Methenamine/sodium salicylate, sold under the brand name Cystex among others, is a combination drug comprising methenamine and sodium salicylate. Methenamine serves as a urinary antiseptic and antibacterial agent, while sodium salicylate is a nonsteroidal anti-inflammatory drug (NSAID) and analgesic. The combination is used for the treatment and prevention of urinary tract infection (UTI) symptoms. [1] [2] [3] [4]

Medical uses

Methenamine, whether used alone or in combination with sodium salicylate, is considered an alternative to antibiotics for the treatment and prevention of UTIs and related symptoms. [5] [1] Unlike antibiotics, methenamine does not contribute to the risk of bacterial resistance. [1] [2] [6]

Available forms

The drug is available over-the-counter (OTC), including in the United States, and is typically taken by mouth three times per day. [1] [2] [3] [4]

Methenamine/sodium salicylate is marketed under several brand names, including Cystex Urinary Pain Relief, AZO Urinary Tract Defense, Uro-Pain Dual Action, and CVS Antibacterial Plus Urinary Pain Relief. [7] [4] Some formulations also include phenazopyridine and are marketed as products like the All-In-One UTI Emergency Kit. [4]

Comparison with methenamine

Methenamine is also available as a prescription drug and is used alone to prevent recurrent UTIs. [1] [8] [5] Clinical evidence supports its efficacy for this indication. [1] [8] [5] [9] Prescription methenamine is usually administered as the hippuric acid or mandelic acid salt, while the OTC methenamine/sodium salicylate formulation uses methenamine as the free base. [1] [3] [10] [4]

Compared to prescription methenamine, the OTC combination formulation contains lower doses of methenamine. This OTC version has been studied less extensively, and limited clinical data are available to guide its use. [2] [1]

A urinary tract infection (UTI) is an infection that affects a part of the urinary tract. Lower urinary tract infections may involve the bladder (cystitis) or urethra (urethritis) while upper urinary tract infections affect the kidney (pyelonephritis). Symptoms from a lower urinary tract infection include suprapubic pain, painful urination (dysuria), frequency and urgency of urination despite having an empty bladder. Symptoms of a kidney infection, on the other hand, are more systemic and include fever or flank pain usually in addition to the symptoms of a lower UTI. Rarely, the urine may appear bloody. Symptoms may be vague or non-specific at the extremities of age.

Uromune, also known by its developmental code name MV-140, is a polyvalent bacterial vaccine which is used and is being developed for prevention of recurrent urinary tract infections (UTIs). In clinical studies, it has been found to reduce total number of UTIs by about 70%, to increase UTI-free rates from around 25% to 57%, and to increase time to next UTI from about 1.6 months to 9.0 months. It has also been found to reduce subjective UTI symptoms, reduce antibiotic use, and improve quality of life. The effectiveness of the vaccine appears to decrease with time, which might warrant readministration. Uromune is used as a sublingual spray once daily for 3 months.
