special instructions

Amiviren is not used concomitantly with zidovudine for anemia (hemoglobin level less than 4.65 mmol / l) or neutropenia (neutrophil count less than 750 / μl).

If side effects from the digestive system appear (nausea, vomiting, abdominal pain) or an increase in the plasma level of pancreatic enzymes, the drug should be discontinued and not used until the diagnosis of pancreatitis is excluded.

Amiviren does not prevent the possibility of HIV infection through blood or sexual contact.

During treatment, a secondary infection may develop.

There is no experience with the drug in children under 3 months of age. In case of impaired renal function in childhood, the dosage regimen is adjusted in the same proportions as in adult patients.

Drug interactions

When taken together, lamivudine increases the duration of the therapeutic effect of zidovudine by 13% and increases its maximum concentration in blood plasma by 28%.

With the simultaneous use of Amiviren with zidovudine and other antiviral drugs that are used in the treatment of HIV infections, synergism is noted.

Sulfonamides, didanosine, and zalcitabine increase the risk of developing pancreatitis.

With the simultaneous appointment with isoniazid, dapsone, zalcitabine, didanosine or stavudine, the likelihood of peripheral neuropathy increases.

Trimethoprim increases the plasma concentration of lamivudine.
