Prevention and treatment of vitamin D poisoning

I believe that everyone may have encountered cases of vitamin D poisoning in their lives. We must be wondering, how to prevent and treat vitamin D poisoning? Vitamin D is an important trace element necessary for the human body, and everyone in today's society attaches great importance to its absorption and supplementation. Let’s take a look at the prevention and supplementation of vitamin D poisoning.

treat:

1. Immediately stop taking VitD preparations and calcium supplements after vitamin D poisoning is confirmed, avoid sunlight exposure, and give a low-calcium diet.

2. Control infection and correct dehydration and acidosis. In general cases, it takes a long time for the above treatment to gradually recover. It takes about 2 to 3 months for blood calcium to return to normal, and kidney function may take up to 18 months to recover.

3. Specific treatment: Adrenal cortex hormone can inhibit the intestinal absorption of calcium and has an antagonistic effect on VitD. Take oral prednisone 1-2 mg/kg/d, and the blood calcium will return to normal after 1-2 weeks. Generally, the blood calcium will no longer rise after 2-3 weeks of continuous use. In severe cases, the medication time can be appropriately extended based on blood calcium and X-ray images. Oral sulfuric acid can reduce calcium absorption. Older children can use 1 to 2 grams.

prevention:

1. Understand the dosage of VitD for prevention or treatment. The preventive dosage should not exceed 400 IU per day. Parents should be informed of the dangers of excessive VitD and the medication should be used according to the doctor's orders.

2. Before emergency treatment is needed, the child should be asked in detail about the dose of VitD he or she has used in the past. Most poisoning cases occur on the basis of long-term and large-scale oral intake of cod liver oil. Symptoms of poisoning are more likely to occur after D2 or D3 injection. Therefore, it is important to understand the indications before injecting large doses.

3. If the therapeutic effect of general VitD dosage is unsatisfactory, blood calcium, phosphorus and alkaline phosphatase should be checked before deciding whether to use intensive therapy.

4. In the prevention and treatment of general nutritional rickets, try to avoid large doses of vitamin D. When large doses of vitamin D must be used for treatment, closely observe the clinical symptoms, measure blood calcium monthly for signs of poisoning, and measure once every half month if necessary.

5. Practice has shown that 20 IU of VD has the same effect as 400,000 IU. When a large dose of VitD is required for emergency treatment, it is best not to exceed 20 IU, and a second injection is generally not required. For children with normal liver, kidney and gastrointestinal function, oral administration of VitD has the same effect as intramuscular injection. Oral administration is safe and intramuscular injection is not necessary.

From above we know some things about the prevention and treatment of vitamin D poisoning. We must know that everything is about having enough rather than too much. Too much vitamin D will not only not be absorbed by the human body, but will also cause blood calcium to deposit in bones and other organ tissues, affecting their functions. I hope this helps you all.
