Ridaura

Why is Ridaura prescribed?

Ridaura, a gold preparation, is given to help treat rheumatoid arthritis. Ridaura is taken by mouth, unlike other gold compounds, which are given by injection. It is recommended only for people who have not been helped sufficiently by nonsteroidal anti-inflammatory drugs (Anaprox, Dolobid, Indocin, Motrin, and others). Ridaura should be part of a comprehensive arthritis treatment program that includes non-drug forms of therapy.

You are most likely to benefit from Ridaura if you have active joint inflammation, especially in the early stages.

Most important fact about Ridaura

Unlike anti-inflammatory medications, Ridaura does not take effect immediately. In fact, you may have to wait for 3 to 6 months to get any benefit from Ridaura. Ridaura prevents or suppresses joint swelling, but does not cure rheumatoid arthritis.

How should you take Ridaura?

Read the patient information sheet provided with Ridaura, and take Ridaura exactly as prescribed.

You should observe good oral hygiene during therapy with Ridaura.

--If you miss a dose...

If you take 1 dose a day, take the missed dose as soon as you remember. If you do not remember until the next day, skip the dose you missed and go back to your regular schedule.

If you take more than 1 dose a day, take the missed dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule.

Ridaura side effects
