What is Magnesium Salicylate used for?

Magnesium Salicylate is used to relieve pain from various conditions. It also reduces pain, swelling, and joint stiffness from arthritis. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).

How should I take Magnesium Salicylate?

If you are taking the over-the-counter product, read all directions on the product package before taking this medication. Take this medication by mouth, usually 3 to 4 times daily with a full glass of water (240 milliliters) or as directed by your doctor. Do not lie down for at least 10 minutes after taking this drug. If stomach upset occurs while taking this medication, take it with food, milk, or an antacid.

To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Do not take the over-the-counter product for more than 10 days unless otherwise directed. For ongoing conditions such as arthritis, continue taking this medication as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.

If you are taking this drug “as needed” (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the symptoms have worsened, the medicine may not work as well.
