Pharmacological Management

Medicines can cure some liver diseases, control others for life and prevent dangerous complications in advanced disease. The liver also breaks down most drugs, so a diseased liver can change how a medicine works, how long it stays in the body and how likely it is to cause side effects. Prescribing therefore needs specialist knowledge.

Medicines That Treat the Cause

• Hepatitis C: Direct-acting antivirals, usually taken for 8 to 12 weeks, cure the majority of patients.
• Hepatitis B: Oral antivirals such as tenofovir or entecavir suppress the virus. Treatment is often long-term and must never be stopped without medical advice, since stopping can trigger a dangerous flare.
• Autoimmune hepatitis: Corticosteroids followed by azathioprine, and other immunosuppressants when needed.
• Primary biliary cholangitis: Ursodeoxycholic acid as first-line therapy, with second-line agents for poor responders.
• Wilson disease: Copper chelators such as D-penicillamine or trientine, and zinc to block copper absorption.
• Hemochromatosis and iron overload: Phlebotomy is the mainstay, and iron chelators are used when phlebotomy is not possible.
• Fatty liver: Medicines for diabetes, cholesterol and blood pressure. In selected patients with MASH and significant fibrosis, newer liver-directed drugs may be considered by a specialist, depending on availability.
• Alcohol-related liver disease: Medicines that help maintain abstinence, vitamin supplementation, and, in selected patients with severe alcoholic hepatitis, corticosteroids.

Medicines That Prevent or Treat Complications

• Ascites: Diuretics such as spironolactone and furosemide, sometimes with albumin infusions.
• Variceal bleeding prevention: Non-selective beta-blockers such as propranolol or carvedilol.
• Hepatic encephalopathy: Lactulose to clear the gut, with rifaximin added to prevent recurrence.
• Spontaneous bacterial peritonitis: Antibiotics for treatment and, in selected patients, for prevention.
• Hepatorenal syndrome: Albumin with vasoconstrictors such as terlipressin.
• Bleeding in the acute setting: Vasoactive drugs and antibiotics before endoscopy.
• Itching in cholestasis: Cholestyramine, rifampicin, naltrexone or sertraline.
• Muscle cramps: Correction of electrolytes, and sometimes specific medicines.
• Low sodium, low potassium and other imbalances: Corrected under supervision.

Vitamins and Supplements

Some patients need calcium, vitamin D, zinc or fat-soluble vitamins (A, D, E, K) when levels are low or absorption is poor. These should be prescribed based on tests, since high doses of some vitamins, such as vitamin A, can harm the liver.

Medicines to Avoid or Use With Care

• NSAIDs (diclofenac, ibuprofen, aspirin in high doses): Can cause kidney injury and bleeding in cirrhosis
• Sedatives, sleeping pills and opioids: May trigger encephalopathy
• Paracetamol: Safe at low doses, generally up to about 2 g per day in cirrhosis, but dangerous in overdose
• Certain antibiotics, anti-tuberculosis drugs and anti-epileptics: Need monitoring
• Herbal and traditional remedies: May cause serious liver injury
• Anticoagulants: Require specialist guidance

Always tell doctors and pharmacists that you have liver disease before starting any new medicine.

Monitoring Treatment

Blood tests, viral load tests, drug levels, kidney function and imaging help doctors judge whether treatment is working and whether side effects are developing. For example, patients taking azathioprine need regular blood counts, and patients on diuretics need electrolyte and kidney checks.

Adherence: The Key to Success

• Take medicines exactly as prescribed, at the same time each day
• Never stop antivirals, immunosuppressants or chelators on your own
• Use pill boxes, phone reminders or family support
• Refill prescriptions before they run out
• Report side effects instead of stopping medicines
• Keep a written list of all medicines and doses

Safety Tips

• Buy medicines from licensed pharmacies and check expiry dates
• Avoid duplicating drugs that contain the same ingredient, such as multiple paracetamol products
• Store medicines safely, away from children
• Ask your doctor about interactions with food, alcohol and other drugs
• Discuss pregnancy plans before starting or continuing certain medicines

Cost and Access

Many liver medicines, including generic antivirals, are available at affordable prices in India, and some are supplied through government programmes. Ask your doctor about generic options and available schemes so that treatment is not interrupted for financial reasons.
