What is Ornithine Aspartate?
Hepa-Merz is an over‑the‑counter oral supplement that provides the amino‑acid complex ornithine aspartate. Each dose delivers ornithine and aspartate to support the liver’s urea cycle and aid ammonia detoxification. Marketed in the European Union, the product is intended for adult use without a specified strength or dosage form, and it is classified as a hepatic‑support amino‑acid supplement and can be purchased in pharmacies or online.
What is Ornithine Aspartate used for?
Hepa-Merz is commonly used as an adjunct in conditions where liver function and ammonia handling are compromised.
- Management of hepatic encephalopathy in adults. - Support of liver function in chronic liver disease. - Adjunctive therapy during recovery from acute liver injury. - Nutritional support for patients with cirrhosis. - May be considered in metabolic disorders affecting the urea cycle. - Support for patients undergoing hepatic surgery or transplantation.
What are the side effects of Ornithine Aspartate?
The safety profile of Hepa-Merz reflects the typical tolerability of oral amino‑acid supplements, with most users experiencing mild, transient effects.
Common: - Mild gastrointestinal discomfort such as nausea or bloating. - Transient headache. - Slight increase in urine odor due to nitrogen excretion.
Serious: - Allergic skin reaction (rash, itching, swelling). - Signs of hepatic decompensation (jaundice, worsening encephalopathy). - Unexplained abdominal pain. - Severe hypersensitivity (anaphylaxis).
What precautions apply to Ornithine Aspartate?
When considering Hepa-Merz, certain precautionary measures are recommended to ensure safe use.

What does Ornithine Aspartate interact with?
Hepa-Merz may interact with other substances that affect ammonia metabolism or liver function.
Avoid: - Concurrent use with high‑dose ammonia‑lowering agents (e.g., sodium benzoate) without medical guidance. - Combination with other oral amino‑acid supplements exceeding recommended daily intake.
Use with caution: - Co‑administration with diuretics that may alter electrolyte balance. - Use alongside lactulose or rifaximin, as additive effects on ammonia levels may occur. - Potential interaction with medications metabolized by hepatic enzymes (e.g., certain antiepileptics). - Alcohol consumption may reduce the supplement’s effectiveness.
