Magnesium Salicylate

Warning

Nonsteroidal anti-inflammatory drugs (including magnesium salicylate) may rarely increase the risk for a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).

Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect.

Stop taking this medication and get medical help right away if you notice any of these rare but serious side effects: stomach/abdominal pain that doesn't go away, black/tarry stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, trouble speaking, sudden vision changes.

Talk to your doctor or pharmacist about the benefits and risks of taking this drug.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: asthma (including a history of worsening breathing after taking aspirin or other NSAIDs), kidney disease, liver disease, diabetes, stomach/intestine/esophagus problems (such as bleeding, ulcers, recurring heartburn), heart disease (such as heart failure, history of heart attack), high blood pressure, stroke, swelling of the ankles/feet/hands, dehydration, blood disorders (such as anemia), bleeding/clotting problems, growths in the nose (nasal polyps), certain genetic conditions (G-6-PD deficiency, pyruvate kinase deficiency).

It is not recommended for use in pregnancy from 20 weeks until delivery. If your doctor decides that you need to use this medication between 20 and 30 weeks of pregnancy, you should use the lowest effective dose for the shortest possible time.
