What is Serevent?

Serevent is a medication for treating asthma described as a long-acting reliever. It has a long-acting effect on symptoms and can last for over 12 hours in some cases. When administered, the medication takes around 10-20 minutes for its effects to kick in.

The medication can be taken in two types of devices. One is called an Evohaler, which contains a canister and works similarly to a conventional inhaler. Alternatively, there is the Accuhaler, which administers the medicine in powder form. Whatever form it’s taken in, the main goal of Serevent is to help avoid breathing problems and prevent asthma attacks which could potentially be triggered by exercise or other factors.

How does Serevent work?

The functioning component in Serevent is called salmeterol, which makes slight alterations to the immune system - the catalyst for asthma symptoms. When someone with asthma is exposed to irritants or other triggers for their condition, the immune system releases a chemical in response that causes inflammation in the bronchi, the small pipes connecting the lungs to the trachea (windpipe). Following this inflammation, the surrounding muscle walls tense up, narrowing the airways. An increase in the production of phlegm is another potential response which hinders breathing further.

Salmeterol acts on beta-2 receptors which are involved in this immune system response in the bronchi. By disrupting these receptors, the medicine is able to relax muscle walls in the affected area and allows narrowed airways to dilate, encouraging smoother breathing and relieving symptoms.

How do I take Serevent?

The exact instructions on taking Serevent vary depending on whether you are taking it through an Evohaler or an Accuhaler. Your doctor, nurse or pharmacist should provide instructions on how to use your inhaler properly and your product’s information leaflet should include a thorough explanation too. Your leaflet will also contain guidance on how to properly clean and maintain your inhaler.

When taking Serevent with an Evohaler, the usual dose for adults and adolescents aged 4 years and above is two puffs twice a day. For those aged 12 or older who have more severe asthma, your doctor may increase the dose to 4 puffs twice a day.

When using an Accuhaler for this medication, the usual starting dose for adults and children aged 4 or above is one puff twice a day. For those aged 12 or older with stronger asthma symptoms, the dose may be increased by your doctor to two puffs twice a day. When you have just finished using your Evohaler or Accuhaler, it is best to clean the mouthpiece right away using a dry cloth or tissue.

What are the side effects of Serevent?

When taking Serevent with either an Evohaler or Accuhaler, various side effects could be experienced, although not every patient will experience any. The most common side effects reported by users of this medicine are:

  • Muscle cramps
  • Feelings of shakiness
  • Fast or even heartbeat (palpitations)
  • Headaches

These side effects usually do not last long and are less likely to happen over time as treatment with Serevent continues. Other side effects are possible but also much rarer. If you do experience any side effects, then it is best to contact your doctor or pharmacist as soon as you can, particularly if the effects are causing great discomfort. In very rare cases, using this medication can cause breathing difficulties and wheezing to get worse straight away. If this happens, stop taking this medication and use your fast-acting reliever inhaler to help your breathing and get in touch with your doctor straight afterwards.

Can I use Serevent?

Serevent may be prescribed while you’re taking other medications to treat asthma. This other medicine, which could include a steroid inhaler or steroid tablets, should continue to be used. Continue to take the same doses of these other medicines as before, unless instructed otherwise by your doctor.

Your doctor may want to check your health regularly if you have certain health issues and wish to use this medication. Inform your doctor before starting Serevent if you have any of the following conditions:

  • An overactive thyroid gland
  • Diabetes mellitus (this medication may increase your blood sugar)
  • Heart disease, including a fast or irregular heartbeat

You should also speak to your doctor prior to taking Serevent if you are taking (or have recently used) any other medicines. That includes other treatments for asthma or any medication acquired without a prescription. Certain medicine may not be suitable to take at the same time as Serevent, including the following:

  • Medicines for fungal infections which contain ketoconazole or itraconazole
  • Ritonavir (for treating HIV)
  • Beta-blockers such as atenolol, propranolol and sotalol
  • Diuretics (water tablets) such as theophylline and steroids that treat high blood pressure

What if I take too much Serevent?

If you accidentally take more of this drug than recommended, then talk to your doctor or pharmacist. You may experience side effects such as an abnormal heartbeat and feelings of shakiness or dizziness. Other possible side effects include muscle weakness, aching joints and headaches.

What if I forget to take Serevent?

If you forget to take a dose of this medication on any particular day, then just wait to take the next dose at the usual time. Don’t ever take a double dose to compensate for a missed one.
