What Is Blistex Relief Cream and How Can It Help?

 

Blistex Relief Cream is a medicated topical cream designed to soothe and protect sore, dry, and cracked lips, including those affected by cold sores. It comes in a convenient 5g tube, making it easy to keep in your bag or pocket for whenever you need it. Cold sores and chapped lips can be genuinely uncomfortable — and sometimes they appear at the worst possible moment. That's where a reliable, over-the-counter option like this one can make a real difference. You can browse a wider range of similar products in our creams and ointments collection if you're looking for other topical treatments.

The cream is suitable for adults and children over 12 years of age and is available without a prescription. It works on the surface of the lip to provide fast-acting comfort, helping to ease the pain and irritation that often accompanies cold sores or severely dry lips.

 

How Does Blistex Relief Cream Work on Sore Lips?

 

The formula contains three key active ingredients, each playing a distinct role in relieving lip discomfort:

  • Camphor — acts as a mild topical analgesic and counterirritant, helping to reduce the sensation of pain and itching at the application site.
  • Phenol — provides a mild antiseptic and local anaesthetic effect, which can help soothe the stinging and soreness associated with cold sores and cracked lips.
  • Allantoin — a skin-conditioning agent that promotes cell regeneration and helps to moisturise and soften damaged lip tissue, supporting the natural healing process.

Together, these ingredients work on the surface of the skin to provide symptomatic relief. It's worth noting that Blistex Relief Cream does not contain an antiviral agent such as aciclovir, so it will not treat the herpes simplex virus that causes cold sores — it simply helps manage the discomfort while your body heals.

 

Who Is Blistex Relief Cream Suitable For?

 

This cream is a good option for a broad range of people dealing with common lip complaints. It's particularly useful if you experience recurrent cold sores or frequently suffer from dry, chapped lips due to cold weather, wind exposure, or dehydration.

  • Adults and children aged 12 years and over
  • People with dry, cracked, or chapped lips
  • Those experiencing the early discomfort of a cold sore
  • Anyone seeking a non-prescription, topical lip treatment

It is not suitable for children under 12 years of age. If you are pregnant, breastfeeding, or have a known allergy to any of the ingredients, speak to your pharmacist before use.

Specifications of Blistex Relief Cream 5g

 

What Is Blistex Relief Cream and What Is It Used For?

 

Blistex Relief Cream is a topical, over-the-counter medicated cream used to relieve the pain, soreness, and discomfort associated with cold sores and dry or cracked lips. It contains a combination of camphor, phenol, and allantoin — ingredients that work together to soothe irritated lip tissue and support the skin's natural recovery. Cold sores are caused by the herpes simplex virus type 1 (HSV-1), which affects a significant proportion of the UK population. While this cream does not treat the virus itself, it helps manage the uncomfortable symptoms that come with an outbreak, such as tingling, soreness, and dryness.

 

What Do You Need to Know Before Using Blistex Relief Cream?

 

Before applying this cream, there are some important points to be aware of. Do not use it if you are allergic to any of the listed ingredients. Always read the label carefully before first use.

Do not use Blistex Relief Cream if you:

  • Are allergic to camphor, phenol, allantoin, or any other ingredient in the formulation
  • Are under 12 years of age
  • Have open wounds or severely broken skin beyond normal cold sore presentation
  • Are pregnant or breastfeeding without first seeking pharmacist or GP advice

Drug interactions:

  • No significant drug interactions are currently known for topical use of this product
  • If you are using other topical lip treatments simultaneously, speak to your pharmacist to avoid potential skin reactions

 

How Should You Use Blistex Relief Cream Correctly?

 

Using this cream correctly will help you get the most benefit from it. Apply it only to the affected area of the lips — not inside the mouth, near the eyes, or on other areas of skin unless directed by a healthcare professional.

  1. Wash your hands thoroughly before and after application.
  2. Squeeze a small amount of cream onto a clean fingertip.
  3. Gently apply to the affected area of the lip.
  4. Smooth the cream over the sore or dry area without rubbing vigorously.
  5. Repeat up to four times daily as needed.
  6. Avoid eating or drinking immediately after application to allow the cream to absorb.
Indication Age Group Dose Frequency
Cold sore discomfort Adults and children 12+ Small amount to affected area Up to 4 times daily
Dry or cracked lips Adults and children 12+ Small amount to affected area Up to 4 times daily
Children under 12 Not recommended

If symptoms persist beyond 7 days or worsen, stop using the product and consult your pharmacist or GP. You might also find it helpful to explore our oral health collection for complementary products that support lip and mouth care.

 

What Are the Possible Side Effects of Blistex Relief Cream?

 

Like all medicines, Blistex Relief Cream can cause side effects, although not everyone will experience them. Most side effects are mild and localised to the area of application.

Common side effects:

  • Mild stinging or tingling sensation immediately after application
  • Temporary redness at the application site

Less common side effects:

  • Skin irritation or contact dermatitis
  • Dryness or peeling of the lip skin with prolonged use
  • Allergic reaction — including rash, itching, or swelling (seek medical advice promptly if this occurs)

If you experience any signs of a serious allergic reaction — such as swelling of the face, lips, or throat, or difficulty breathing — stop use immediately and seek emergency medical attention. The NHS provides guidance on recognising and responding to allergic reactions.

 

How Should You Store Blistex Relief Cream Safely?

 

Correct storage helps maintain the product's effectiveness and safety. Follow these guidelines:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Always replace the cap firmly after use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the tube
  • Do not dispose of medicines via wastewater or household waste — return unused product to your local pharmacy

If you're managing multiple skin conditions alongside lip care, our first aid collection includes a range of topical treatments that may be useful to have at home.

Frequently Asked Questions

Where can I buy Blistex Relief Cream online in the UK?

You can buy Blistex Relief Cream 5g directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £9.99 with fast delivery. It is a General Sale List (GSL) medicine, meaning no prescription is required. It is also widely available in UK pharmacies and supermarkets.

How does Blistex Relief Cream work on cold sores?

Blistex Relief Cream contains camphor and phenol, which act as mild topical analgesics to reduce pain and stinging, and allantoin, which helps to moisturise and support skin healing. It does not contain an antiviral ingredient, so it soothes symptoms rather than treating the herpes simplex virus itself. It is best applied at the first sign of discomfort for maximum benefit.

How do I apply Blistex Relief Cream step by step?

Wash your hands before and after use, then apply a small amount of cream to the affected lip area using a clean fingertip. Smooth it gently over the sore or dry area and allow it to absorb before eating or drinking. Repeat up to four times daily as needed.

How many times a day can I use Blistex Relief Cream?

You can apply Blistex Relief Cream up to four times daily. Space applications evenly throughout the day for consistent relief. Do not exceed the recommended frequency without speaking to a pharmacist.

What are the side effects of Blistex Relief Cream?

Most people tolerate Blistex Relief Cream well, but some may experience mild stinging, temporary redness, or skin irritation at the application site. Rarely, an allergic reaction may occur — if you notice swelling, a rash, or difficulty breathing, stop use immediately and seek medical help. Contact your pharmacist if you are unsure about any reaction you experience.

Can children use Blistex Relief Cream?

Blistex Relief Cream is suitable for adults and children aged 12 years and over. It should not be used in children under 12 years of age. If your child is under 12 and experiencing cold sore symptoms, speak to your GP or pharmacist for appropriate advice.

Is Blistex Relief Cream safe to use during pregnancy?

If you are pregnant or breastfeeding, you should speak to your pharmacist or GP before using Blistex Relief Cream. While topical application involves minimal systemic absorption, it is always best to seek professional guidance during pregnancy. Your pharmacist can advise on the safest options for you.

How long should I use Blistex Relief Cream for?

Blistex Relief Cream is intended for short-term use to relieve acute symptoms. If your symptoms have not improved within 7 days, or if they worsen at any point, stop using the cream and consult your pharmacist or GP. Prolonged use beyond the recommended period is not advised without professional guidance.

What are the alternatives to Blistex Relief Cream for cold sores?

If you need an antiviral treatment for cold sores, Zovirax Cold Sore Cream (aciclovir 5%) is a commonly used alternative that targets the herpes simplex virus directly. For dry or chapped lips without cold sores, simple emollient lip balms may be sufficient. You can explore a range of topical options in our creams and ointments collection.

Can I use Blistex Relief Cream and an antiviral cream at the same time?

Using two topical products on the same area simultaneously is generally not recommended without pharmacist advice, as it may affect absorption or cause skin irritation. Speak to your pharmacist before combining Blistex Relief Cream with any other topical treatment. They can advise on the safest and most effective approach for your situation.

Does Blistex Relief Cream prevent cold sores from spreading?

Blistex Relief Cream does not contain antiviral ingredients, so it will not prevent the spread of the herpes simplex virus. Cold sores are contagious, particularly when the blister is present, so avoid close contact such as kissing and do not share lip products. The NHS advises washing hands frequently during an outbreak to reduce the risk of spreading the virus.

What happens if I accidentally swallow Blistex Relief Cream?

If a small amount is accidentally ingested during normal lip application, it is unlikely to cause harm. However, if a larger amount is swallowed — particularly by a child — contact NHS 111 or your nearest A&E immediately. Always store the product out of the reach of children to prevent accidental ingestion.

Can I wear lipstick or lip balm over Blistex Relief Cream?

It is best to allow Blistex Relief Cream to absorb fully before applying any other lip product on top. Layering products immediately may dilute the cream's effectiveness or cause irritation. If you regularly use lip products, our skin care collection includes options that may complement your lip care routine.

Is there any research supporting the use of Blistex Relief Cream?

The individual active ingredients — camphor, phenol, and allantoin — have established histories of use in topical lip and skin care formulations. Allantoin in particular is well-documented in dermatological literature for its skin-conditioning and healing properties. The product is licensed for sale in the UK as a General Sale List medicine, indicating it has met regulatory standards for safety and efficacy.

How should I store Blistex Relief Cream at home?

Store Blistex Relief Cream below 25°C in a cool, dry place away from direct sunlight and heat. Always replace the cap firmly after use and keep the tube out of the reach of children. Check the expiry date on the tube before each use and do not use the product after that date.

How Should You Use Blistex Relief Cream?

Blistex Relief Cream is applied directly to the affected area of the lips. Always wash your hands before and after application to prevent spreading infection, particularly if you are treating a cold sore. Avoid getting the cream in your eyes or inside your mouth.

What Is the Correct Dose of Blistex Relief Cream?

The correct dose depends on the indication and the age of the person using it. Always use the smallest amount needed to cover the affected area — there is no benefit to applying more than necessary, and excessive use may cause irritation.

When Is the Best Time to Use Blistex Relief Cream?

For cold sore discomfort, applying the cream at the very first sign of symptoms — such as tingling or itching — may help to manage discomfort more effectively from the outset. For dry or chapped lips, applying the cream after meals and before going to bed can help to maintain moisture and support overnight recovery. Spacing your applications evenly throughout the day will provide more consistent relief than applying multiple doses close together.

How Long Can You Use Blistex Relief Cream For?

Blistex Relief Cream is designed for short-term symptomatic relief. Most cold sores resolve within 7 to 10 days, and dry lip symptoms should improve within a similar timeframe with appropriate care. If your symptoms have not improved after 7 days of use, or if they worsen at any point, stop using the cream and seek advice from your pharmacist or GP. Do not use this product continuously for extended periods without professional guidance, as prolonged use of phenol-containing products on the skin is not recommended.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Blistex Relief Cream?

Blistex Relief Cream is generally well tolerated when used as directed. However, as with any topical medicine, some people may experience mild side effects at the application site. These are usually short-lived and resolve on their own without any treatment.

  • Mild stinging or tingling sensation immediately after application
  • Temporary redness or warmth at the site of application
  • A cooling sensation due to the camphor content

What Are the Less Common Side Effects of Blistex Relief Cream?

Less commonly, some individuals may experience more persistent or noticeable reactions. If any of the following occur and do not resolve quickly, stop using the product and speak to your pharmacist.

  • Contact dermatitis — inflammation or irritation of the skin around the lips
  • Dryness or peeling of the lip skin, particularly with frequent use
  • Increased sensitivity or discomfort at the application site

What Are the Serious Side Effects of Blistex Relief Cream?

Serious side effects are rare but can occur, particularly in people with a known sensitivity to any of the active ingredients. An allergic reaction to camphor, phenol, or allantoin — though uncommon — is possible. Signs of a serious allergic reaction include swelling of the face, lips, tongue, or throat, difficulty breathing, a widespread skin rash, or dizziness. If you experience any of these symptoms, stop using the cream immediately and seek emergency medical attention by calling 999 or going to your nearest A&E department.

What Should You Do If You Experience Side Effects of Blistex Relief Cream?

For mild side effects such as temporary stinging or redness, no specific action is usually needed — these typically resolve within a few minutes of application. If irritation persists or worsens, wash the area gently with cool water and discontinue use. For any side effect that concerns you, contact your pharmacist or GP for advice. You should also report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Blistex Relief Cream Interact With Other Medicines?

No significant drug interactions have been identified for Blistex Relief Cream when used topically as directed. However, applying multiple topical products to the same area simultaneously — such as another lip cream or antiviral treatment — may affect how well each product is absorbed or could increase the risk of local irritation. Always inform your pharmacist of any other medicines or topical products you are using before starting a new treatment.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
