Descriptions


Afamelanotide implant is used to increase pain free light exposure in patients with a history of phototoxic reactions from erythropoietic protoporphyria (EPP). EPP is a rare inherited disease caused by a genetic mutation that makes your skin extremely sensitive to light. Symptoms include redness, pain, swelling, and tingling sensation of the skin.

Afamelatonide works by stimulating the production of eumelanin pigment in the skin to block the penetration of light through the skin and help prevent painful skin reactions.

This medicine is to be given only by a doctor.

This product is available in the following dosage forms:

  • Implant

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of afamelanotide implant in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of afamelanotide implant in the elderly.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other Interactions

Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Proper Use

A doctor will give you this medicine. The afamelanotide implant will be placed under your skin above your hip bone once every 2 months, before and during periods of high sunlight exposure, (eg, from spring to autumn).

You will be monitored 30 minutes after receiving the implant for any allergic reactions caused by the medicine.

Call your doctor right away if you feel the implant is not in the proper place.

Precautions

It is very important that your doctor check your progress at regular visits to make sure the implant is in the proper place and is working properly.

You may have some darkening of the skin and skin lesions while receiving this medicine. A regular full body skin examination (twice yearly) is needed to check for pre-existing and new skin lesions.

Wear protective clothing and hats and stay out of any bright light, or direct sunlight especially between the hours of 10 a.m. and 3 p.m. Avoid sunlamps and tanning beds. These would help prevent blisters, itching, rash, redness, swelling, or burning sensation of the skin.
