Therapeutic doses for adults are 50-100 mg 3-5 times a day; therapeutic doses for children are prescribed by a doctor.

Application during pregnancy and lactation During pregnancy and lactation, they are used only if the intended benefit to the mother outweighs the risk to the fetus and child. Theoretically, there is a danger to the child when the mother uses high doses of ascorbic acid. The minimum daily requirement for ascorbic acid in the II-III trimesters of pregnancy is about 60 mg. The minimum daily requirement during breastfeeding is 80 mg. A mother’s diet containing an adequate amount of ascorbic acid is sufficient to prevent vitamin C deficiency in an infant (it is recommended that the nursing mother not exceed the maximum daily requirement for ascorbic acid). Precautions Be careful when prescribing ascorbic acid to patients with increased blood clotting, hemochromatosis, sideroblastic anemia, sickle cell anemia, thalassemia, hyperoxaluria, nephrolithiasis, polycythemia, leukemia, progressive malignant diseases. In patients with high iron content in the body, ascorbic acid should be used in minimal doses. When taking large doses and long-term use of the drug, kidney function and blood pressure levels, as well as pancreatic function, should be monitored. Simultaneous intake of ascorbic acid and deferoxamine increases the excretion of iron. In patients with idiopathic hemochromatosis and thalassemia treated with deferoxamine, cases of cardiomyopathy and congestive heart failure have been recorded after taking ascorbic acid. In these situations, ascorbic acid should be administered with caution, monitoring of cardiac function is necessary. Ascorbic acid, as a reducing agent, can distort the results of various laboratory tests (blood glucose, bilirubin, activity of “liver” transaminases and lactate dehydrogenase). The drug is not recommended to be used simultaneously with other drugs containing ascorbic acid. Intensive consumption of chewable tablets can cause damage to tooth enamel. The absorption of ascorbic acid can be impaired in intestinal dyskinesias, enteritis and achilia. Concomitant use of vitamin C with antacids containing aluminum may increase the excretion of aluminum in the urine. Simultaneous use of antacids and ascorbic acid for a long period can lead to an increase in renal clearance and deficiency of ascorbic acid upon abrupt withdrawal of the drug. Large doses of ascorbic acid are associated with the formation of calcium oxalate stones in the kidneys. The use of ascorbic acid in therapeutic doses can distort the results of tests to determine glucosuria, uric acid concentration and creatinine. Children. The drug is used in children from 3 years of age. Interaction with other drugs Ascorbic acid increases the concentration of benzylpenicillin and tetracyclines in the blood. Improves intestinal absorption of Fe preparations (converts ferric iron to ferrous); May increase iron excretion when used concomitantly with deferoxamine. Reduces the effectiveness of heparin and indirect anticoagulants. Acetylsalicylic acid, oral contraceptives, fresh juices and alkaline drinks reduce the absorption and absorption of ascorbic acid. With simultaneous use with acetylsalicylic acid, the excretion of ascorbic acid in the urine increases and the excretion of acetylsalicylic acid decreases. Increases the risk of developing crystalluria in the treatment of salicylates and short-acting sulfonamides, slows down the excretion of acids by the kidneys, increases the excretion of drugs that have an alkaline reaction (including alkaloids), reduces the concentration of oral contraceptives in the blood. Increases the overall clearance of ethanol, which in turn reduces the concentration of ascorbic acid in the body. With the simultaneous use of ascorbic acid and isoprenaline, the chronotropic effect of isoprenaline decreases. Barbiturates and primidone increase the excretion of ascorbic acid in the urine. Reduces the therapeutic effect of antipsychotic drugs (neuroleptics) – phenothiazine derivatives, tubular reabsorption of amphetamine and tricyclic antidepressants. The combined intake of vitamin C and deferoxamine increases the tissue toxicity of iron, especially in the heart muscle, which can lead to decompensation of the circulatory system. Vitamin C can be taken 2 hours after deferoxamine injection. Preparations of the quinoline series (fluoroquinolones, etc.), calcium chloride, salicylates, glucocorticosteroids with prolonged use deplete the reserves of ascorbic acid. Contraindications Hypersensitivity to ascorbic acid and other components of the drug.
