Inosine tablets are an over-the-counter drug often used clinically as an adjunct to acute and chronic hepatitis as well as cirrhosis. Patients with liver disease can significantly improve liver function and promote the recovery of damaged liver cell function after taking them. Inosine tablets can also participate in cellular energy metabolism and protein metabolism, and can also be used to treat thrombocytopenia, leukopenia, heart disease, central retinitis, optic nerve atrophy and other disorders. Inosine tablets have few adverse effects. A few patients may experience stomach upset, indigestion, mild diarrhea and bloating during application, but they are usually tolerated without discontinuation of the drug. The use of this drug is strictly contraindicated in a very small number of patients who are allergic to it. There is a lack of clear clinical data on other adverse reactions and contraindications to this drug. This drug must be used under the supervision of a physician and should not be taken without authorization. The dosage should not be increased or decreased without authorization, which may affect the therapeutic effect of the drug or lead to various uncomfortable symptoms.
