Cold Sore Starting? Get Antiviral Treatment Fast in Ontario

With cold sores, timing matters - antivirals help most when started at the first tingle. Here is how to get assessed quickly in Ontario.

If you get cold sores, you know the warning signs: the tingle, itch, or tightness a day before the blister appears. That early window matters, because antiviral treatment tends to work best when it is started as soon as symptoms begin. In Ontario, a pharmacist can help you act quickly.

Why early treatment helps

Cold sores are caused by the herpes simplex virus. Antiviral medication does not cure the virus, but starting it early can shorten an outbreak and ease symptoms. Waiting until the blister is fully formed gives you less benefit - so speed counts.

Get assessed at the first sign

Start the cold sore assessment as soon as you feel one coming on. A licensed Ontario pharmacist reviews your answers and follows up - within 24 business hours (our average is about 2 hours) - and prescribes an antiviral when it is appropriate. Because you are not waiting for an appointment, you can catch it in that early window.

Cost

Free with a valid Ontario health card, or a flat $30 without. Treatment is provided only when the pharmacist judges it appropriate.

When to see a doctor

Get in-person care if sores are severe or widespread, last more than two weeks, are near your eyes, keep recurring frequently, or if you have a weakened immune system. Sores near the eye in particular need prompt medical attention.
