Are there any other precautions or warnings for this medication?

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 circulation. This could produce unwanted effects similar to those seen 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 with a large area of skin involvement or is used more than the maximum recommended weekly amount of 100 g of ointment and gel, 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.

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 (e.g., 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. People using calcipotriol - betamethasone should wash their hands thoroughly after applying to the affected areas and avoid touching any part of the face with their 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 a breast-feeding mother and are taking this medication, it may affect your baby. This medication is not recommended for use in breast-feeding women.

Children: The safety and effectiveness of using this medication have not been established for children.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

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

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
