Q: How does Mavyret work?

Mechanism of Action Mavyret is a direct-acting antiviral (DAA) medication. It is made of two drugs, glecaprevir and pibrentasvir, which interfere with the proteins the hepatitis C virus (HCV) uses to reproduce. How the Ingredients Work Glecaprevir: This is an NS3/4A protease inhibitor. The virus uses the NS3/4A protease enzyme to cut long protein chains into smaller pieces that are necessary for the virus to make copies of itself. Glecaprevir blocks this enzyme, stopping the replication process. Pibrentasvir: This is an NS5A inhibitor. It targets the NS5A protein, which is required for the virus to copy its genetic material and assemble new virus particles. By attacking the virus at these two different stages, Mavyret prevents the virus from multiplying. This reduces the amount of virus in the body, with the goal of clearing the infection completely.

Q: What is the dosage of Mavyret and how do I take it?

How to Take Mavyret Mavyret is available as tablets or as oral pellets in packets. It is typically taken once per day. It is important to take this medication with food to ensure it is absorbed properly by the body. For the best results, try to take the dose at the same time each day. Administration Instructions Tablets: Tablets should be swallowed whole. Do not crush or chew the tablets. Oral Pellets: Pellets are often used for children or adults who have difficulty swallowing tablets. The entire contents of the packet should be sprinkled onto a small amount of soft food with low water content, such as peanut butter, chocolate nut spread, cream cheese, or strawberry jam. The mixture should be swallowed immediately without chewing the pellets. Missed Dose If a dose is missed, it should be taken as soon as it is remembered. However, if a significant amount of time has passed since the scheduled dose, the missed dose should be skipped and the next dose taken at the regular time. Do not take two doses at the same time to make up for a missed one. If you are unsure whether to take a missed dose, contact a healthcare provider or pharmacist. Duration of Treatment It is essential to complete the full course of treatment as prescribed, even if symptoms improve or the virus is no longer detectable in the blood. Stopping the medication early may result in the treatment being less effective.

Q: Is Mavyret safe during pregnancy and breastfeeding?

Pregnancy There are no adequate and well-controlled studies on the use of Mavyret in pregnant individuals. Data from animal studies involving glecaprevir and pibrentasvir did not show a risk of birth defects or miscarriage, even at doses much higher than those used in humans. However, animal studies do not always predict how a drug will affect human pregnancy. If you are pregnant or planning to become pregnant, talk to your doctor about whether Mavyret is appropriate for you. They will help weigh the potential benefits of treating hepatitis C against any unknown risks to the developing fetus. Breastfeeding It is unknown if the active ingredients in Mavyret pass into human breast milk, how they might affect milk production, or if they have any impact on a breastfed infant. In animal studies, the components of the medication were found in the milk of lactating rats. If you are breastfeeding or planning to breastfeed, consult your healthcare provider. They can help you decide whether to continue breastfeeding or start treatment based on your clinical needs and the potential risks to the child.

Q: What forms and strengths does Mavyret come in?

Available Forms Mavyret is supplied in the following oral formulations: Tablets: These are oral tablets intended to be swallowed whole. Oral Pellets: These are small pellets contained in individual packets or sachets. They are designed to be sprinkled on a small amount of soft food, which is particularly useful for children or individuals who have difficulty swallowing tablets. Both the tablets and the oral pellets must be administered with food to ensure the medication is absorbed correctly.

Q: What is the FDA approval status of Mavyret?

FDA Approval and Indications Mavyret was approved by the U.S. Food and Drug Administration (FDA) to treat chronic hepatitis C virus (HCV) genotypes 1 through 6. It is authorized for use in adults and pediatric patients aged 3 years and older who have no cirrhosis or mild cirrhosis. It is also indicated for certain patients with genotype 1 infection who were previously treated with specific antiviral regimens. Boxed Warning Mavyret carries a boxed warning concerning the risk of hepatitis B virus (HBV) reactivation. In patients coinfected with HCV and HBV, the hepatitis B virus can become active again during or after treatment, potentially leading to severe liver damage or death. Screening for HBV infection is required before beginning therapy. Safety Warnings The FDA has issued safety alerts regarding the use of Mavyret in patients with advanced liver disease. While the drug is safe for those with no or mild liver impairment, it is not recommended for patients with moderate liver impairment and is contraindicated for those with severe liver impairment (Child-Pugh C) due to the risk of serious liver injury or liver failure.
