How Duonex 1 Tablet works

Warnings and precautions

Know which of your inhalers is the reliever and which is the preventer. A preventer must be used every day even when you feel well; a reliever is for symptoms. Seek emergency care if your reliever is not working, if you cannot speak a full sentence, or if you are using the reliever far more often than usual. Rinse your mouth with water and spit it out after every steroid inhaler dose to prevent thrush and hoarseness. Ask your doctor or pharmacist to watch your technique — poor technique is the commonest reason an inhaler seems not to work. Use a spacer if one has been advised, particularly for children.

Do not take Duonex if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for anyone with a known allergy to the propellant used in the inhaler.

Interactions with other medicines

Beta blockers, including eye drops for glaucoma, can tighten the airways and reduce the effect of your reliever.

How to store Duonex 1 Tablet

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Duonex 1 Tablet

Keep a spare reliever and check the counter so you are not caught with an empty one. Follow your written asthma action plan if you have one. Do not stop a preventer because you feel better — that is the medicine working.
