Aknemycin plus

How does it work?

Aknemycin plus solution contains two active ingredients; tretinoin, which is a form of vitamin A and erythromycin, which is an antibiotic. The combination is used to treat acne.

It is not known exactly how tretinoin works, but it is thought to loosen the cells in the surface of the skin. This helps to unblock pores, so that the skins natural oil producing glands can function normally.

In addition, tretinoin increases the turnover of the skin cells, which aids the natural exfoliation of the outer layers of skin. This also helps to unblock pores and decrease the formation of blackheads (comedones) and spots.

Erythromycin works by attacking the bacteria associated with acne, Propionibacterium acnes. This is a common type of bacteria that feeds on sebum (oil) produced by the sebaceous glands in the skin. It produces waste products and fatty acids that irritate the sebaceous glands, making them inflamed and causing spots.

Erythromycin prevents these bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. Erythromycin doesn’t directly kill the bacteria, but leaves them unable to increase in numbers. The remaining bacteria eventually die or are destroyed by the immune system.

By controlling bacterial numbers, erythromycin brings the inflammation of the sebaceous glands under control, and allows the skin to heal.

It may seem like your acne has got worse in the early weeks of treatment. This is due to the action of the medicine on deep, previously unseen blackheads and papules. It may take six to eight weeks before definite beneficial effects on the skin can be seen.

What is it used for?

Acne vulgaris

Warning!

This preparation is for external use only.

Clean and dry the affected area of skin thoroughly before applying this medicine. Use mild soap and pat rather than rub the skin dry. Using cotton wool, gauze, or clean fingertips, only apply enough medicine to cover the affected areas of skin lightly.

When you first start using this medicine it may cause temporary stinging or a feeling of warmth in the skin. When used correctly, it will usually make your skin slightly red, like mild sunburn. You shouldn't use the medicine any more frequently than directed by your doctor, as this won't make it any more effective or work any quicker. It may also make your skin very red or irritated or start peeling.

If you get any severe redness, swelling, itching, burning sensations, blistering, crusting or peeling of your skin after using the medicine, you should apply the medicine less frequently or stop using it temporarily. If the irritation persists you should stop using the medicine completely and consult your doctor.

Avoid contact of this medicine with the eyes, eyelids, nostrils, mouth, mucous membranes (eg linings of the nose) and broken areas of skin. If you accidentally get the medicine on these areas, carefully wash it off with water.

You can use cosmetics or moisturisers while using this medicine, but you should not apply them at the same time. Wash your skin thoroughly before applying the medicine. You can use cosmetics and moisturisers after the medicine has been absorbed into your skin.

Avoid exposure to sunlight, sunlamps or sunbeds while using this medicine, as it increases the sensitivity of your skin to UV light. If exposure to sunlight cannot be avoided, use protective measures such as sunscreens or protective clothing over the areas of skin you have treated with this medicine.

If your skin is sunburnt you should not use this medicine until your skin is fully recovered, as it may potentially cause severe irritation to the skin.
