This is a combination product that contains 2 medications: calcipotriol and betamethasone. This medication is used to treat psoriasis. Calcipotriol belongs to the class of medications known as vitamin D analogues and works by controlling the excessive production of skin cells seen in psoriasis. Betamethasone belongs to the class of medications known as corticosteroids and works by reducing itching and inflammation.

All forms of this medication are used to treat psoriasis that develops on the body. The gel and foam forms of this medication may also be used to treat psoriasis that has developed on the scalp.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

This medication is applied once daily to affected areas. Do not apply the medication to areas that do not have psoriasis. This medication may be used for up to 4 weeks. Do not use more than 15 grams of medication per day.

Shake the can for a few seconds before using. Hold the can about 3 cm above the skin and spray. Spraying calcipotriol-betamethasone for about 2 seconds will cover an area of skin that is about the size of the palm of an adult's hand. Gently rub the foam into the affected skin areas. If you are using this medication on your scalp, spray it into the palm of your hand first, and then apply it to affected areas of the scalp with your fingertips.

After applying the medication to the affected areas, do not wash it off. The medication needs to stay in contact with the affected areas in order to work.

Do not apply this medication on the face, large areas of damaged skin, in skin folds, the underarms, genitals, groin, or under dressings that do not breathe. Use this medication in a well-ventilated area and avoid breathing it in. Wash your hands after applying calcipotriol - betamethasone so that you do not get the medication on other parts of your body. Avoid getting the medication in your eyes or on your face. If the medication gets on your face, wash it off. If it gets in your eyes, flush the eyes with plenty of water. Do not take this medication by mouth.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, apply it as soon as possible and continue with your regular schedule.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Absorption: Applying this medication over large areas of damaged skin, in skin folds, or under dressings that do not breathe could promote the absorption of betamethasone into the blood. This could cause unwanted effects similar to those that happen after taking oral (by mouth) corticosteroid medications for long periods of time. If you notice symptoms of using steroid medications for long periods of time, such as weakness, increased urination, increased thirst, fatigue, or weight loss, contact your doctor as soon as possible.

High calcium in the blood: If this medication is used for severe psoriasis over a large area of skin or is used more than the maximum recommended weekly amount of 100 g of ointment, gel, or foam, there is a risk of developing high calcium levels in the blood. Your doctor may monitor your blood calcium levels regularly by doing blood tests while you are using this medication.

Kidney function: If you have decreased kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: If you have decreased liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Medical treatment: Inform all health professionals involved in your care that you have been using a topical (skin-applied) corticosteroid.

Prolonged use: Using topical corticosteroid medications for a long period of time can cause skin to thin or soften or cause stretch marks. Your doctor may recommend you stop using this medication once in a while or to apply to one area of the body at a time. Suddenly stopping corticosteroid medication may cause psoriasis to return.

Skin cancer: When calcipotriol is used with ultraviolet radiation (some psoriasis treatments use light therapy), there may be an increased risk of developing skin cancer caused by ultraviolet radiation. Calcipotriol alone does not cause cancer. While using this medication, avoid exposure to sunlight and artificial ultraviolet light (e.g., tanning beds).

Use on the face: This medication should not be used on any part of the face since this may cause redness, irritation, and itchiness. If any of these skin reactions develop, you should stop using this medication and contact your doctor immediately. Wash your hands thoroughly after applying this medication to the affected areas and avoid touching any part of your face with your hands.

Using other corticosteroids: Betamethasone dipropionate is a potent corticosteroid and should not be used at the same time as other corticosteroid medications, particularly on the scalp. If you have been prescribed another scalp product containing corticosteroids, contact your doctor to determine which product you should be using.

Pregnancy: This medication should not be used during pregnancy. If you become pregnant while using this medication, contact your doctor immediately.

Breast-feeding: Betamethasone passes into breast milk. It is not known if calcipotriol passes into breast milk. If you are breast-feeding and are using this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using the ointment and gel forms of this medication have not been established for children. The topical foam form of calcipotriol-betamethasone may be safely used by children and adolescents 12 years of age and older.

• change how you are taking one or both of the medications, or
• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
