Tag: Urinary acidifiers

The normal pH of urine typically falls within a narrow range of 4.5 to 8.0. The balance can be altered by various medications, with several key drugs intentionally or unintentionally causing acidic urine.

The primary medication prescribed to make urine more acidic is methenamine, which works by converting into formaldehyde in low-pH urine to provide a local antibacterial effect. This pharmacological approach is used to prevent recurrent urinary tract infections (UTIs) and manage certain types of kidney stones.
