.
If your breathing gets worse after using Sereflo you may be having an allergic reaction so seek urgent medical attention immediately. You also need to use your fast-acting (blue) inhaler. Other reactions to look out for are itching, hives and swelling of the face, lips, tongue or throat. Tell your doctor as soon as possible if you get these – you’ll probably need to switch medication.
