I'm currently taking nitrofurantoin. It says not to take antacids with magnesium trisilicate. Can I take Tums (calcium carbonate) which contain magnesium stearate?

4 doctors agree

In brief: No

Stay away from magnesium until you are done with the nitrofurantoin.
You could try a different type of anti-acid medication such as zantac (ranitidine) or prilosec.

Magnesium-containing products can interfere with nitrofurantoin absorption and therefore reduce its antibiotic effectiveness.
