Iglu Rapid Relief Mouth Ulcer Treatment - 8g

What Is the Best Mouth Ulcer Treatment for Fast Relief?

Mouth ulcers are small, painful sores that develop on the inside of the cheeks, lips, or tongue. They are incredibly common — the NHS estimates that around one in five people get them regularly. Most are harmless and clear up on their own, but the discomfort they cause while eating, drinking, or even talking can be genuinely miserable. That is where a targeted mouth ulcer treatment like Iglu Rapid Relief comes in. Available from our oral health range, this 8g gel is designed to get to work quickly and help you get on with your day.

Iglu Rapid Relief is an over-the-counter topical gel containing carbenoxolone sodium 1% w/w. It forms a thin, flexible film directly over the ulcer, acting as a physical barrier against the friction and irritation that makes ulcers so painful. It is a well-established product with a straightforward mechanism — no complicated regimen, no prescription needed.

How Does Iglu Rapid Relief Gel Work on Mouth Ulcers?

The active ingredient, carbenoxolone sodium, is a synthetic derivative of glycyrrhizinic acid (found in liquorice root). When applied to the ulcer, it works through a combination of actions:

• Forms a protective adhesive film over the ulcer surface to shield it from saliva, food, and mechanical irritation
• Reduces local inflammation at the site of the ulcer
• Creates a moist healing environment that supports tissue repair
• Provides a physical barrier that reduces pain on contact with food or drink

The gel sets quickly once applied, which means it stays in place even in the wet environment of the mouth. This is one of the key practical advantages over some liquid-based alternatives.

Who Should Use Iglu Rapid Relief Mouth Ulcer Gel?

Iglu Rapid Relief is suitable for adults and young people aged 12 and over who are experiencing the discomfort of minor mouth ulcers. It is particularly useful if your ulcers are triggered by stress, minor injury (such as biting your cheek), or certain foods. It is not intended for serious or persistent oral conditions.

• Adults aged 18 and over with occasional or recurrent minor mouth ulcers
• Teenagers aged 12–17 (under adult supervision)
• People who find eating or drinking painful due to ulceration
• Those looking for a simple, non-prescription mouth ulcer treatment

How Does Iglu Rapid Relief Compare to Other Mouth Ulcer Gels?

Is Iglu Rapid Relief Safe to Store and Use Long-Term?

Iglu Rapid Relief should be stored below 25°C, away from direct heat and sunlight. Do not refrigerate. Keep the cap tightly closed when not in use and always check the expiry date printed on the tube before applying. The 8g tube is compact enough to keep in a bag or desk drawer for when you need it.

If you find yourself reaching for a mouth ulcer treatment very frequently — say, more than once a month — it is worth speaking to your GP or dentist. Recurrent ulcers can sometimes be linked to nutritional deficiencies (such as iron, B12, or folate), hormonal changes, or underlying conditions that deserve proper investigation. You might also find it helpful to explore our vitamins and supplements range if deficiency is a contributing factor.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Iglu Rapid Relief and What Is It Used For?

Iglu Rapid Relief Mouth Ulcer Treatment is a topical gel used to relieve the pain and discomfort of minor mouth ulcers (also called aphthous ulcers). It contains carbenoxolone sodium 1% w/w, which forms a protective coating over the ulcer to reduce irritation and support healing. It is available without a prescription and is classified as a General Sale List (GSL) medicine in the UK. This makes it one of the more accessible options for anyone seeking a reliable mouth ulcer treatment without a GP visit.

Mouth ulcers are not contagious and are usually not serious, but they can make everyday activities like eating and speaking uncomfortable. The NHS notes that most ulcers heal within one to two weeks on their own, but using a protective gel can help manage symptoms in the meantime.

What Do You Need to Know Before Using Iglu Rapid Relief?

Before using this gel, read the following carefully. Do not use Iglu Rapid Relief if any of the contraindications below apply to you.

Do not use if you:

• Are under 12 years of age
• Are allergic to carbenoxolone sodium or any other ingredient in the gel
• Have ulcers that are unusually large, spreading, or have not healed after 3 weeks
• Have a known hypersensitivity to liquorice-derived compounds

Speak to your pharmacist or GP before use if you:

• Are pregnant or breastfeeding
• Have high blood pressure or heart disease
• Have kidney or liver problems
• Are taking spironolactone or amiloride (carbenoxolone may reduce their effectiveness at systemic doses, though topical use carries minimal risk)

Known drug interactions:

• No clinically significant interactions are expected at topical doses
• Systemic carbenoxolone (not this product) is known to interact with antihypertensives and diuretics — topical use is considered low risk, but always inform your pharmacist of all medicines you take

How Should You Use Iglu Rapid Relief Gel Correctly?

Using the gel correctly gives you the best chance of fast, effective relief. Follow these steps each time you apply it:

1. Wash your hands thoroughly before touching the affected area
2. Gently pat the ulcer dry using a clean tissue or cotton bud
3. Squeeze a small pea-sized amount of gel onto a clean fingertip or cotton bud
4. Apply the gel directly to the ulcer and press gently for a few seconds to help it adhere
5. Allow the gel to set for at least 30 seconds before eating, drinking, or rinsing
6. Repeat up to four times daily, or as directed by your pharmacist

If you are also managing other oral health concerns alongside your ulcer, our dental products range includes a variety of complementary options to support your overall mouth health.

What Are the Possible Side Effects of Iglu Rapid Relief?

Like all medicines, Iglu Rapid Relief can cause side effects, although not everyone experiences them. Because it is applied topically in small amounts, systemic side effects are very unlikely.

Common side effects:

• Mild stinging or burning sensation immediately after application
• Temporary local irritation at the site of the ulcer

Less common side effects:

• Localised redness or swelling around the application site
• Hypersensitivity reaction (rash, itching) — stop use immediately if this occurs

If you experience any unexpected or severe reaction, stop using the gel and contact your pharmacist or GP. You can also report side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

How Should You Store Iglu Rapid Relief Gel?

• Store below 25°C in a cool, dry place
• Do not refrigerate or freeze
• Keep the tube tightly closed when not in use
• Keep out of the sight and reach 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 pharmacy

If you are prone to recurrent mouth ulcers, it may be worth exploring whether nutritional gaps are playing a role. The NHS highlights that deficiencies in iron, vitamin B12, and folate are associated with recurrent aphthous ulcers. You can browse our vitamins and supplements collection for relevant options to discuss with your pharmacist.
