To request a treatment, fill in a brief medical questionnaire. A doctor will then prescribe treatment if it’s right for you. For test kits, you can just place an 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:
- Request and get your kit delivered to your door, or collect from a local Post Office (delivery is free)
- Collect your sample as per the instructions
- Send your samples to our UK based, accredited partner laboratory (postage is free)
- Once your results are available (in 2 to 3 days), our doctors will review your results
- 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, when you request a generic (non branded) treatment, the product you receive may look slightly different than what we show on our website. The active ingredient in the medication will be exactly the same though. This is because we use a range of manufacturers to ensure we always have enough stock for patients. If you have any questions, you can message our Customer Support team or doctors through your account.

Common side effects of cold sore treatment
Aciclovir can cause the following side effects:
- headaches and feeling sick
- tummy pain
Cold sores are small blisters that appear on or around the edge of the lips. They can split and bleed slightly which can be painful. Cold sores are common and affect men and women of all ages.
A cold sore develops when you are infected with either Herpes Simplex Virus-1 (HSV-1) or Herpes Simplex Virus-2 (HSV-2) around the mouth. This is usually contracted via direct contact with another person who has a cold sore, such as kissing, or by sharing toiletries such as lip balm. It can also be caught via oral sex with someone who has genital herpes.
Being infected with HSV-1 or HSV-2 will not always cause symptoms. Usually people who have an infection will have outbreaks from time to time but can go for long periods without any symptoms. It isn’t fully understood why an outbreak happens, but some things seem to trigger them – for example if you are unwell anyway (coughs colds, flu), if you are stressed or run down, if you are on your period, or if you spend time in bright direct sunlight.
Cold sores can affect anyone who has come into contact with the virus. Once you have been infected, a cold sore can flare up at any time but can be managed with appropriate treatment.
You have a higher risk of catching the virus if you:
- kiss someone with unhealed cold sore blisters
- share cosmetic products with someone who has cold sores
- have oral sex with someone who has genital herpes
To reduce your risk of cold sores you should avoid direct contact with someone else’s cold sores. Cold sores are often triggered when you are run down or stressed so if you have the infection, you should avoid these triggers to prevent an outbreak of symptoms.
The main symptoms of cold sores are visible blisters around your mouth. Development of a cold sore blister starts with a strange tingling sensation on or around the lips. Small blisters then form and can crack and bleed which can be painful.
Cold sores are not generally dangerous but can sometimes be distressing or uncomfortable.
A cold sore test kit is a way of checking if you have cold sores without having to take a test in person.
The test is posted to your door or a post office for you to collect. It contains a swab which you use to collect a sample from the area that you think might be a cold sore. You then post this to our lab for checking.
The results of your test will be displayed in your account. You can then see whether or not you need to get treatment or if your symptoms are being caused by another condition.
Cold sores can be treated with antiviral medication, which helps your symptoms go away faster (acute treatment) or helps to stop symptoms from coming on, if you are getting a lot of outbreaks (suppressive treatment)
We offer the following cold sore treatments:
- Aciclovir for acute treatment
- Aciclovir for suppressive treatment
A course of suppressive therapy can reduce the number of cold sore outbreaks you have over a period of time, this is usually taken for 6 to 12 months. It is usually helpful if you have more than 6 outbreaks in a year. The short course treatment therapy helps to ease a current outbreak more quickly.
