Real Customers, Honest Reviews

Singulair is an oral medication used to prevent asthma attacks and treat allergy symptoms. It works by preventing the body from releasing chemicals that cause swelling in the lungs and airways. Singulair may also be used to prevent exercise-induced asthma in people who are not already taking the drug for asthma or allergies.


Always follow your doctor’s instructions and use Singulair exactly as prescribed.

  • For asthma and allergy prevention, Singulair is usually taken once daily.
  • If you use Singular to prevent exercise-induced symptoms, take at least 2 hours before exercise.
  • Do not take more than one dose in 24 hours.

If your asthma symptoms tend to get worse when taking aspirin, avoid aspirin and other NSAIDs while taking Singulair.

Before taking Singulair, inform your doctor if you have any of the following:

  • Asthma
  • Allergic reactions to aspirin
  • Phenylketonuria
Side Effects

Common side effects of Singulair include:

  • Flu symptoms (fever, body aches, chills)
  • Cold symptoms (sinus pain, cough, stuffy nose, sore throat)
  • Headache
  • Loss of bladder control in children
  • Stomach pain
  • Diarrhea

Contact your doctor if you experience these more serious side effects:

  • Skin rash, tingling, bruising, numbness, muscle weakness
  • Pain, swelling, or warmth in ears
  • Severe skin reaction – sore throat, swollen face or tongue, burning eyes, fever, skin pain, red or purple rash with blistering

If I already take Singulair for asthma control, can I take an extra dose before exercise?

No. If you already take Singular, another dose before exercise isn’t necessary. Don’t take more than one dose per day unless directed by your doctor.

Will Singulair help in the event of an asthma attack?

Singulair is not a rescue medication, and doesn’t replace rescue inhalers. Regular use of Singulair may help better control your asthma, so that attacks happen less often.

What's the difference between generic drugs and brand name drugs?

What's the difference between the branded products you sell and the ones I get locally?
The branded drugs we sell are chemically and therapeutically no different from the ones you get in your local pharmacy. They both generally come from the same exact manufacturer. Generally, the main difference* is in the packaging and the price. Our packaging may be different from what you get locally, but we're also much cheaper.

* Other differences may include differences in trade name, form, and general appearance.

Why are there packaging differences?
Due to differences in government regulation, different countries have different packaging requirements. For example, a product in Canada (or any other country) will have different packaging than the same product in the US even though both drugs are chemically and therapeutically equivalent and are generally manufactured by the same exact company.

Why are your drugs so much cheaper?
Due to government price controls, medications from Canada and many other countries are often significantly cheaper than in the United States. Also, other countries may have more affordable generic versions of drugs, which may not yet be available in the US.
