What is Drisdol

ErgocalciferolThe Generic name of this drug
Treatment SummaryErgocalciferol is a synthetic form of Vitamin D that is created by plants when exposed to UVB light. It was first discovered in 1931 and was used to treat Vitamin D deficiencies, which can cause rickets. Ergocalciferol is different from other forms of Vitamin D in that it has a double bond between C22 and C23 and a methyl group at C24. This affects how it binds to proteins, how quickly it is broken down, and how fast it is cleared from the body. The first product containing ergocalciferol was approved by the FDA in 1941.

Effectiveness

How Drisdol Affects PatientsErgocalciferol, also known as vitamin D2, helps the body absorb calcium and phosphorus, which are important for bone health. It also supports other processes in the body, such as cell growth and fetus development. However, ergocalciferol is not as strong as its counterpart, cholecalciferol (vitamin D3), in terms of absorbing minerals. Studies have found that taking ergocalciferol can help improve bone and mineral metabolism, glucose levels, albumin levels, and inflammation in people with end-stage kidney disease.
How Drisdol works in the bodyErgocalciferol is changed into its active form when it enters the body. This form then binds to its target, the vitamin D receptor. This activates the vitamin D endocrine system, and makes changes to certain genes in the DNA, called vitamin D response elements. The vitamin D receptor is a type of protein that helps control these elements and is part of the steroid hormone family. Ergocalciferol also helps with calcium absorption in the intestines.

Drisdol for Vitamin D Deficiency
This medication really helped with my seasonal depression. I noticed a difference within weeks of starting it, and friends and family members commented on the change in my mood. Once I finished the prescribed dosage, however, my depression returned. I'm making an appointment with my doctor to discuss going back on the medication until spring.

I took this medication for 8 months as directed by my doctor. I started at a low dose and worked my way up over the course of several weeks/months. I had a good experience with it and would recommend it to anyone who needs to bring their number up.

Drisdol for Prevention of Vitamin D Deficiency
Within the first week of treatment, I saw a remarkable difference in the pain I was experiencing from spondylitis. Additionally, my feet - which have always been dry and cracked - became softer. I'm very pleased with these results and plan to continue this medication long-term.

Drisdol for Low Amount of Calcium in the Blood
I've been on Drisdol 50000U once weekly for over six months now. I've had bone and joint pain in both legs but attributed it to my arthritis. Now after reading all the comments, I wonder if some of the pain has been caused by this supplementation. Interesting.

Drisdol for Vitamin D Deficiency
At first, the prescription said to take it daily. However, I started having spasms in my ribs that made it impossible to soothe them. Now I only take the Rx once a month, but still experience the spasms for about a week or two afterwards.

I am currently on week six of a twenty-week treatment of Vit D2, which I take once weekly. Recently, I have been experiencing aches and bone pain from my waist down, particularly in both knees. If anyone else is having similar issues, please let me know. I am using a heating pad for the time being but will be contacting my doctor in the morning.

I'm giving this treatment a try with my daughter who has hyperthyroidism. So far, she's only complained of thirstiness. If anyone has experience using this medication on children, I'd love to hear about it.

Drisdol for Vitamin D Deficiency (High Dose Therapy)
I was prescribed 50,000 iu of this medication to take once a week. The first time I took it, I had such bad anxiety for over a week until it got out of my system. I'm not taking it again; I may try a lower dose from the drugstore daily instead. It was a horrific experience!

After taking this for only four weeks (I was prescribed it for twelve), I started seeing a lot of negative side effects. These included fatigue, back pain, decreased appetite, stomach pain, and joint pain. Needless to say, I won't be using this medication any longer.
