Oxsoralen 10mg capsule

This medication is typically used for psoriasis or for a disorder of the skin's pigment known as vitiligo. It may also be used for eczema, as well as for other uses. It requires a few months to take effect.

Instructions

This product is part of a treatment that includes exposure to artificial sunlight. For best results, be sure to take your medication at the recommended time before exposure.

Avoid exposure to the sun for prolonged periods during the 24 hours before treatment. After treatment, avoid sun exposure for at least eight hours, even through a window or in the presence of clouds. Avoid prolonged exposure to sunlight for at least 48 hours after treatment. If this is not possible, wear protective clothing and use sunscreen.

Wear wrap-around sunglasses to protect your eyes during daylight hours for 24 hours after treatment.

Important: Follow the instructions on the label. Do not use more of this product, or more often, than prescribed. Some food may increase skin sensitivity to sun during treatment. Avoid limes, figs, parsley, parsnips, mustard, carrots, and celery.

This medication may irritate the stomach, and should be taken with food. It is best to avoid coffee, spicy food or alcohol.

In addition to its desired action, this medication may cause some side effects, notably:

  • it may cause spots or redness of the skin;
  • it may cause dizziness -- use caution when getting up from a lying or sitting position;
  • it may cause nausea or, rarely, vomiting;
  • it may cause the eyes to become more sensitive to light -- wear sunglasses if necessary;
  • it may cause stinging or itching.

Each person may react differently to a treatment. If you think this medication may be causing side effects (including those described here, or others), talk to your doctor or pharmacist. He or she can help you to determine whether or not the medication is the source of the problem.

General notes

When meeting with any health professional, it is important for you to share the following information:

  • Your medical history and allergies (medication, food, or other);
  • If you smoke, are pregnant, are planning a pregnancy, or are breastfeeding;
  • The names of all the medications you take, whether you take them regularly or once in a while, including over-the-counter medications, vitamins, and natural health products.


It is also strongly recommended that you keep an up-to-date list of all the medications you take and carry it with you at all times. This could be useful if you have to see a health professional or need emergency care.
