NuvaRing
Mavyret
NuvaRing is a vaginal ring that contains hormones to prevent pregnancy. It releases hormones over three weeks to stop you from getting pregnant.
Mavyret is a medicine used to treat hepatitis C (HCV) in adults and children 3 years and older. It contains two drugs, glecaprevir and pibrentasvir, that work together to stop the virus from multiplying.
NuvaRing is used by women of reproductive age to prevent pregnancy. It contains estrogen and progestin, which are hormones. These hormones prevent ovulation, so you don't release an egg and can't get pregnant.
Mavyret treats hepatitis C virus (HCV) genotypes 1, 2, 3, 4, 5, or 6. It can be used in people without cirrhosis or with compensated cirrhosis. Mavyret can also treat genotype 1 in people who have already been treated with certain other HCV medicines.
NuvaRing contains two hormones: etonogestrel and ethinyl estradiol. These hormones are released slowly into your body. They prevent pregnancy mainly by stopping your ovaries from releasing an egg.
Mavyret contains glecaprevir and pibrentasvir. Glecaprevir blocks a protein called NS3/4A protease that the virus needs to multiply. Pibrentasvir blocks a protein called NS5A, also needed for the virus to multiply. By blocking these proteins, Mavyret stops the hepatitis C virus from spreading in your body.

Cigarette smoking increases your risk of serious heart problems if you use hormonal birth control like NuvaRing. This risk is higher if you are over 35 and smoke more cigarettes. If you are over 35 and smoke, you should not use NuvaRing.
Mavyret can cause hepatitis B to become active again if you have had it in the past. This can cause serious liver problems, including liver failure and death. Your doctor will test you for hepatitis B before you start Mavyret. They will also monitor you during and after treatment.
Do not use NuvaRing if you are pregnant. NuvaRing can pass into breast milk and may reduce milk production. Talk to your doctor about other birth control options if you are breastfeeding.
It is not known if Mavyret will harm your unborn baby. Talk to your doctor if you are pregnant or plan to become pregnant. It is also not known if Mavyret passes into breast milk. Talk to your doctor about the best way to feed your baby if you are taking Mavyret.

ethinyl estradiol/etonogestrel is classified in the Vaginal Contraceptive Ring drug class, while glecaprevir/pibrentasvir sits within the NS3/4A/NS5A Inhibitor (HCV) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, ethinyl estradiol/etonogestrel has 0 submissions while glecaprevir/pibrentasvir has 7,019. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known moderate interaction flagged in FDA labeling, attributed to taking these medications at the same time can cause a rise in liver enzymes. this is often a sign that the liver is under stress or being irritated.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
