Nalixone 500mg/50mg: Uses, Side Effects, Interactions
Nalixone is a Mexican antibacterial medication that consists of Nalidixic Acid and Phenazopyridine Hydrochloride. Nalidixic acid is a quinolone antibacterial agent for oral administration. Nalidixic acid has marked antibacterial activity against gram-negative bacteria including Enterobacter species, Escherichia coli, Morganella Morganii; Proteus Mirabilis, Proteus vulgaris, and Providencia rettgeri.
Phenazopyridine on the other hand is a pain reliever that affects the lower part of your urinary tract (bladder and urethra). Together, they are used to treat urinary symptoms such as pain or burning, increased urination, and increased urge to urinate.
To reduce the development of drug-resistant bacteria and maintain effectiveness of Nalixone and other antibacterial drugs, Nalixone should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered when selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Nalixone Safety Information
Central Nervous System (CNS) effects including convulsions, increased intracranial pressure, and toxic psychosis has been reported with nalidixic acid therapy. Convulsive seizures have been reported with other drugs in this class. Quinolones may also cause CNS stimulation which may lead to tremors, restlessness, lightheadedness, confusion, and hallucinations. Therefore, nalidixic acid should be used with caution in patients with known or suspected CNS disorders, such as cerebral arteriosclerosis or epilepsy, or other factors which predispose seizures. If these reactions occur in patients receiving nalidixic acid, the drug should be discontinued and appropriate measures instituted.
Serious and occasionally fatal hypersensitivity (anaphylactoid) reactions, some following the first dose, have been reported in patients receiving quinolone therapy. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, tingling, pharyngeal or facial edema, dyspnea, urticaria, and itching. Only a few patients had a history of hypersensitivity reactions. Serious anaphylactoid reactions required immediate emergency treatment with epinephrine. Oxygen, intravenous steroids, and airway management, including intubation, should be administered as indicated.
Nalidixic acid and other members of the quinolone drug class have been shown to cause arthropathy in juvenile animals.
