Buy Montelukast (Singulair) Online

Are you looking to buy Montelukast and other prescription medications for a fraction of what you usually pay? Buying medications with Canada Pharmacy Depot can save you up to 90% on the cost of Montelukast. It’s safe, convenient and quick from our Canadian pharmacy and you can order online or call us 7 days a week.

What is Montelukast?

Montelukast and the brand name Singulair are medications used to prevent wheezing and shortness of breath caused by asthma as well as to decrease the number of asthma attacks. Singulair may also be used to prevent breathing problems during exercise and can decrease the frequency that you need to use your rescue inhaler. Montelukast can also be used to relieve the symptoms of allergic rhinitis or hay fever. Montelukast works by blocking natural substances which can cause or worsen asthma and allergies and makes breathing easier by reducing inflammation in the airways.

Always read the patient information and instructions carefully before using this medication. Follow your doctor’s directions.

  • Singulair is usually taken once a day in the evening when used to prevent asthma or allergy symptoms. When treating exercise-induced bronchoconstriction, Singulair should be taken at least two hours before exercise and not taken again for 24 hours.
  • Swallow montelukast whole with a glass of water.
  • It may take several weeks before your symptoms improve. Continue taking this medication regularly.

Make sure to tell your doctor and pharmacist:

  • If you have any drug or other allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of asthma or liver disease.
  • If you are pregnant, planning on pregnancy or breast feeding.

Real Customers, Trustworthy Reviews

Read what others have to say before you buy — honest reviews from real people.

We have had very good service from the Canada Pharmacy Depot, obtaining a very expensive medication (in the USA) for the very same medication from India for a fraction of the US cost ($488/3mo supply vs $1400/1mo supply). This has been a godsend bc my husband has Parkinson's Disease and takes many medications to manage his condition. It does take longer to get the medication, but you just have to plan ahead for significant savings.
