There is no single best medicine for liver disease because the right treatment depends entirely on which type of liver disease you have. Hepatitis B, hepatitis C, fatty liver disease, autoimmune hepatitis, and cirrhosis each require different medications targeting different problems. What works remarkably well for one condition can be useless or even harmful for another.
The good news is that treatments have improved dramatically in recent years. Hepatitis C is now curable in over 95% of cases, and in 2024 the FDA approved the first medication specifically for fatty liver disease with scarring. Here’s what’s currently used for each major type of liver disease.
Hepatitis C: Cure Rates Above 95%
Hepatitis C treatment is one of modern medicine’s biggest success stories. Direct-acting antiviral medications cure the infection in more than 95% of people, regardless of the viral strain, race, HIV status, or how much liver scarring is already present. Most treatment courses last just 12 weeks and are taken as daily pills.
In a large analysis of over 103,000 people with chronic hepatitis C treated through the Veterans Affairs system, 96.8% achieved a sustained virologic response, meaning the virus was undetectable and considered cured. Even people with compensated cirrhosis (significant scarring but the liver still functions) typically clear the virus at rates above 95% with a standard 12-week course. If you’ve been diagnosed with hepatitis C, getting treated early prevents further liver damage and substantially lowers your risk of death from liver-related causes.
Hepatitis B: Long-Term Antiviral Therapy
Unlike hepatitis C, chronic hepatitis B usually can’t be cured outright. Instead, treatment focuses on suppressing the virus to prevent liver damage from progressing. Three oral antivirals are recommended as first-line options: entecavir, tenofovir alafenamide, and tenofovir disoproxil fumarate. All three are taken once daily and are generally well tolerated for long-term use, which is important because many people with hepatitis B stay on treatment indefinitely.
An injectable option, peginterferon, is sometimes used for a fixed 48-week course. It works differently by stimulating the immune system rather than directly blocking the virus, and some patients prefer the idea of a defined treatment period. However, it comes with more side effects and isn’t suitable for everyone. Your doctor will choose based on factors like your viral load, degree of liver damage, and whether you have other health conditions.
Fatty Liver Disease (MASH/NASH)
For decades, the only advice for fatty liver disease was to lose weight, eat better, and exercise. That changed in March 2024 when the FDA approved resmetirom (brand name Rezdiffra), the first medication specifically for metabolic dysfunction-associated steatohepatitis, the more advanced form of fatty liver disease where inflammation and scarring are present.
Rezdiffra is approved for adults with moderate to advanced liver fibrosis (stages F2 to F3) who don’t yet have decompensated cirrhosis. It’s taken once daily, with the dose based on body weight: 80 mg for people under 100 kg and 100 mg for those at or above 100 kg. The medication works alongside diet and exercise, not as a replacement for them. It’s not approved for people whose fatty liver hasn’t yet progressed to significant scarring, so lifestyle changes remain the primary treatment for earlier stages.
Autoimmune Hepatitis
When the immune system attacks the liver, the standard treatment is corticosteroids to suppress that immune response. Prednisone has been the cornerstone of autoimmune hepatitis treatment for over four decades, typically started at moderate doses that are gradually tapered down. After the initial inflammation is controlled, most patients transition to a steroid-sparing medication called azathioprine, which allows them to reduce or stop steroids while keeping the immune system in check.
Before starting azathioprine, doctors test for an enzyme deficiency that would make the drug dangerous. In patients with decompensated cirrhosis (where the liver has lost significant function), azathioprine is avoided entirely. Treatment for autoimmune hepatitis is often long-term, and flares can occur if medications are stopped too quickly.
Primary Biliary Cholangitis
Primary biliary cholangitis (PBC) slowly destroys the bile ducts inside the liver. The first-line treatment is ursodeoxycholic acid, a bile acid that protects liver cells and improves bile flow. About 20% of patients see their liver blood tests return to normal after two years on the medication. However, up to 40% of PBC patients have an inadequate response.
For those who don’t respond well enough after at least a year, obeticholic acid (approved in 2016) can be added as a second-line treatment. In its pivotal trial, roughly 46-47% of patients met the primary treatment target after one year, compared to just 10% on placebo. For people who can’t tolerate ursodeoxycholic acid at all, obeticholic acid can be used on its own.
Managing Cirrhosis Complications
Cirrhosis itself can’t be reversed with medication, but several drugs manage its complications and slow progression. The specific medications depend on which complications develop.
Fluid buildup (ascites and edema) is treated with diuretics, commonly called water pills, which help your body shed excess fluid. High pressure in the veins feeding the liver, called portal hypertension, is managed with beta blockers that reduce the risk of dangerous bleeding from swollen veins in the esophagus or stomach.
One of the most concerning complications is hepatic encephalopathy, a buildup of toxins (primarily ammonia) that causes confusion, disorientation, and in severe cases, coma. The primary treatment is lactulose, a synthetic sugar that works in the gut to trap ammonia and flush it out through bowel movements. The dose is adjusted so you have two to four loose stools per day. Rifaximin, an antibiotic that stays mostly in the gut, is often added alongside lactulose to further reduce ammonia-producing bacteria. Zinc supplements may also help because zinc supports the body’s natural ammonia-processing cycle.
Acute Liver Failure
Acute liver failure is a medical emergency, and treatment depends on the cause. The most common cause in the United States is acetaminophen (Tylenol) overdose, and the primary treatment is N-acetylcysteine (NAC). NAC works best when given early, but it may also offer some liver protection in non-acetaminophen-related acute liver failure and other forms of drug-induced liver injury. When the cause is autoimmune hepatitis or hepatitis B, targeted treatments for those conditions are started urgently. In the most severe cases, a liver transplant becomes necessary.
Wilson’s Disease
Wilson’s disease is a rare genetic condition where copper accumulates in the liver and brain. Treatment uses chelating agents, medications that bind copper and help your body excrete it. The two chelating drugs used are penicillamine and trientine. Once excess copper has been removed, doctors often switch to zinc supplements as a maintenance treatment. Zinc works differently: it blocks the intestines from absorbing copper in the first place, keeping levels from building back up.
Medications to Avoid With Liver Disease
Knowing what not to take matters just as much as choosing the right treatment. If you have cirrhosis or significant liver damage, your body processes many drugs differently, and some common over-the-counter medications become risky.
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen should be avoided because they raise the risk of kidney failure and gastrointestinal bleeding in people with cirrhosis. Opioid painkillers, anti-anxiety medications, and sedatives require extreme caution because they can trigger hepatic encephalopathy. Proton pump inhibitors (heartburn medications like omeprazole) have been linked to higher infection rates in cirrhosis patients and should only be used when truly needed.
Acetaminophen, perhaps surprisingly, is considered the safer pain option for people with liver disease, but only at reduced doses of 2 to 3 grams per day or less and for short periods. Many people assume acetaminophen is the worst choice because of its reputation for liver toxicity at high doses, but at appropriate doses it’s actually preferred over NSAIDs in this population.
