Ribavirin Dosage
Ribavirin is used to treat several viral infections, with the dosage varying based on the condition being treated. Always consult your healthcare provider before making any changes to your dosage. Our telemedicine providers are available to assist with any questions or concerns.
Ribavirin for Hepatitis C
Ribavirin is typically used in combination with other medications, such as interferon or direct-acting antivirals (DAAs). The usual adult dose ranges from 800 to 1200 mg per day, divided into two doses, and should be taken with food. Treatment duration can vary from 24 to 48 weeks, depending on the specific regimen prescribed.
Ribavirin for Respiratory Syncytial Virus (RSV)
For RSV, Ribavirin is administered as an aerosolized solution. The recommended dose is 6 grams per day, delivered via a nebulizer for 12 to 18 hours daily over 3 to 7 days. This treatment is typically reserved for severe cases in hospitalized patients.
Ribavirin for Hemorrhagic Fever (e.g., Lassa Fever, Crimean-Congo Hemorrhagic Fever, Hantavirus Pulmonary Syndrome)
The dosage for hemorrhagic fevers varies depending on the specific virus. For Lassa Fever, the recommended dose is 30 mg/kg intravenously (IV) as a loading dose, followed by 15 mg/kg IV every 6 hours for 4 days, then 7.5 mg/kg IV every 8 hours for 6 days. For other hemorrhagic fevers, consult your healthcare provider for specific dosing recommendations.
Ribavirin for Chronic Hepatitis B
Ribavirin is not commonly used as a first-line treatment for Hepatitis B but may be prescribed in certain cases. The typical dose is similar to that for Hepatitis C, around 800 to 1200 mg per day, taken in divided doses with food. The duration of treatment depends on the patient’s response to therapy.
Ribavirin for West Nile Virus, Yellow Fever, Dengue Fever
Ribavirin is not routinely used for these infections but may be considered in severe cases. Dosing is not well-established, and treatment should be guided by a healthcare provider experienced in managing these infections.
Dosage Forms and Strengths
Oral Tablets: 200 mg, 400 mg, 600 mg
Aerosolized Solution: 6 grams per vial (for inhalation)
Capsules: 200 mg
Administration Instructions for Ribavirin
Ribavirin should be taken with food to improve absorption and reduce the risk of stomach upset. If using the aerosolized form for RSV, it will be administered through a nebulizer in a hospital setting. Follow your healthcare provider’s instructions carefully. Do not stop taking Ribavirin without consulting your doctor, as stopping early can lead to a relapse of the infection.
Contraindications for Ribavirin
A contraindication is a specific situation where a medication should not be used due to potential harm. Ribavirin has several contraindications, meaning certain conditions or factors make it unsafe for some individuals.
Key Contraindications for Ribavirin
Pregnancy: Ribavirin can cause severe birth defects or the death of an unborn baby. It is absolutely contraindicated in pregnant women or those planning to become pregnant. Both men and women must use effective contraception during treatment and for at least 6 months after stopping the medication.
Severe kidney disease: Ribavirin is processed by the kidneys, and individuals with severe kidney disease may not clear the drug effectively, leading to toxic levels in the body.
Autoimmune hepatitis: Ribavirin can worsen autoimmune hepatitis, a condition where the immune system attacks the liver, causing severe liver damage.
Hemoglobinopathies (e.g., sickle cell anemia, thalassemia): Ribavirin can cause hemolytic anemia, a condition where red blood cells are destroyed faster than they can be produced. People with hemoglobinopathies are at higher risk of this complication.
Uncontrolled heart disease: Ribavirin can cause anemia, which may worsen heart conditions, especially in individuals with a history of heart attacks or heart failure.
Ribavirin Drug Interactions
Ribavirin can interact with other medications, increasing the risk of side effects or reducing the effectiveness of treatment. Be sure to inform your healthcare provider about all medications you are taking, including over-the-counter drugs and supplements.
Medications that Interact with Ribavirin
Azathioprine (Imuran): This immunosuppressant can increase the risk of bone marrow suppression when taken with Ribavirin.
Didanosine (Videx): Taking Ribavirin with this antiretroviral medication can increase the risk of serious side effects, such as liver failure and pancreatitis.
Abacavir (Ziagen): Ribavirin may reduce the effectiveness of this HIV medication, potentially leading to treatment failure.
Zidovudine (Retrovir): This HIV medication can increase the risk of anemia when combined with Ribavirin.

Ribavirin in Pregnancy
Is it Safe to Take Ribavirin During Pregnancy?
No, Ribavirin is not safe during pregnancy. It is classified as a Category X drug, which means it can cause severe birth defects or even fetal death. Women who are pregnant or planning to become pregnant should avoid taking Ribavirin. Both men and women must use effective contraception during treatment and for at least six months after stopping the medication. If you are pregnant or become pregnant while taking Ribavirin, contact your healthcare provider immediately.
Ribavirin While Breastfeeding
Is it Safe to Take Ribavirin While Breastfeeding?
No, Ribavirin is not recommended while breastfeeding. It is unclear whether Ribavirin passes into breast milk, but due to the potential for serious side effects in a nursing infant, breastfeeding should be avoided while taking this medication. If you are breastfeeding or planning to breastfeed, consult your healthcare provider to discuss alternative treatments.
Estimated Cost of Ribavirin Medication
The cost of a 30-day supply of Ribavirin can vary depending on the dosage and the pharmacy. Without insurance, using a GoodRx coupon, the price for a 30-day supply of Ribavirin (200 mg tablets) typically ranges from $50 to $100.
