Type of medicine	Anti-inflammatory painkiller
Used for	Painful mouth and throat conditions such as mouth ulcers, sore throat, gingivitis, stomatitis, and post-dental surgery discomfort
Also called	Difflam®
Available as	Mouth rinse (mouthwash), lozenges, or spray

Benzydamine works by inhibiting prostaglandin formation, which are substances responsible for pain, inflammation, redness, swelling, and heat in injured or infected areas of the mouth and throat. Its unique indazole derivative structure provides combined anti-inflammatory, local anesthetic, and analgesic effects, superior for acute oral inflammation compared to traditional NSAIDs. Clinical studies confirm its efficacy in treating oral mucositis, ulcers, and preventing post-operative sore throat after intubation.

Before using benzydamine

Allergy warning

Do not use benzydamine if you are allergic to it or any similar medicines. Signs of allergy include rash, itching, swelling, or breathing difficulties. Inform your doctor if you have allergies to NSAIDs or other painkillers.

Pregnancy and breastfeeding

Benzydamine is generally considered safe during pregnancy and breastfeeding due to its topical action and low systemic absorption. However, consult your doctor before use, especially in the first trimester or if breastfeeding. No major risks have been reported in clinical data.

Babies and children

For children, dosing is weight-based: use 1 spray per 4kg of body weight, up to a maximum of 8 sprays (ages 5-12 years) or 14 sprays (over 12 years), 1.5-3 hours apart. Lozenges and mouthwash are suitable for children over 6-12 years. It is effective for teething pain or general sore throats in kids. Always supervise children to prevent swallowing.

Using other medicines

Benzydamine has few interactions due to topical use. It may be safely combined with paracetamol or ibuprofen for additional relief if needed. Avoid concurrent use with other local anesthetics without advice.

Conditions to watch

Use cautiously if you have asthma, as NSAIDs can trigger attacks. Discontinue if symptoms worsen or persist beyond 7 days.

How and when to use benzydamine

Benzydamine eases painful conditions of the mouth or throat by direct application. Always follow package instructions or professional advice.
