About Rifazen 400mg Tablet
Rifazen 400mg Tablet is classified as an antibiotic that is primarily utilized in the treatment of hepatic encephalopathy, a condition that arises when the liver is unable to effectively eliminate harmful toxins from the bloodstream, thereby resulting in potential brain damage. Additionally, this medication is also employed in the management of infectious diarrhea. The mechanism of action of Rifazen involves the eradication and prevention of the proliferation of detrimental bacteria within the intestines.
This medication can be administered independently or in conjunction with other therapeutic agents. For optimal efficacy, it is recommended to consume Rifazen with or without food, ideally at the same time each day. Proper usage entails adhering to the prescribed dosage and duration as directed by a healthcare provider.

Potential side effects associated with Rifazen may include symptoms such as vomiting, headache, dizziness, nausea, skin rashes, joint discomfort, and feelings of depression. It is noteworthy that these adverse reactions are typically transient in nature and tend to subside as the body adjusts to the medication.

Notably, the discoloration of urine to a reddish hue can occur with Rifazen usage, which is considered a normal and benign occurrence.
Prior to the initiation of Rifazen treatment, individuals are advised to inform their healthcare provider about specific circumstances such as pregnancy, breastfeeding status, preexisting liver, kidney, or cardiac conditions, as well as any known allergies to medications.
