Salmeterol Oral Inhalation: A Guide for Usage and Safety

Last Updated On:

Salmeterol Oral Inhalation

Asthma is a chronic respiratory condition that affects millions of people worldwide. Managing its symptoms effectively is crucial for maintaining a good quality of life. One of the medications commonly prescribed for long-term asthma management is Salmeterol, an oral inhalation medication. This article delves into the details of Salmeterol, covering its uses, how it works, proper usage, side effects, and more.

What is Salmeterol?

Salmeterol is a long-acting beta2-adrenergic agonist (LABA) used primarily to control and prevent asthma symptoms. It’s not a rescue medication, meaning it’s not used for immediate relief during an asthma attack, but rather for ongoing management.

How Does Salmeterol Work?

Salmeterol works by relaxing the muscles around the airways in the lungs. This relaxation helps to keep the airways open, making it easier to breathe. It achieves this by stimulating beta2 receptors in the lungs, which leads to the smooth muscle relaxation.

Indications for Use

Salmeterol is typically prescribed for:

  • Asthma: As part of a long-term treatment plan to control and prevent symptoms.
  • Chronic Obstructive Pulmonary Disease (COPD): To manage symptoms such as chronic bronchitis and emphysema.

When Not to Use Salmeterol

It’s important to note that Salmeterol should not be used as a monotherapy for asthma. It’s usually prescribed in conjunction with an inhaled corticosteroid. Using Salmeterol alone can increase the risk of severe asthma exacerbations and asthma-related death.

Proper Usage of Salmeterol

Correct usage of Salmeterol is crucial for its effectiveness. Here’s a step-by-step guide to using Salmeterol inhalation correctly:

Before You Start

  • Read the Instructions: Every medication comes with a detailed instruction leaflet. Make sure to read it thoroughly.
  • Prime the Inhaler: If you’re using a new inhaler or haven’t used it in a while, you’ll need to prime it. This typically involves shaking the inhaler and releasing a few test sprays into the air.

Daily Use

  1. Shake the Inhaler: Always shake the inhaler well before each use.
  2. Breathe Out Fully: Exhale as much air from your lungs as possible.
  3. Position the Inhaler: Place the mouthpiece into your mouth, sealing your lips around it.
  4. Inhale and Press: As you start to breathe in slowly, press down on the inhaler to release the medication.
  5. Hold Your Breath: Hold your breath for 10 seconds to allow the medication to settle in your lungs.
  6. Exhale Slowly: Breathe out gently and replace the cap on the inhaler.

Rinsing Your Mouth

After using Salmeterol, it’s important to rinse your mouth with water and spit it out. This helps to reduce the risk of developing oral thrush, a fungal infection that can occur with inhaled medications.

Dosage and Administration

Typical Dosage

The standard dosage for Salmeterol is one inhalation twice a day, approximately 12 hours apart. It’s essential to stick to this schedule to maintain consistent levels of the medication in your system.

Missed Dose

If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and resume your regular schedule. Don’t double up on doses to make up for a missed one.


In case of an overdose, seek emergency medical attention immediately. Symptoms of an overdose may include chest pain, irregular heartbeats, tremors, and feeling light-headed or faint.

Side Effects of Salmeterol

Like all medications, Salmeterol can cause side effects. While many people using this medication do not experience serious side effects, it’s important to be aware of the potential risks.

Common Side Effects

  • Headache: This is one of the most frequently reported side effects. It’s usually mild and can often be managed with over-the-counter pain relievers.
  • Throat Irritation: Some users may experience a scratchy or sore throat after using the inhaler.
  • Cough: A dry cough can occur, particularly right after using the inhaler.
  • Hoarseness: This is often due to the inhaled medication’s effect on the vocal cords.
  • Nervousness: Some people report feeling jittery or anxious, which is a common side effect of beta-agonists.

Serious Side Effects

While rare, serious side effects can occur. If you experience any of the following, seek medical attention immediately:

  • Chest Pain: This could indicate a serious heart problem.
  • Fast or Pounding Heartbeats: Known as palpitations, this side effect can be alarming and may require medical evaluation.
  • Severe Allergic Reactions: Symptoms can include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, and difficulty breathing.
  • Worsening Asthma Symptoms: Paradoxically, some patients might notice their asthma symptoms getting worse instead of better. This can be a sign of an adverse reaction to the medication.

Long-Term Side Effects

  • Osteoporosis: Long-term use of LABAs like Salmeterol, particularly when used with inhaled corticosteroids, can contribute to bone thinning.
  • Eye Problems: There have been reports of glaucoma and cataracts with long-term use, especially when combined with steroids.

Interactions with Other Medications

Salmeterol can interact with other medications, which may alter its effectiveness or increase the risk of serious side effects. It’s crucial to inform your healthcare provider of all the medications you’re taking, including over-the-counter drugs, vitamins, and herbal supplements.

Medications to Watch Out For

  • Beta-Blockers: These medications, commonly used to treat high blood pressure and heart conditions, can reduce the effectiveness of Salmeterol. Beta-blockers can block the receptors that Salmeterol targets, leading to reduced bronchodilation.
  • Diuretics: Also known as water pills, these can increase the risk of low potassium levels (hypokalemia), which Salmeterol can also cause. Low potassium levels can lead to muscle weakness, cramps, and even heart problems.
  • Antidepressants: Certain antidepressants, especially those in the class called tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs), can increase the risk of heart problems when used with Salmeterol. These interactions can lead to elevated blood pressure and heart rate.
  • Corticosteroids: Both inhaled and oral corticosteroids are often used in conjunction with Salmeterol for asthma treatment. While necessary for controlling inflammation, combining these medications can increase the risk of systemic side effects, such as osteoporosis and eye problems.
  • Other Long-Acting Beta Agonists: Using more than one LABA can increase the risk of experiencing side effects and is generally not recommended. Always follow your healthcare provider’s guidance on medication combinations.

Managing Side Effects and Interactions

Monitoring and Communication

  • Regular Check-Ups: Schedule regular visits with your healthcare provider to monitor your response to Salmeterol and adjust your treatment plan if necessary.
  • Blood Tests: Your doctor may recommend periodic blood tests to check for potential side effects, such as low potassium levels or changes in blood sugar levels.

Lifestyle Adjustments

  • Diet: Eating a balanced diet rich in potassium (like bananas, oranges, and leafy greens) can help counteract the potassium-lowering effects of Salmeterol.
  • Hydration: Staying well-hydrated can help manage some of the side effects, such as dry throat and cough.
  • Exercise: Regular physical activity can help improve overall health and may assist in managing asthma symptoms better.

Medication Management

  • Adherence to Prescribed Dosage: Always use Salmeterol exactly as prescribed. Do not increase your dose or frequency without consulting your healthcare provider.
  • Rinse Mouth After Use: To prevent oral thrush, rinse your mouth with water and spit it out after using the inhaler.
  • Emergency Plan: Have a clear action plan for asthma attacks, including the use of a rescue inhaler like albuterol, and know when to seek emergency medical attention.
