Lipoic acid can be taken on a long-term basis as prescribed by your doctor. Lipoic acid is mainly used for the treatment of diabetic peripheral neuropathy, and its mechanism of action is mainly to eliminate free radicals that cause accelerated aging and pathogenicity. Lipoic acid is a B vitamin, which plays the role of coenzymes in the multi-enzyme system. Peripheral neuropathy is a chronic disease, so long-term treatment with lipoic acid is usually required. Lipoic acid is rapidly absorbed when taken orally, with a half-life of 25 minutes, and is mainly excreted through the kidneys. However, it is not recommended for children, the elderly, pregnant women, and nursing mothers. Lipoic acid should be taken separately from food, as food can interfere with its absorption. Alcohol consumption can affect the efficacy of treatment, and abstinence from alcohol is required during treatment. It is contraindicated for those who are allergic to the product. Adverse reactions to lipoic acid include allergic reactions as well as hypoglycemia, both of which are rare and require immediate discontinuation of the medication as well as notification of the doctor and appropriate treatment. Lipoic acid should be used under the supervision of a doctor, and the specific treatment plan should be formulated by the doctor according to the condition.
