Decongestant medication - Interactions 

Some decongestants also contain painkillers, such as paracetamol or ibuprofen. If you are already taking a painkiller for other symptoms, such as headaches or a fever, make sure you do not exceed the maximum dose when also taking a decongestant.

You should not take decongestants if you are taking a type of antidepressant called a monoamine oxidase inhibitor, as this can cause a dangerous rise in blood pressure.

Before starting to take any decongestant, make sure you check the patient information leaflets that come with your medicines, or see your GP or pharmacist for advice.
