1.What is Vitamin D2?
Ergocalciferol is vitamin D2. Vitamin D helps your body absorb calcium. Ergocalciferol is used to treat hypoparathyroidism (decreased functioning of the parathyroid glands). Ergocalciferol is also used to treat rickets (softening of the bones caused by vitamin D deficiency) or low levels of phosphate in the blood (hypophosphatemia). Ergocalciferol may also be used for purposes not listed in this medication guide.
2.How to use Vitamin D2?
Take vitamin D by mouth as directed. Vitamin D is best absorbed when taken after a meal but may be taken with or without food. Alfacalcidol is usually taken with food. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist. If your doctor has prescribed this medication, take as directed by your doctor. Your dosage is based on your medical condition, amount of sun exposure, diet, age, and response to treatment. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If you are taking the chewable tablet or wafers, chew the medication thoroughly before swallowing. Do not swallow whole wafers. If you are taking the rapidly-dissolving tablets, dry your hands before handling the medication. Place each dose on the tongue, allow it to dissolve completely, and then swallow it with saliva or water. You do not need to take this medication with water. Certain medications (bile acid sequestrants such as cholestyramine/colestipol, mineral oil, orlistat) can decrease the absorption of vitamin D. Take your doses of these medications as far as possible from your doses of vitamin D (at least 2 hours apart, longer if possible). It may be easiest to take vitamin D at bedtime if you are also taking these other medications. Ask your doctor or pharmacist how long you should wait between doses and for help finding a dosing schedule that will work with all your medications. Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day if you are taking it once a day. If you are taking this medication only once a week, remember to take it on the same day each week. It may help to mark your calendar with a reminder. If your doctor has recommended that you follow a special diet (such as a diet high in calcium), it is very important to follow the diet to get the most benefit from this medication and to prevent serious side effects. Do not take other supplements/vitamins unless ordered by your doctor. If you think you may have a serious medical problem, get medical help right away.
3.How Vitamin D2 (ergocalciferol) works？
Vitamin D2 (ergocalciferol) is a form of vitamin D that's available as a dietary supplement. Vitamin D allows your body to absorb more calcium and phosphate, which is important to keep your bones healthy and strong. If you have problems with your parathyroid gland, your body doesn't make vitamin D very well on its own. Vitamin D2 (ergocalciferol) replaces the vitamin D your parathyroid gland isn't making.
4.What are Pharmacist tips for Vitamin D2 (ergocalciferol)?
You can take vitamin D2 (ergocalciferol) with or without food at any time of the day. Taking it with a meal or right after you wake up can make it easier for you to remember. Try to take vitamin D2 (ergocalciferol) at the same time every day so the medication levels stay consistent in your body. Don't take more vitamin D2 (ergocalciferol) than instructed by your provider, since this can lead to unwanted side effects like nausea and vomiting. Contact your provider if you notice an unexplainable loss of appetite, weight loss, weakness, general aches, or stiffness. These can be signs that your dose is too high. Continue to take vitamin D2 (ergocalciferol) as long as your provider tells you to do so. The length of time you'll use it is different for everyone, since it depends on your condition and the results of your blood tests. Because vitamin D2 (ergocalciferol) can be used for genetic or ongoing conditions, it's possible you might need to take this medication long term or even for the rest of your life. Be sure to get any ordered blood tests done on time, because your lab results can affect your dose. Don't start taking other forms of vitamin D without first discussing it with your provider to avoid taking too much. This can include multivitamins and foods (like milk or orange juice) that have been fortified with vitamin D. Make sure your providers have a list of all your medications and supplements that you take on a regular basis, including the ones you purchase over the counter.
