Altreno: Uses, Side Effects and Dosage

What is ALTRENO used for?

ALTRENO is applied to the skin to treat acne. Acne is a condition in which the skin has blackheads, whiteheads, papules, pustules, or cysts.

ALTRENO can be used in patients 9 years of age and older.

ALTRENO has moisturizers which may help the dryness of the skin.

How does ALTRENO work?

ALTRENO belongs to a group of medicines called retinoids. It works by causing the outer skin layer to grow faster and becomes thinner. It is also associated with the thickening of the epidermis (the outermost of the three layers that make up the skin). This helps prevent build-up of debris in the oil glands of the skin which can cause acne.

If you are allergic to the medicinal ingredients in ALTRENO or of any of its ingredients (see “What are the ingredients in ALTRENO”)

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take ALTRENO. Talk about any health conditions or problems you may have, including if you:

• Have sensitive skin

Other warnings you should know about:

Skin

• Skin reactions such as site dryness, peeling, burning, itching, stinging, redness, and eye irritation may occur during the first one or two weeks of use. These reactions can be minimized by following the instructions carefully. Should the effects become severe, discontinue use, and consult your doctor.
• ALTRENO can make your skin more sensitive and increase the possibility of sunburn. Minimize exposure of areas treated with ALTRENO to sunlight or sunlamps during treatment. Wear protective clothing whenever you have to go out in the sun, even on hazy days. Use a sunscreen on areas treated with ALTRENO.
• Avoid excessive exposure to wind or cold as skin treated with ALTRENO may be more sensitive to these extremes.
• Hyper – or hypopigmentation (darkening or lightening of the skin) has occasionally been reported when the product is used to the point of severe irritation. This side effect is reversible when the medication is stopped or discontinued.

General Use

• Use ALTRENO as your doctor instructed. Excessive medication will not produce better results and marked redness, peeling and discomfort may occur. Apply a moisturizer or a moisturizer with sunscreen that will not aggravate your acne (this is know as non-comedogenic) every morning after you wash.
• Do not apply on eyes eyelids, angles of the nose, mouth, mucous membranes, or other areas where treatment is not intended.
• Do not apply on skin that is severely inflamed, sunburnt, or has open lesions or eczema.
• Do not use if reactions are severe and the skin becomes extremely red, swollen and crusted.
• Avoid using medicated or abrasive topical products with a high concentration of alcohol, spices, or lime. They cause needless stinging and burning on treated skin.
• Cosmetic can be used. Clean the skin thoroughly of any cosmetics before ALTRENO use.
• Avoid hair removal procedures before ALTRENO use.
• Keep tube tightly closed.

Pregnancy and breast-feeding

• Consult your doctor for contraceptive counselling. ALTRENO should be used by women of childbearing years only after contraceptive counselling.
• Do not use if you are pregnant, plan to become pregnant, or think you are pregnant. It may harm your unborn baby.
• Talk to your healthcare professional if you are breast-feeding. It is not known if ALTRENO passes in breast milk.
• Do not apply directly to the nipple and areola if you are breast-feeding

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

How to take ALTRENO:

ALTRENO should only be applied to your skin.

1. 1. Wash with a mild soap and dry skin gently. Do not wash more than twice per day.
2. 2. Wait twenty to thirty minutes before applying medication so that your skin is completely dry.
3. 3. Apply ALTRENO once daily as directed by your doctor.
4. 4. Squeeze a small amount (about the size of a pea) on your fingertip. Spread on the skin where acne lesions appear, using enough to cover the entire affected area, using a gauze swab, cotton wool or the tips of clean fingers. Only use enough medication to cover the affected areas lightly.
5. 5. Keep the medication away from the corners of the nose, mouth, eyes and mucous membranes or other areas where treatment is not intended. Spread away from these areas when applying.
6. 6. Keep container closed when not in use.
7. 7. The medication should become invisible almost immediately. If it is still visible or if dry flaking occurs within a minute or so, you are using too much.
8. 8. If your doctor has prescribed another topical acne treatment (i.e. benzoyl peroxide or topical antibiotic), do not apply ALTRENO at the same time of day as the other products.

After 3 to 6 weeks of therapy some patients notice new blemishes. At this stage it is very important to continue using ALTRENO. Do not expect an overnight cure. With the use of ALTRENO, you will notice a gradual improvement over eight to twelve weeks.

Usual dose:

Apply daily to the affected areas after cleansing with a mild, non-medicated soap and water.

ALTRENO can be used in patients 9 years of age and older.

Overdose:

In case of accidental oral ingestion, in addition to the boxed warning above, if you are in your childbearing years discuss with your doctor if a pregnancy test should be done.

Missed Dose:

If you miss a dose, it is not necessary to make up the missed dose. Just wait until the next evening and use ALTRENO as usual. Apply the same amount you usually would. Do not apply an extra amount.
