Painless process. (No pun intended). Impossible to get doctors appointment during pandemic. If it is a simple renewal/prescription, use online practitioners and leave the actual visits for the ailing and infirm.

Charles

Very quick and easy to do. Can ask the doctor any questions about the medication. Only drawback is the initial fee, which is a bit pricey.

Maren

I really like how easy it is. I think you guys are doing something great. It's just a little pricey for me. But only because I used to be a student and had great prescription insurance!

Dallas

I am very impressed with this service - I have not received my medication just yet but so far the service I have received has been efficient and very friendly.

How effective is cold sore medication?

Treating a cold sore in its earliest stage can result in a smaller sore that heals quickly. Ideally, the cold sore may be stopped in its tracks, so it never appears at all. People who frequently get cold sores may want to have the appropriate medications on hand so that they can begin using them at the earliest possible stage.

What types of cold sore treatment do you offer?

The medicines that have been proven to work on cold sores are called antivirals, and they work to stop a virus from replicating. This, in turn, can stop the cold sore from developing or may reduce its size and healing time. Antiviral medications are only available with a prescription. Cold sore antivirals come in two different forms:

  • topical medication (cream) that is applied directly to the area
  • oral medications (pills) that are taken by mouth
What about side effects?

Antivirals are well-tolerated by most people. However, not everyone can or should take antivirals. The benefits and risks must be discussed with a doctor. 

Topical treatments can have some side effects including dry lips, dryness of skin, cracked lips, burning skin, shedding skin, itching, flakiness, and stinging on the skin.

The more common side effects of oral antiviral treatment include:

  • headache
  • dizziness
  • nausea
  • vomiting
  • stomach discomfort


If you experience side effects, we always suggest you discuss them with a doctor or pharmacist. Oral medications may not be the best choice for certain people. People with kidney damage or kidney failure may need a lower dosage. Be sure to tell your doctor if you have kidney problems before you start taking the drug.

Can I get a refill of my existing cold sore prescription?

Yes! But you will need to transfer your current prescription to Felix. Just choose the Transfer Now option to complete the steps to create a Felix account, complete your medical profile and give us all the information related to your current prescription. Our pharmacy will then contact your current pharmacy to complete the transfer.

How much does prescription cold sore medication cost?

Cold sore medication filled via Felix has a starting cost of $5.95 per outbreak (8 pills). The price does not include the pharmacy fill fee and it will vary based on the drug chosen, the province it is shipped to, and the refill schedule chosen.

Am I covered by my insurance?

Oral medications are generally covered by provincial plans and by some private plans. Make sure to upload your insurance card during your online visit so that the pharmacy can apply your coverage.


Can I get cold sore treatment online?

Yes, with Felix you can get treatment for cold sores online. Complete a short online assessment, select from the treatment options available, such as Valacyclovir (generic Valtrex). Once approved by a doctor, your medication will ship to your door.

You're in good hands.
