Use Derlin for as long as your doctor tells you. You may have to use it for several months to clear your acne completely. Even the initial benefits may take several weeks to appear following which you shall be able to note a gradual but definite improvement. Usually, Derlin should be used for a maximum of 12 weeks. You may need to use more than one tube of Derlin during each course of treatment.

Derlin treats and prevents acne by stopping the growth of bacteria (Propionibacterium acnes) which causes it. Acne is an extremely common skin condition. During adolescence, grease glands in the skin produce extra grease in response to normal amounts of sex hormones in the body which can cause blocked pores (i.e., blackheads). When this happens, the pores are invaded by bacteria. As a result, certain chemicals are produced which go into deeper parts of the skin to produce red spots filled with pus, called acne.

The common side effects of Derlin are irritation, swollen, pale red bumps and dryness. A scaly skin rash may occur rarely with the use of Derlin. You must consult your doctor if it bothers you.

Be careful not to get Derlin into your eyes or mouth. If you happen to get it in your eyes, rinse off with plenty of water immediately and contact your doctor. You must not use Derlin if you are allergic to it or any of its ingredients. Tell your doctor if you notice any allergic reaction while using it for the first time. Inform your doctor if you are taking any medicines regularly, to prevent any allergic reaction with other medicines. Do not cover the area being treated with Derlin with a bandage, as this may increase absorption of this medicine and increase the side effects. Do not use more than what is recommended to relieve your symptoms faster. Using more than what is advised will only increase the side effects. Let your doctor know if you are planning to conceive. Pregnant and breastfeeding mothers should use Derlin only if prescribed by the doctor.

Before using Derlin, clean and dry the affected area. Gently and thoroughly massage it into the skin. Be careful not to get the medication in your eyes or mouth. If Derlin gets in your eyes accidentally, wash with plenty of water and call your doctor if your eyes are irritated.

Derlin is effective if used in the dose and duration advised by your doctor. Do not stop taking it even if you see improvement in your condition. If you stop using Derlin too early, the symptoms may return or worsen.
