Panretin belongs to a group of medicines that are related to vitamin A and known as retinoids

Panretin is used in patients with AIDS-related Kaposi?s sarcoma (KS) and is for the treatment of the KS lesions:

  • that are on the skin only;
  • which have not responded to your HIV treatment;
  • where the skin or lesion is not broken;
  • where the surrounding skin is not swollen;
  • or if your doctor thinks that other treatments are not suitable for you.

Panretin does not treat KS that is inside the body.

How to apply Panretin: For cutaneous use (on the skin) only

Apply Panretin twice a day to start with, once in the morning and once in the evening. After that, your doctor will decide how often you should apply the gel depending on the response of your KS and any side effects.

Apply Panretin to your KS lesions using a clean finger. Place a generous coating of gel over the whole surface of each lesion that you want to treat. You do not need to rub the gel into the lesion. You need to avoid applying the gel to the healthy skin around the lesion. Carefully applying the gel only to the area of the KS lesion will help to lessen any irritation or redness that may occur. Proper application will leave some gel visible on the surface of the lesion when you are finished.

  • Immediately after application, wipe the finger(s) you have used to apply the gel and any healthy skin touched by the gel with a disposable tissue. Wash your hands using soap and water and wipe the healthy skin touched by the gel.
  • Allow the gel to dry for three to five minutes before covering a treated area with loose clothing. Do not cover the treated lesions with any bandage or other material.
  • A mild soap is recommended when bathing or showering.
  • If you think that the effect of Panretin is too strong or too weak, talk to your doctor or pharmacist.
  • Avoid showering, bathing, or swimming for at least three hours after any application.
  • Avoid scratching the treated areas.
  • Panretin contains alcohol. Keep away from naked flame.

Your doctor will tell you how long your treatment will last.

  • Do not be discouraged if you do not see immediate improvement.
  • It may take up to 12 weeks for any improvement to show.
  • Do not stop treatment at the first sign of improvement.
  • You may need to reduce the number of daily applications, or stop using Panretin for a short while, if you develop unwanted skin effects. It is important that you consult your doctor, who will tell you what to do.
