Purifen 400 mg is an antibiotic used to treat a variety of bacterial infections by targeting and inhibiting the growth of harmful bacteria in the body. It is commonly prescribed for infections such as respiratory tract infections, urinary tract infections, and skin infections. The medication works by disrupting bacterial cell function, helping to alleviate symptoms like fever, pain, and inflammation. To ensure effectiveness and prevent the development of antibiotic resistance, it is crucial to take Purifen exactly as prescribed by a healthcare provider, completing the full course of treatment even if symptoms improve before the medication is finished. As with all antibiotics, consulting a doctor before use is recommended to ensure the appropriate treatment and avoid potential interactions or side effects.
