Covid-19 Service Update

At North Drugstore, the health and safety of our customers and staff is our highest priority. Due to the worldwide Covid-19 pandemic affecting us all, there have been some changes within our industry in general, and in our company specifically, that we want to make our customers aware of.

Call Center

Our current call center hours of operation are 6AM – 9PM every day, seven days per week. If you are experiencing increased hold times or are calling outside of these hours, please leave us a message or send us an email and we will get back to you as soon as we can. Due to increased demand on telephone networks worldwide, you may experience some intermittent connection problems. If this happens our agents will call you back.


We are currently seeing delays in our regular shipping times. Our normal shipping time averages 1 - 2 weeks. Shipments may now take an additional 2 – 4 weeks or more to arrive, depending on the source country of your order.

Please note that these times are averages and individual shipping times will vary. We highly recommend that you place your order at least 2 – 4 weeks or more ahead of your normal reorder time to avoid running out of your medication.

These are industry-wide delays and are mainly occurring due to disruptions in local postal delivery in the countries where our customers live. They are temporary, and we thank the shipping and delivery personnel who are working hard for all of us during this global crisis.

Please Note: As these types of shipping delays are not within our direct control, we are temporarily adjusting our regular Shipping Guarantee from 30 days to 60 days. We will provide updates as the situation changes.

Our Commitment

If you have any questions about any changes in our service please do not hesitate to contact us. Our staff are working tirelessly to ensure the timely fulfillment and delivery of all orders. The health of our customers and staff is our highest priority and we remain committed to providing service at the highest level.

We thank you for your support in these challenging times.

Full information about Singulair

Basic Information On Singulair

Singulair belongs to the family of drugs called leukotriene receptor antagonists. It inhibits leukotriene. Leukotriene is a chemical produced by the body when an allergen, like pollen, is breathed in. This chemical swells the lungs and tightens the muscles around the airways, thus causing asthma. This medication is effective in curbing and relieving respiratory allergies like seasonal allergic rhinitis (hay fever). The Singulair drug is also used to treat runny nose and sneezing in pediatric patients over 2 years of age, children and adults. In patients above 15 years of age who are not taking this medicine for some other condition, it may also be prescribed for preventing bronchoconstriction (narrowing of the air passages in the lungs) caused due to exercise.

Precautions / Side Effects Of Singulair

Singulair contains Montelukast which may cause some common side effects like nausea, stomach upset or pain, stuffy nose, headache, indigestion, dizziness and cough. However, you should contact your doctor if you experience any of the serious allergic reactions like: aggressive behavior, irregular heartbeat, swelling of the mouth, itching, and mental or mood changes. You should not take brand or generic Singulair if you are sensitive to aspirin and other non-steroidal anti inflammatory agents. 4 mg and 5 mg chewable tablets of this medicine contain phenylalanine, and should not be taken if you have phenylketonuria.

Montelukast is not a fast-action medicine for emergency conditions. You should continue using your inhaler and any other medicines as prescribed. However, the dose inhaled may be reduced slowly. If you are taking the brand or generic Singulair, you should intimate you doctor about other medicines that you are taking, existing medical conditions, and other persistent side effects. You should also report to the doctor immediately in case you notice any neuropsychiatric events.

Singulair Dosage

Singulair is administered once a day in the evening. The recommended dose for small children 2 to 5 years of age is one 4 mg tablet or one pack of 4 mg oral granules. For children in the age group 6-14 years, one 5 mg chewable tablet should be taken while for adolescents and adults, the prescribed dose is one 10mg tablet daily. To prevent EIB, one 10 mg tablet should be administered 2 hours before exercise. Another dose of this medication should be administered within 24 hours of the previous dose. However, patients taking another dose of Singulair to treat chronic asthma should not take another dose to prevent EIB.
