How can this medicine affect other medicines?

It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.

This medicine should not be taken with beta-blockers, such as atenolol, propranolol or timolol. This is because beta-blockers have an opposite action to this medicine and cause the airways to narrow. This can result in breathing difficulties for people with asthma or COPD. This problem has sometimes been seen with eye drops containing beta-blockers, eg used for glaucoma.

Salbutamol can potentially cause a serious decrease in the levels of potassium in the blood (hypokalaemia), which may result in adverse effects. This effect can be increased by the following medicines, which can also lower potassium in the blood:

xanthine derivates, such as theophylline or aminophylline

corticosteroids, such as beclometasone and prednisolone

other beta 2 agonists, such as salmeterol

diuretics, such as bendrofluazide and frusemide.

This is why people with severe asthma or COPD, who may be taking several of these medicines, should have their blood potassium levels monitored regularly.
