What is Ergocalciferol

ErgocalciferolThe Generic name of this drug

Treatment SummaryErgocalciferol is a form of vitamin D analog. It is produced in plants when exposed to UVB light, and was discovered in 1931. Ergocalciferol is different from other forms of vitamin D because it has a double bond between two carbon atoms and a methyl group in a specific place. This makes it easier for the body to clear the vitamin D, and it also affects how the body breaks down the vitamin D. Ergocalciferol was approved for use by the FDA in 1941.

Effectiveness

How Ergocalciferol Affects PatientsErgocalciferol is a form of vitamin D that helps the body absorb calcium and phosphorus from food, as well as aiding in fetal development, immune function, and cell growth and differentiation. Compared to cholecalciferol, another form of vitamin D, ergocalciferol has a weaker effect. People with end-stage kidney disease have been shown to benefit from taking ergocalciferol, as it helps improve their bone and mineral metabolism, blood sugar levels, and inflammation.

How Ergocalciferol works in the bodyErgocalciferol is the active form of vitamin D. It needs to be changed in the body to work properly, and transported to certain organs so it can bind to its target, the vitamin D receptor. This binding has two effects: it changes how certain genes act, and it stimulates calcium transport in the intestines.

Ergocalciferol Toxicity & Overdose RiskAn overdose of ergocalciferol can cause hypervitaminosis, leading to high calcium levels, weakened kidney function, calcification of the tissues, slower growth, and increased bone mineralization. To treat an overdose, vitamin D should be stopped and a calcium-rich diet should be consumed along with plenty of fluids. Loop diuretics may be used to increase calcium excretion, while dialysis and other treatments may be recommended as well. There have not yet been any long-term studies on the cancer-causing or gene-altering effects of ergocalciferol or its effects on fertility.

Ergocalciferol for Vitamin D Deficiency (High Dose Therapy)

I've been taking Vitamin D2 for a couple months now and my levels have increased noticeably. I did start experiencing some low back pain, but I'm not sure if that's related or not.

Ergocalciferol for Osteoporosis

Note that D2 and D3 are NOT the same and have different uses. High levels of D2 (50,000) are tolerated and are used to increase calcium intake by bones. D3, often used for psoriasis should be a lower dose. D3 also produced by sunlight, approx. 10,000 iu with 10min of half body sun exposure according to Dr. H., a physiologist

I'm wondering why doctors prescribe D2 when D3 is more easily absorbed and actually effective. You can buy it anywhere too, which is great. I'll be trying out the supplements and will report back on how they work.

Ergocalciferol for Vitamin D Deficiency

I started taking this vitamin D2 supplement after noticing my nails were yellow. I was worried about potential liver or kidney damage, but it turns out I was just deficient in Vitamin D2! I'm on a 84 day course of treatment where I take one pill per week and so far (3/17/2022) the results have been good.

Ergocalciferol for Prevention of Vitamin D Deficiency

I had no idea that this drug would cause such severe back pain and muscle spasms. I was forced to stay in bed for five days as a result. Do not make the same mistake I did-- research Vitamin D deficiency treatments before starting anything.

Ergocalciferol for Vitamin D Deficiency

My doctor ordered a blood test which showed that I had severely low levels of Vitamin D. She prescribed 50,000 units to be taken twice a week for two months. I just took my second dose and experienced nausea and severe muscle pain. I was also diagnosed with the flu, so it's possible that the pill wasn't the cause of these symptoms. I'm going to try it again and see what happens.
