When will novo-pheniram be available again in Canada? What is the alternative?

You can buy it from Novapharm Limited Toronto Ontario M1B 2K9
A better batch for post nasal drip is AllerClear you can buy 10 mg 1 tablet every 24 hours at Costco.
It's the allergies that cause the post nasal drip the drains down the back of your neck -throat and gives you that the hoarse, cough - Strider effect which leads to hacking coughing up serious phlegm.

To whom it may concern,
The company that makes the novo-pheniram antihistamine is Teva Canada Ltd. Three offices-Toronto, Missasauga and Montreal.
Toll free number is 1-800-268-4129. I called them this morning (Oct. 4/10) and they called their warehouse and a supply should be sent out by Oct. 15th! I live in BC and our local Shopper's Drug Mart has been without the product for 7 months! Hopefully this will soon be rectified. Please call these folks to confirm or deny what they told me.
Regards from a fellow sufferer of allergies,
Fred

Novo-Pheniramin contains chlorpheniramine and is an antihistamine used to treat the symptoms of allergy and hayfever.
I am not sure when, and if, it will be available in Canada.
It is an older type of antihistamine and its use over the years has declined as newer more effective and better tolerated antihistamines have come onto the market.
Talk to your pharmacist - there are many other antihistamine tablets that should be just as effective that you can take instead.
