About Plaquenil

Plaquenil is a brand-name prescription drug. It’s approved by the Food and Drug Administration (FDA) for the following purposes.

  • Treating lupus. With lupus, the immune system attacks healthy tissues throughout the body. This leads to inflammation that can affect joints, muscles, skin, and other organs. Doctors can prescribe Plaquenil for systemic lupus erythematosus or long-term discoid lupus erythematosus in adults.
  • Treating rheumatoid arthritis (RA). With RA, the immune system attacks your joints, typically in your wrists, hands, and knees. This leads to inflammation that can cause joint stiffness and pain. Doctors can prescribe Plaquenil for RA in adults.
  • Treating or helping prevent malaria. Malaria is caused by a parasite that typically spreads to a person through a mosquito bite. This can lead to symptoms such as fever or chills. Doctors can prescribe Plaquenil for this use in adults and children of any age who weigh at least 31 kilograms (kg), which is about 68 pounds (lb).

For details about these conditions and how the drug treats them, see the “Plaquenil: Uses” section below.

Plaquenil: Generic

Plaquenil is a brand-name medication. It contains the active drug hydroxychloroquine, which also comes in a generic form. A generic is an identical copy of the active drug found in a brand-name medication.

The Food and Drug Administration (FDA) ensures that generic drugs are as safe and effective as their original drug. Generics tend to be less expensive than brand-name drugs.

If you’d like to know about the generic version of Plaquenil, ask your doctor or pharmacist. They can tell you if the generic medication comes in forms and strengths recommended for your condition.

Plaquenil: Side effects

Keep in mind that Plaquenil was approved by the Food and Drug Administration (FDA) in 1955. At that time, the process for approving medications was not as thorough as it is today.

For this reason, it isn’t known for certain whether the side effects below occurred in clinical studies.

Note: The FDA tracks side effects of drugs it has approved. If you would like to notify the FDA about a side effect you’ve had with Plaquenil, you can do so through MedWatch.

Plaquenil: Uses

Prescription drugs, such as Plaquenil, are approved by the Food and Drug Administration (FDA) to treat certain conditions. Doctors sometimes prescribe drugs off-label for other conditions. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved for.

Plaquenil: Questions you may have

Here are some common questions about Plaquenil and brief answers to them. If you’d like to know more about these topics, ask your doctor.

Does Plaquenil cause weight gain?

It isn’t likely. Weight gain wasn’t reported as a side effect with Plaquenil.

However, weight loss has been reported since the drug became available for use.

To learn more about weight gain and Plaquenil, talk with your doctor. They can suggest ways to reach or maintain a weight that is healthy for you while taking the drug.

Will I have side effects when stopping Plaquenil?

Side effects aren’t likely to happen when stopping Plaquenil.

However, Plaquenil helps manage the symptoms of lupus and rheumatoid arthritis (RA). So stopping Plaquenil treatment could cause the symptoms of your condition to come back or get worse.

If you’d like to stop Plaquenil treatment, talk with your doctor. If they tell you it’s safe to stop, they can recommend other ways to manage your symptoms. For example, they may prescribe a different treatment for your condition.

Is Plaquenil a steroid?

No, Plaquenil is not a steroid.

Instead, Plaquenil belongs to a class of drugs called antimalarials. The drug is used to treat and help prevent malaria. In addition, Plaquenil is also approved to treat lupus and rheumatoid arthritis.

To learn more about how the drug is used for these conditions, see the “Plaquenil: Uses” section below.

Do doctors prescribe Plaquenil for arthritis?

Plaquenil is not approved to treat osteoarthritis (OA), which is commonly called arthritis. However, doctors sometimes prescribe the drug off-label for this condition. With off-label use, doctors prescribe a drug for a purpose other than what it’s approved for.

Plaquenil isn’t approved to treat OA, but it is approved for rheumatoid arthritis (RA).

Both OA and RA cause inflammation that leads to joint stiffness and pain. OA happens because of wear and tear on your bones or joints over time. However, RA happens when your immune system attacks your joints. (For more information about RA, see “Plaquenil: Uses” above.)

If you have arthritis and are interested in taking Plaquenil, talk with your doctor. They can recommend whether Plaquenil is the right treatment for you.
