To order a treatment, fill in a brief medical questionnaire. A doctor will review your order and prescribe treatment if it’s right for you. For test kits, you can just place an order. Once you’ve sent your sample to our UK-accredited partner laboratory, results and advice from our doctors will be ready in 2 to 3 days. How to Order

Cold sores are a types of herpes infection that affects your mouth causing sores and other symptoms. You can test yourself for cold sores using a home swab test kit.

Herpes infections can’t be cured so if you have cold sores you may need regular treatment for outbreaks. This is known as ‘acute treatment’. You may also need ongoing treatment to avoid regular outbreaks. This is called ‘suppressive treatment’.

Using a home test works in the following steps:

  1. Place an order and get your kit delivered to your door, or collect from a local post office (delivery is free)
  2. Collect your sample as per the instructions
  3. Send your samples to our UK-based, accredited partner laboratory (postage is free)
  4. Once your results are available (in 2 to 3 days), our doctors will review your results
  5. One of our doctors will contact you, via a secure and confidential message in your patient account, to let you know your results and give you advice and support on what to do next

In some cases, the doctor may need to ask for more information. They may contact you by phone, so make sure your telephone number is up to date in your online account.

Please note: where a generic product has been ordered we may use a range of manufacturers to provide you with your medication, in order to maintain our service levels.
