Dosage & Administration

Standard regimens per Canadian guidelines

Rebetol, containing ribavirin, is primarily prescribed for the treatment of chronic hepatitis C in combination with interferon. For adult patients, the recommended dosages are as follows:

• If body weight is less than 75 kg, a total of 1000 mg/day is prescribed, divided into 400 mg in the morning and 600 mg in the evening.
• For those weighing 75 kg or more, the dosage increases to 1200 mg/day, split into 600 mg doses both in the morning and evening.

This treatment strategy often spans 24 to 48 weeks depending on the specific genotype of the hepatitis virus, emphasizing the importance of careful monitoring throughout the process.

Adjustments by patient type

Dosage adjustments are essential for certain populations:

• Children: Dosage is weight-based, typically around 15 mg/kg/day (split into two doses with food).
• Elderly: Caution is advised as reduced renal function may necessitate dosage modifications.
• Renal impairment: Patients with a creatinine clearance below 50 mL/min should avoid the medication, or the dose may need to be halved.
• Hepatic impairment: For individuals with advanced liver disease, Rebetol is not recommended, and those with mild to moderate impairment require careful oversight.

Contraindications & Side Effects

Common

Health Canada outlines several common side effects associated with Rebetol. Frequent complaints include:

• Fatigue
• Headaches
• Fever and chills
• Nausea and appetite loss

Patients may also experience insomnia, irritability, and skin-related issues. While these side effects are generally classified as mild to moderate, they can disrupt daily life and warrant supportive care.

Rare but serious

More serious, albeit rare, side effects include hematological issues like severe anemia and neutropenia, alongside potential psychiatric effects including depression and anxiety. According to Canadian pharmacovigilance data, there are absolute contraindications for pregnant women due to teratogenic risks, as well as those with severe renal impairment and certain blood disorders. Monitoring is crucial for those with cardiac issues or significant psychiatric histories.
