Walgadox 100 Injection contains Doxycycline 100 mg, a broad-spectrum tetracycline antibiotic effective against a wide range of bacterial infections. It acts by inhibiting protein synthesis in susceptible bacteria, thereby exerting a bacteriostatic effect. Walgadox 100 Injection is indicated for the treatment of respiratory tract infections, urinary tract infections, skin and soft tissue infections, sexually transmitted infections, and certain atypical infections such as Lyme disease and rickettsial infections. It is also used in the management of malaria as part of combination therapy. Administered via intramuscular or intravenous routes, this formulation ensures rapid systemic absorption and is suitable for patients unable to take oral medications. Dosage and duration of therapy should be tailored according to the severity of infection, patient age, renal and hepatic function, and clinical response. Common adverse effects may include gastrointestinal disturbances, photosensitivity, and hypersensitivity reactions. Caution is advised in pregnant or lactating women and in children under eight years due to potential effects on bone and teeth development.
