    Precautions

    Gold compounds may cause some people to become more sensitive to sunlight than they are normally. These people may break out in a rash after being in the sun, or a skin rash that is already present may become worse. To protect yourself, it is best to:

    • Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.
    • Wear protective clothing.
    • Ask your doctor if you may apply a sun block product. Products that have a skin protection factor (SPF) of at least 15 work best, but some patients may require a product with a higher SPF number, especially if they have a fair complexion.
    • Do not use a sunlamp or tanning bed or booth.

    If you have a severe reaction from the sun, check with your doctor.

If any of these effects continue or become worse, or if you notice any other effects within 10 minutes or so after receiving an injection, tell your health care professional right away.
    • Joint pain may occur for 1 or 2 days after you receive an injection of this medicine. This effect usually disappears after the first few injections. However, if this continues or is bothersome, check with your doctor.
