Frequently Asked Questions about Plaquenil

1. How long does it take Plaquenil to work for lupus?

Plaquenil is a DMARD, which stands for Disease-Modifying Anti-Rheumatic Drugs. It works slowly and may take one to three months before you notice any benefit. Since it’s a long-term treatment, continue taking it for the prescribed duration. Your doctor may also recommend other medicines in addition to Plaquenil for pain and stiffness.

2. How to take Plaquenil?

Your doctor will recommend a suitable dosage considering your body weight. You may be required to take Plaquenil as a pill one or two times a day. Avoid taking this medicine on an empty stomach as it can upset the stomach.

3. Is Plaquenil a steroid?

Plaquenil is not a steroid but a steroid-sparing agent. Steroid drugs, when taken long-term, can lead to various side effects such as fluid retention, elevated blood sugars, etc. However, the risk of long-term effects is reduced when steroid-sparing drugs are used.

9. Is Plaquenil an anti-inflammatory?

10. Why is Plaquenil bad for the eyes?

Plaquenil causes changes in the pigment of the central portion of the retina (macula), which is responsible for color vision and allows us to see fine details. Plaquenil binds to the retinal pigment cells, which over time cause adverse changes in the vision. The patient may start seeing the objects as blurry or distorted.
Plaquenil is prescribed in selected conditions only. It should not be shared with others. It may also interact with other medications. Hence, inform your doctor about the list of medicines, supplements, and non-prescription drugs you use.
