Montelukast is a prescription drug that treats allergic rhinitis and asthma. This asthma prescription drug is a leukotriene receptor antagonist medication. Montelukast's effectiveness is the result of its ability to bind with leukotriene receptors in your airway. 

HealthTap can help you get an asthma prescription online by connecting you with a primary care doctor who can provide advice and treatment as your online asthma doctor. Montelukast may be prescribed for the following issues: 

You can find montelukast under the brand name Singulair. It is used in both adults and children, and is available from in-person and  online asthma doctors. 

Dosage and Metabolism

Montelukast sodium comes in a powdered form and is water-soluble. You can find chewable montelukast tablets in 4mg and 5mg strengths, whereas the film-coated tablets are available in 4mg and 10mg sizes. 

Typically, you must take montelukast once a day. However, it is up to your doctor to determine the right dosage and formula based on your medical condition and symptoms.

Primary care doctors who know their patients well can be their best doctors for asthma, especially when patients want to be evaluated for online asthma prescriptions. One’s doctor will be able to gauge one’s asthma and allergies, and then advise on which medications to use and what follow-up care is needed. 

You can take montelukast orally before or after eating, or as directed by your doctor. Dosage may be based on your medical condition and age. If taking chewable tablets, one should chew each tablet thoroughly before swallowing.

What if one happens to miss a dose? In that case, one may take the dose later during the same day. There’s usually no need to take the missed dose if the missed dose was during a prior day.

If you are taking montelukast, you should try to avoid certain activities and situations that may trigger the next asthma attack. If your asthma symptoms worsen when you take aspirin, you should avoid taking aspirin or any other non-steroidal anti-inflammatory drugs, including naproxen, ibuprofen, diclofenac, celecoxib, meloxicam, etc., unless advised otherwise by your doctor. 

Precautions before Taking Montelukast

Before you get an asthma prescription online or through your local clinic, you should inform the doctor or pharmacist about any allergies you may have. Some people may even be allergic to montelukast.

You should also share your medical history with your online asthma doctor or your in-person doctor. This becomes even more important if you have a medical history of liver disease, anxiety, depression, suicidal thoughts, or other mental health issues. 

In case you experience any allergic reaction, such as severe itching, hives, difficulty breathing, blisters, or swelling of lips, face, throat, or tongue, it would be best if you call your emergency services number such as 911.

Some patients with asthma with new or old mental health issues should speak to their primary care doctor first before taking montelukast. Even after an online asthma doctor's advice, if you feel an unusual change in your behavior and mood, speak to the doctor again. Some possible side effect symptoms to note while using montelukast are: 

  • Anxiety

  • Confusion  

  • Memory or concentration issues

  • Aggression

  • Agitation

  • Feeling irritable or restless

  • Having suicidal thoughts

  • Repetitive or compulsive behavior

  • Stomach pain

  • Diarrhea

  • Sleeping issues, sleepwalking, or hallucinations

  • Tremors, stuttering, or uncontrolled movement of the muscles

The list is not complete; you can see the complete list of possible side effects of montelukast on the FDA website
