Serevent Diskus Precautions
Serevent Diskus can cause serious side effects, including:
1. People with asthma who take long-acting beta2-adrenergic agonist (LABA) medicines such as Serevent Diskus, have an increased risk of death from asthma problems. It is not known if LABA medicines such as salmeterol xinafoate increase the risk of death in people with COPD. Call your healthcare provider if breathing problems worsen over time while using Serevent Diskus. You may need a different treatment.
Get emergency treatment if:
- breathing problems worsen quickly
- you use your rescue inhaler medicine, but it does not relieve your breathing problems
2. Do not use Serevent Diskus as your only asthma medicine. Serevent Diskus must only be used with a long-term asthma-control medicine, such as an inhaled corticosteroid. Serevent Diskus should be used only if your healthcare provider decides that your asthma is not well controlled with a long-term asthma control medicine, such as an inhaled corticosteroid. When your asthma is well controlled, your healthcare provider may tell you to stop taking Serevent Diskus. Your healthcare provider will decide if you can stop Serevent Diskus without loss of asthma control. You will continue taking your long-term asthma control medicine, such as an inhaled corticosteroid.
3. Children and adolescents who take LABA medicines may have an increased risk of being hospitalized for asthma problems.
Do not take Serevent Diskus:
- to treat your asthma without an asthma medicine known as an inhaled corticosteroid
- if you are allergic to Serevent Diskus or any of the ingredients in Serevent Diskus
- if you have a severe allergy to milk proteins. Ask your healthcare provider if you are not sure.
Serevent Diskus Food Interactions

Tell your healthcare provider about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.
Serevent Diskus and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. No well-controlled studies have been done in humans. It is not known if Serevent Diskus may harm your unborn baby. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Instructions for Using Serevent Diskus:
Follow the instructions below for using your Serevent Diskus. You will breathe in (inhale) the medicine from the Diskus. If you have any questions, ask your healthcare provider or pharmacist.
Take the Serevent Diskus out of the box and foil pouch. Write the “Pouch opened” and “Use by” dates on the label on top of the Diskus. The “Use by” date is 6 weeks from date of opening the pouch.
- The Diskus will be in the closed position when the pouch is opened.
- The dose indicator on the top of the Diskus tells you how many doses are left. The dose indicator number will decrease each time you use the Diskus. After you have used 55 doses from the Diskus, the numbers 5 to 0 will appear in red to warn you that there are only a few doses left.
Taking a dose from the Diskus requires the following 3 simple steps: Open, Click, Inhale.
1. OPEN - Hold the Diskus in one hand and put the thumb of your other hand on the thumbgrip. Push your thumb away from you as far as it will go until the mouthpiece appears and snaps into position.
2. CLICK - Hold the Diskus in a level, flat position with the mouthpiece towards you. Slide the lever away from you as far as it will go until it clicks. The Diskus is now ready to use.
Every time the lever is pushed back, a dose is ready to be inhaled. This is shown by a decrease in numbers on the dose counter. To avoid releasing or wasting doses once the Diskus is ready:
- Do not close the Diskus.
- Do not tilt the Diskus.
- Do not play with the lever.
- Do not move the lever more than once.
3. INHALE - Before inhaling your dose from the Diskus, breathe out (exhale) fully while holding the Diskus level and away from your mouth. Remember, never breathe out into the Diskus mouthpiece.
Put the mouthpiece to your lips. Breathe in quickly and deeply through the Diskus. Do not breathe in through your nose.
Remove the Diskus from your mouth. Hold your breath for about 10 seconds, or for as long as is comfortable. Breathe out slowly.
The Diskus delivers your dose of medicine as a very fine powder. Most patients can taste or feel the powder. Do not use another dose from the Diskus if you do not feel or taste the medicine.
4. Close the Diskus when you are finished taking a dose so that the Diskus will be ready for you to take your next dose. Put your thumb on the thumbgrip and slide the thumbgrip back towards you as far as it will go. The Diskus will click shut. The lever will automatically return to its original position. The Diskus is now ready for you to take your next scheduled dose, due in about 12 hours.
- Never breathe into the Diskus.
- Never take the Diskus apart.
- Always ready and use the Diskus in a level, flat position.
- Do not use the Diskus with a spacer device.
- Never wash the mouthpiece or any part of the Diskus. Keep it dry.
- Always keep the Diskus in a dry place.
- Never take an extra dose, even if you did not taste or feel the medicine.
Serevent Diskus Dosage
The usual dosage for adults and children aged 4 years and older is 1 inhalation (50 mcg) twice daily (morning and evening, approximately 12 hours apart).
For maintenance treatment of bronchospasm associated with COPD, the dosage for adults is 1 inhalation (50 mcg) twice daily (morning and evening, approximately 12 hours apart).
One inhalation of Serevent Diskus at least 30 minutes before exercise has been shown to protect patients against EIB.
Do not use extra Serevent Diskus before exercise if you already use it 2 times each day.
Serevent Diskus Overdose
If you take too much this medication, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.
If this medication is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.
- Store Serevent Diskus at room temperature between 68°F to 77°F (20°C to 25°C). Keep in a dry place away from heat and sunlight.
- Safely discard Serevent Diskus 6 weeks after you remove it from the foil pouch, or after the dose indicator reads “0”, whichever comes first.
- Keep salmeterol and all medicines out of the reach of children.
Serevent Diskus FDA Warning
Long-acting beta2-adrenergic agonists (LABA), such as salmeterol, the active ingredient in SEREVENT DISKUS, increase the risk of asthma-related death. A US trial showed an increase in asthma-related deaths in subjects receiving salmeterol (13 deaths out of 13,176 subjects treated for 28 weeks on salmeterol versus 3 out of 13,179 subjects on placebo). Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA.
Prescribe SEREVENT DISKUS only as additional therapy for patients with asthma who are currently taking but are inadequately controlled on a long-term asthma control medication, such as an inhaled corticosteroid. Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (e.g., discontinue SEREVENT DISKUS) if possible without loss of asthma control and maintain the patient on a long-term asthma control medication, such as an inhaled corticosteroid. Do not use SEREVENT DISKUS for patients whose asthma is adequately controlled on low- or medium-dose inhaled corticosteroids.
Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients.
