Methenamine, available under the brand names Hiprex and Urex, is a prescription medication used to prevent or treat chronic urinary tract infections (UTIs). It belongs to the drug class known as antibacterial agents. Methenamine releases formaldehyde in the urine, inhibiting cell division, and damaging bacterial cells' protein. This action eliminates the bacteria that can lead to infection.

This medication is available in brand-name and generic versions, requiring a prescription from a licensed healthcare provider.

Methenamine is primarily prescribed for preventing and treating chronic urinary tract infections (UTIs).

Methenamine may also be prescribed for other conditions or by urologists and specialists in certain cases.

Before starting treatment with methenamine, inform your healthcare provider about any existing medical conditions, allergies, or other medications you are taking. This includes prescription drugs, over-the-counter medications, and dietary supplements, as they may interact with methenamine.

If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare provider before using methenamine to assess potential risks and benefits.

It is crucial to follow your healthcare provider's instructions regarding dosing and any other recommendations related to taking methenamine. Typically, methenamine is taken with or without food and should be accompanied by adequate fluid intake.
