What does UVB phototherapy mean? Is methotrexate safe during pregnancy? Can vitamin D treat psoriasis? Learn more about some of the medications, issues, and side effects of treating psoriasis.
What psoriasis medications can be taken during pregnancy?
If you have psoriasis and plan on becoming pregnant, you should talk to your doctor about the best medication for you. Many psoriasis medications are not suitable for those who are pregnant and nursing. Some must never be used during pregnancy. People who are pregnant or are planning to get pregnant must not use retinoids applied to the skin (e.g., tazarotene) or taken by mouth (e.g., acitretin), hydroxyurea, 6-thioguanine, or methotrexate, as they pose a risk of birth defects. Topical (skin-applied) corticosteroids, such as those that have low or mid-potency, may be used. For other medications, the safety of use during pregnancy has not been established. Speak to your doctor to find out what options are available.
Is it true that vitamin D can treat psoriasis?
Not exactly. However, there is an effective psoriasis treatment called calcipotriol that has a structure similar to that of vitamin D3. It’s available as a cream, ointment, or scalp solution. The beneficial effects of this medication may take 6 to 8 weeks to show best results, so don’t stop using it until you’ve given it enough time to work. The fastest improvement is seen when this medication is used together with topical corticosteroids. Pre-mixed combination products are also available. Calcipotriol shouldn’t be used on the face. You should limit the amount you use to 100 g per week to prevent a potential side effect called hypercalcemia – a higher-than-normal amount of calcium in the blood.
What is UVB phototherapy?
UVB is a form of phototherapy that stands for ultraviolet light B. It involves exposing your skin to a source of UVB radiation for a set period, on a regular schedule. There are several types of UVB treatments such as at-home treatments or laser therapy. The main side effects of UVB phototherapy are mild sunburn reactions. Phototherapy can increase the risk of skin cancer.
