What is Aciclovir 5% cream?

Aciclovir 5% is an antiviral cream that is used for the treatment of recurrent cold sores. It is an unbranded version of a treatment called Zovirax, which is widely available and very well known.

Aciclovir 5% cream can effectively treat cold sores, reducing their length and severity when applied in the early stages of an outbreak.

You can buy this cream from Medicine Direct following an online consultation with one of our registered doctors, who will assess your symptoms and prescribe this medication if they decide it is suitable for you to use. You can then order Aciclovir 5% cream from our online pharmacy. Place your order by 2pm and we can offer you next day delivery, absolutely free.

What is Aciclovir 5% cream used to treat?

Aciclovir cream is used in the treatment of cold sores that keep coming back. This cream contains the active ingredient aciclovir which can, in most cases, help to heal cold sores within five days of treatment.

Recurring cold sores usually appear in the same place they did last time. Before a cold sore turns to a blister around the lip, the skin in the affected area often feels to be burning or stinging, which is a sign you are going to develop a cold sore. Aciclovir cream should be applied to your lip as soon as you start to feel this sensation.

It works by killing the herpes simplex virus (HSV) that causes cold sores to appear. If your cold sore is caught at an early stage, using Aciclovir cream may prevent it from developing into a blister on the lip or face.

When to see a doctor

If you have not seen an improvement after nine days of using this treatment, you should make an appointment to see a doctor. They may recommend trying a different form of treatment.

The earlier you start to use Aciclovir cream, the more effective it will be. You should not use it if it is more than 5 days after you develop a cold sore; always try to begin applying Aciclovir cream as soon as you feel a cold sore beginning.

Who can use Aciclovir cream?

Aciclovir cream is an effective treatment for cold sores, but it is not suitable for everyone to use.

You should not use this cream without speaking to your doctor if:

  • You are allergic to aciclovir or any of the other ingredients contained in this medicine (please refer to the Ingredients tab for a full list)
  • You have ever had an allergic reaction to another medicine or skin product

You have any conditions where your immune system is impaired or your body is not able to fight infections properly, such as HIV or you have had a bone marrow transplant.

How to use Aciclovir cream

Wash your hands with soap and water before applying the cream.

Squeeze a small amount of the cream onto a clean finger.

Apply the cream to the cold sore, gently rubbing it into the skin until the cream has been absorbed.

Apply Aciclovir 5% cream to the cold sore(s) five times each day. Ideally, do this every four hours.

Re-wash your hands after you have applied the cream, this will stop the cold sores from spreading and reduce the chance of them becoming infected.

Warnings and drug interactions

Before taking a new form of medicine, you should always make sure you tell your doctor or pharmacist if you are currently using any other medication. This includes any prescription or non-prescription medication, herbal remedies, vitamins or supplements you are currently taking or have recently taken. Certain medicines can interact with others, increasing your risk of side effects and potentially stopping one or both medicines from working effectively.

Before you start to use Aciclovir cream

Do not apply this cream to the inside of your mouth or the vagina.

If you have cold sores which are spreading to other areas and are very sticky or have a thick crust, these may be signs of a bacterial infection. If you experience this, you should see your doctor; you may require treatment with antibiotics.

Seek medical attention if you keep developing cold sores frequently as this may be a sign of reduced immunity.

Speak to your doctor if your cold sore has not healed after 10 days of treatment with Aciclovir.

If you have any questions or concerns at all, we strongly advise you to discuss these with your doctor before you start to use this medicine.

Pregnancy and breastfeeding
