1. What is Vitaminum C Teva and what is it used for
The active substance of the medicine is ascorbic acid, i.e., vitamin C, which belongs to water-soluble vitamins. It participates in the production of collagen and intercellular substance and is therefore necessary for the proper development of cartilage, bones, teeth, and also in wound healing. It also plays a very important role in the conversion of folic acid to folinic acid, facilitates the absorption of iron from the gastrointestinal tract, and participates in the production of hemoglobin and the maturation of erythrocytes (red blood cells).
The indication for the use of the medicine is:
- treatment of scurvy and other deficiency states requiring vitamin C supplementation. The medicine in the form of a parenteral solution is administered in severe cases or when oral administration is difficult.
2. Important information before using Vitaminum C Teva
When not to use Vitaminum C Teva:
- if the patient is allergic to vitamin C or any of the other ingredients of this medicine (listed in section 6);
- in kidney stones (oxalate).
Warnings and precautions
Particular caution should be exercised when using Vitaminum C Tevain the following cases:
- excessive amounts of oxalic acid or oxalates in the urine,
- tendency to form mineral deposits in the urinary system,
- hemochromatosis (a congenital metabolic disorder characterized by the deposition of iron in tissues),
- diabetes,
- thalassemia (a red blood cell disorder),
- sideroblastic anemia,
- glucose-6-phosphate dehydrogenase deficiency, as high doses of vitamin C may then cause red blood cell breakdown.
In patients taking high doses, tolerance to ascorbic acid may develop.
Vitamin C used in high doses (from 1 g per day) may falsify the results of some laboratory tests performed using oxidation-reduction methods (e.g., glucose concentration in urine, ethinyl estradiol concentration in serum, lactate dehydrogenase activity, liver transaminases in serum, occult blood test in stool, bilirubin concentration, urine pH, uric acid and oxalate content in urine, iron and ferritin concentration in serum).
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or plans to have a child, she should consult a doctor before using this medicine.
Pregnancy
High doses of vitamin C are not recommended during pregnancy, as their effect on the fetus is unknown.
During pregnancy, vitamin C should not be used in doses higher than the recommended daily intake (80-100 mg per day).
Breastfeeding
The medicine passes into breast milk, but there is no evidence of its harmful effect on breastfed infants.
During breastfeeding, vitamin C should not be used in doses higher than the recommended daily intake (80-100 mg per day).
Driving and using machines
The medicine is unlikely to affect the ability to drive and use machines.
Vitaminum C Teva and other medicines
The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
Substances that reduce tissue saturation with ascorbic acid include: acetylsalicylic acid, nicotine in cigarettes, alcohol, some appetite suppressants, iron, phenytoin, some anticonvulsants, estrogen - a component of oral contraceptives, and tetracycline.
Vitamin C used in high doses acidifies the urine, which reduces the excretion of acidic drugs and increases the excretion of basic drugs, thereby weakening their effect.
High doses of vitamin C may weaken the effect of oral anticoagulants.
When administered simultaneously with ascorbic acid, the concentration of flufenazine (a medicine used, among others, in schizophrenia) in serum may decrease.
Ascorbic acid administered as an auxiliary agent with deferoxamine in patients who have taken an overdose of iron (to improve its excretion) may increase its toxic effect, especially on the heart muscle, especially in the early stages of treatment, when the amount of iron in tissues is excessive. Therefore, such a combination should not be used in patients with impaired heart function, while in patients with normal heart function, the doctor will use vitamin C no earlier than one month after starting deferoxamine treatment.
In patients with impaired renal function using antacids containing aluminum and oral citrates, a life-threatening encephalopathy may develop, caused by a significant increase in aluminum concentrations in the blood. There are suspicions that vitamin C may interact similarly.
Oral contraceptives reduce the concentration of ascorbic acid in serum. Simultaneous use of these agents with vitamin C may result in increased estradiol concentration in serum.
Incompatibilities with other medicines
Vitamin C is incompatible with iron salts, oxidizing agents, and heavy metal salts, especially copper.
Incompatibilities of the vitamin C solution have been reported with: aminophylline, bleomycin sulfate, cefazolin (sodium salt), cefapirin, chlordiazepoxide, conjugated estrogens, dextran, doxapram (hydrochloride), erythromycin lactobionate, methicillin (sodium salt), nafcillin (sodium salt), nitrofurantoin (sodium salt), sulfafurazole diethanolamine, penicillin G (potassium salt), phytomenadione, sodium bicarbonate, warfarin.
Occasionally, depending on the pH and concentration, incompatibility with sodium succinate chloramphenicol may occur.

High doses of vitamin C may cause stomach and intestinal disorders, including diarrhea, vomiting, heartburn, skin redness, headache, and insomnia. High doses may also cause hyperoxaluria (increased excretion of oxalic acid in the urine) and the formation of oxalate kidney stones, if the urine becomes acidified. Daily doses of 600 mg and higher may have a diuretic effect.
Too rapid intravenous administration may cause dizziness and a feeling of weakness.
After long-term use of high doses, tolerance to ascorbic acid may develop, and when the dose is reduced, deficiency symptoms may occur.
