Salmeterol is used to treat asthma and other lung-related problems.

Salmeterol is a bronchodilator which means that it works by opening up the air passages in the lungs so that air can flow into the lungs more freely. This helps to control the symptoms of asthma and COPD, such as coughing, wheezing and shortness of breath.

If you have asthma, salmeterol will be used alongside a regular inhaled corticosteroid treatment (also called 'steroid' or 'preventer' inhalers). Some salmeterol inhalers already contain a corticosteroid.

Salmeterol takes longer than some other bronchodilator inhalers to have an effect. This means that this inhaler is not suitable for the relief of an acute asthma attack.

Before using salmeterol make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have hyperthyroidism (an overactive thyroid gland).
  • If you have heart problems.
  • If you have hypertension (high blood pressure).
  • If you have diabetes.
  • If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
  • If you have ever had an allergic reaction to this or to any other medicine.
  • Before beginning treatment, read the manufacturer's printed information leaflet to make sure you understand how to use your inhaler.
  • Use salmeterol exactly as directed by your doctor. Use the inhaler regularly, but do not use it more often than you have been told to. It is usually used twice each day unless you have been told otherwise by your doctor.
  • If you forget a dose, use the inhaler as soon as you remember and then carry on as before.
  • Salmeterol does not work quickly enough to relieve an asthma attack that has already started. If you have asthma, your doctor will prescribe another inhaler for you to use if you get an attack. Make sure that you keep it with you all the time.
  • If you use a corticosteroid (preventer) inhaler you should continue to use it even if salmeterol improves your symptoms.
  • If you do not feel that salmeterol is helping your breathing or if you feel it is making it worse, return to your doctor for advice.
  • Keep your regular doctor's appointments so your progress can be monitored. Your doctor or nurse may also want to check your technique to make sure you know how to use your inhaler correctly.
  • Do not smoke. Smoking causes severe irritation and damage to the lungs. It will make your condition worse and will reduce the beneficial effects of your medication.
  • If at any time you do not feel you are getting the same benefit as with a previous dose, or if your breathing gets worse, speak with your doctor or clinic as soon as possible.
  • Do not stop using salmeterol without speaking with your doctor first.
  • If you have diabetes you must check your blood glucose levels regularly as this preparation can affect the levels of sugar in your blood.
  • Keep your inhaler clean and free from any dust or particles which you could choke on.
  • If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking.
  • If you buy any medicines, check with a pharmacist that they are safe to take with your other medicines.

Along with their useful effects, all medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.

Possible side-effects What can I do if I experience this
Headache Ask your pharmacist to recommend a suitable painkiller. If the headache continues, speak with your doctor
Feeling sick Eat little and often. Stick to simple foods
Dizziness Make sure your reactions are normal before driving or operating machinery
Feeling shaky, nervousness, muscle cramps or pain, rash, and palpitations If troublesome, speak with your doctor or clinic

Important: if your breathing deteriorates speak with your doctor as soon as possible.

If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.
