Mouth Ulcer & Cold Sore

Painful mouth ulcers and cold sores tend to appear at the worst times, and this range brings together the products that soothe and protect them. You will find mouth ulcer gels, sprays and rinses that form a protective layer, alongside cold sore creams and patches for the lips, suitable for adults and older children.

Choosing depends on where the problem is. For mouth ulcers, protective gels and sprays cover the sore area to ease discomfort while it settles, and antiseptic rinses help keep the mouth clean. For cold sores, antiviral creams are most useful at the first tingle, before the blister appears, while patches discreetly cover the area. Most flare-ups settle on their own within a week or two.

Every mouth ulcer and cold sore product here is stocked at Leahy's Pharmacy in Tralee, where our pharmacy team can help you choose. If an ulcer lasts longer than three weeks, keeps coming back or is very painful, it is worth getting it checked. For toothpaste, mouthwash and wider oral care, you can also browse our Dental Care range. Browse the full range below.

Frequently Asked Questions

What is the difference between a mouth ulcer gel and a spray? +
Gels are applied directly to the ulcer and form a protective layer that eases pain, which suits a single sore you can reach easily. Sprays cover a wider area and are handy for ulcers further back in the mouth or for several at once. Both aim to protect the area while it settles.
When is the best time to use a cold sore cream? +
Antiviral cold sore creams are most useful at the very first signs, the tingling or itching stage before a blister forms. Starting early gives the best chance of easing the episode. Patches can be applied once a blister appears to cover and protect it discreetly while it settles.
When should I get a mouth ulcer checked? +
Most mouth ulcers clear within a week or two. See your dentist or GP if an ulcer lasts longer than three weeks, is unusually large or painful, or keeps recurring in the same spot. Our pharmacist can suggest products to ease discomfort while a normal ulcer settles.
