FAQ

No. In the United Kingdom, aciclovir 5% cream is a Pharmacy (P) medicine and does not require a prescription. It is supplied under a pharmacist's supervision.

A generic aciclovir 5% cream contains the same active ingredient, aciclovir, at the same stated strength. The cream base, inactive ingredients, packaging and appearance can differ between products, so check the label if you need to avoid a particular ingredient.

Do not increase the amount applied or extend treatment on your own. Seek medical advice if the sore is not healing after the recommended treatment period, becomes severe or widespread, affects the eye, or occurs with a weakened immune system.

Store the cream at 25°C; short excursions between 15°C and 30°C are permitted. Keep the tube tightly closed and do not freeze it. Keep it out of the sight and reach of children.

Zovirax cream contains aciclovir, an antiviral medicine used on the skin for herpes simplex infections, including cold sores on or around the lips. It helps limit viral replication but does not remove herpes simplex virus from the body or prevent all future outbreaks.

Apply a thin layer to the affected skin and surrounding area, usually five times daily at roughly 4-hour intervals while awake. Start at the first tingling or blistering signs where possible, wash hands before and after application, and avoid contact with the eyes and inside of the mouth.

Zovirax (Aciclovir) Cream: Key Facts

  • Used for recurrent herpes labialis (cold sores) on the lips or face caused by the herpes simplex virus (HSV).
  • For adults and adolescents aged 12 and over with a normal immune system.
  • Apply only to the outside of the lips and face. Do not use it in the eyes or inside the mouth or nose.

What It Treats

Zovirax cream contains aciclovir and is used to treat recurrent herpes labialis (cold sores) when applied early in an outbreak.

Zovirax for Cold Sores vs Genital Herpes

Condition Can Zovirax (aciclovir) cream be used? Notes
Cold sores on the lips or face (recurrent herpes labialis) Yes (on-label) Start early, at the tingling or itching stage, or when lesions appear.
Genital herpes No Zovirax cream is not intended for use on the genitals. In the UK, genital herpes is usually treated with prescription oral antivirals, based on a clinician's advice.

What Zovirax Cream Does Not Do

  • It does not cure herpes (HSV stays in the body).
  • It does not prevent future outbreaks.
  • It does not stop the virus being passed on to other people.

Before You Use

  • Do not use if you are allergic to aciclovir, valaciclovir or any of the ingredients in the cream.
  • Children under 12 years: safety and effectiveness have not been established. Only use it if your healthcare provider in the United Kingdom tells you to.

If you are pregnant, planning to become pregnant or breastfeeding, speak to your healthcare provider before using this medicine.

This product contains propylene glycol and cetostearyl alcohol, which may cause local skin reactions such as stinging or burning. If you know you are sensitive to these substances, ask a healthcare professional before using it.

How to Use

Question Answer
How much should I apply? Apply a thin layer, using enough to fully cover the affected area.
When should I start? As early as possible, at the first sign of an outbreak (tingling or itching) or when lesions appear.
How often? 5 times a day.
How long? 4 days. If it has not healed, you may continue for up to 10 days. See a healthcare provider if symptoms continue beyond that.
How quickly does it work? It may shorten the episode if started early, but it is not a cure and results vary from person to person.

If you miss a dose, apply it as soon as you remember. If it is nearly time for the next application, skip the missed dose and continue with your usual schedule.

If you apply too much, an overdose on the skin is unlikely. If irritation occurs, wash the area gently and speak to a healthcare provider.

  • Store at or below 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F).

Health and Hygiene

Cold sores are small, fluid-filled blisters that usually appear on or around the lips and are caused by HSV. To help reduce the risk of spreading the virus during an outbreak:

  • Avoid close contact with other people.
  • Do not share items that may have come into contact with the sore, such as utensils, towels or lip balm.
  • Wash your hands often, especially after touching the affected area.
  • Avoid picking at blisters to help prevent a secondary infection.

Customer questions

Asked by Hannah, Leicester, United Kingdom

My Zovirax cream order to Leicester has been marked as dispatched. Does that mean it will arrive tomorrow?

Answered by Support team

Not necessarily. Dispatch means the order has left for delivery; arrival depends on the delivery service selected and the carrier's progress.

Asked by Aoife, Lisburn, United Kingdom

I live in Lisburn, Northern Ireland. Can I confirm whether Zovirax cream can be delivered to my address before I pay?

Answered by Support team

Yes. Enter your delivery address at checkout to see the delivery options available for your Lisburn postcode before completing payment.

Asked by Declan, Belfast, United Kingdom

Before I order from Belfast, can I use my postcode to check if this cream can be delivered to me?

Answered by Support team

Yes. Add the product to your basket and enter your Belfast postcode at checkout; the available delivery options will be shown there.

Asked by Matthew, Portsmouth, United Kingdom

My new tube looks different from the one I ordered before. What should I compare before using it?

Answered by Support team

A different appearance alone does not mean the cream is wrong. Compare the active ingredient, 5% strength, cream dosage form, manufacturer and package label, plus the batch number, expiry date and tube condition; do not use it if any of these are incorrect or the seal is damaged.

Asked by Sophie, Reading, United Kingdom

I have just found out that I am pregnant and had started using the cream for a cold sore. Should I carry on?

Answered by Support team
Medical reviewed by Donna Brettler

Absorption of aciclovir through the skin is minimal, but use in pregnancy should be considered against the expected benefit. Speak with your midwife, GP or pharmacist before deciding whether to continue, especially if you need treatment over a large area or for longer than usual.
