What is the mechanism of action of montelukast (Singulair)?

Montelukast functions by diminishing inflammation in the airways, making breathing easier. This prescription works by inhibiting the production of specific naturally occurring substances, called leukotrienes, which are implicated in causing or exacerbating symptoms associated with asthma and allergies.

 

What purposes does montelukast (Singulair) serve?

Primarily, a Singulair prescription is employed for preventing or managing asthma symptoms. It can also be used before exercise to decrease the likelihood of bronchospasms and reduce the reliance on quick relief inhalers.

Additionally, a montelukast prescription is occasionally utilized to alleviate symptoms of allergic rhinitis and hay fever. However, it is recommended only when other safer medications prove ineffective or cannot be taken.

 

How should montelukast (Singulair) be administered?
If your doctor has prescribed Singulair for you, it will be available in tablet form (either chewable or to be swallowed) or as oral granules in a packet, typically prescribed for small children. All forms are meant to be taken orally.

Tablets, whether regular or chewable, can be taken with or without food. It is advisable to take the prescribed dosage at the same time daily to optimize the medication’s effectiveness.

For oral granules, they should not be chewed but can be dissolved in a teaspoon of cold or room temperature baby formula or breast milk before swallowing. They can also be mixed into soft foods like applesauce or ice cream.

However, it is crucial not to dissolve them in any liquids other than formula or breast milk, as it may affect the medication’s efficacy.

 

What are the potential side effects and risks associated with montelukast (Singulair)?

Common side effects of a montelukast prescription may include:

– Fever
– Headache
– Stuffy or runny nose
– Difficulty swallowing
– Dryness or sore throat
– Loss of voice
– Tenderness in the glands of the throat or neck

While these symptoms are generally considered normal, it is essential to consult your doctor if you encounter:

– Sinus pain or swelling
– Numbness, tingling, or shooting pain in the arms or legs
– Severe muscle weakness or fatigue
– Stuttering
– Uncontrollable muscle spasms

In rare cases, a serious allergic reaction to Singulair may occur, prompting immediate medical attention if you experience:

– Severe itching or swelling, especially in the face, throat, or tongue
– Severe dizziness
– Difficulty breathing
– Rashes or blemishes

Additionally, Singulair may, in some instances, lead to agitation, disorientation, irritability, depression, or suicidal thoughts or tendencies. If you or your child experiences these effects, it is crucial to promptly discuss them with your doctor for proper monitoring.

 

Who should avoid taking montelukast (Singulair)?

Individuals with a history of specific mental health conditions, such as chronic depression, suicidal tendencies, anxiety, or anger issues, may be at risk of exacerbating or intensifying their existing mental health symptoms.

Patients who are currently undergoing a reduction or cessation of oral steroid dosage should refrain from using a Singulair prescription, as this could potentially lead to conditions like Churg-Strauss syndrome or eosinophilia.

Pregnant or breastfeeding individuals should use montelukast only if absolutely necessary, as this medication has been observed to pass into breast milk. It is crucial to consult with your doctor before starting this medication during pregnancy, as it may pose potential harm to the child.
