What is the difference between the various creams that are used for sore nipples such as Lansinoh and Xylocaine 5% Ointment?

Lanolin-based products, such as Lansinoh, can help to soothe, heal and protect sore, cracked nipples.

Xylocaine 5% Ointment, on the other hand, has a completely different formula that contains a local anaesthetic – lidocaine (lignocaine). The anaesthetic’s numbing effect provides fast* and effective relief from the pain and discomfort caused by sore, tender nipples.

What is the difference between various haemorrhoid ointments such as Anusol, Proctosedyl and Xylocaine 5% Ointment?

Haemorrhoid ointments can contain different types of active ingredients and are often recommended to be used in different ways.

For example, Proctosedyl ointment contains a local anaesthetic (cinchocaine) together with a steroid (hydrocortisone) to help reduce inflammation and swelling, numb pain and relieve itching. Proctosedyl should only be used for short-term symptom relief (not more than 7 days unless advised by your doctor) and is not recommended for children under the age of 12 years.1

Anusol ointment does not contain a local anaesthetic or steroid; the active ingredients are zinc oxide, Peru balsam and benzyl benzoate to relieve itching, burning and soreness.2

Xylocaine 5% Ointment contains the active ingredient lidocaine (lignocaine) which is a local anaesthetic that provides fast* and effective relief from haemorrhoid pain and discomfort.3

Xylocaine should not be used for prolonged periods unless advised by your doctor and should not be used in children under 2 years of age. If the condition persists or worsens, discontinue use and seek medical advice.
