- This medicine can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. Do not use it just before or after heart bypass surgery (coronary artery bypass graft, or CABG).
- This medicine may cause stomach or intestinal bleeding, which can be fatal. This can happen without warning, especially in older adults.
- Do not give this medicine to a child or teenager with a fever, flu symptoms, or chickenpox, since salicylates can cause Reye's syndrome, a serious and sometimes fatal condition in children.
- Do not use if you are allergic to methenamine, sodium salicylate, or aspirin.
- Ask a doctor before using this medicine if you are pregnant. If you are pregnant, you should not take it unless your doctor tells you to, since taking an NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.

- Kidney disease requires medical review before use.
