Serevent (Salmeterol) Dosage and Side Effects

SEREVENT inhalation is used to prevent asthma attacks or exercise-induced bronchospasm. SEREVENT inhalation is also used to treat chronic obstructive pulmonary disease (COPD) including emphysema and chronic bronchitis.

Proper Use of this medication

SEREVENT may increase the risk of asthma-related death. Use only the prescribed dose of this medication, and do not use it for longer than your doctor recommends. Follow all patient instructions for safe use. Tell your doctor if your symptoms do not improve after 1 week of treatment.

Do not use SEREVENT inhalation to treat an asthma attack that has already begun. It will not work fast enough. Use only a fast-acting inhalation medication.

Asthma is often treated with a combination of different drugs. If you use SEREVENT inhalation to treat asthma, you must use it together with another asthma control medication. Use all of your medications as directed by your doctor. Talk with your doctor if your medications do not seem to work as well in treating or preventing attacks. Do not change your doses or medication schedule without advice from your doctor.

Serevent Diskus is a powder form of SEREVENT inhalation that comes with a special inhaler device preloaded with blister packs containing measured doses of the medicine. The device opens and loads a blister each time you use the inhaler. This device is not to be used with a spacer.

Use SEREVENT inhalation regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.

Do not stop using SEREVENT inhalation without first talking to your doctor. Your asthma symptoms may get worse after you stop using the medication.

If you also use a steroid medication, do not stop using the steroid suddenly or you may have unpleasant withdrawal symptoms. Talk with your doctor about taking less and less of the steroid before stopping completely.

Seek medical attention if you think any of your asthma medications are not working as well as usual. An increased need for medication could be an early sign of a serious asthma attack. If you use a peak flow meter at home, call your doctor if your numbers are lower than normal.

Store at room temperature away from moisture, heat, and sunlight.

Do not try to clean or take apart the Diskus device. Throw it away 6 weeks after you have taken it out of the foil pouch, or if the dose indicator shows a zero, whichever comes first. Each Diskus device contains 60 doses.

Seek emergency medical attention or call the Poison Help line.

Use the medication as soon as you remember, then wait 12 hours before using the medication again. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

Side Effects

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • worsening asthma symptoms, or other breathing problems after using this medication;
  • muscle cramps, sleep problems (insomnia), tremors;
  • chest pain, fast or irregular heartbeats, feeling light-headed, fainting, or seizure (convulsions);
  • low potassium (confusion, uneven heart rate, extreme thirst, increased urination, leg discomfort, muscle weakness or limp feeling); or
  • high blood sugar (increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, weight loss).

Common side effects may include:

  • headache;
  • flu symptoms;
  • joint or muscle pain;
  • throat irritation, cough; or
  • stuffy or runny nose.

Warnings and Precautions

Do not use SEREVENT inhalation to treat an asthma attack that has already begun.

SEREVENT may increase the risk of asthma-related death. Use only the prescribed dose of this medication, and do not use it for longer than your doctor recommends. Follow all patient instructions for safe use. Talk with your doctor about your individual risks and benefits of using SEREVENT inhalation.

If you use SEREVENT inhalation for asthma, you must use it together with another long-term asthma control medication. Seek medical attention if you think any of your asthma medications are not working as well as usual.

To make sure SEREVENT inhalation is safe for you, tell your doctor if you have:

  • a food or drug allergy;
  • heart disease or high blood pressure;
  • epilepsy or other seizure disorder;
  • diabetes;
  • a thyroid disorder; or

It is not known whether SEREVENT inhalation will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
