Ergocalciferol is used to treat familial hypophosphatemia, resistant rickets (a disorder in which the bones become softer and weaker and do not respond to treatment), and hypoparathyroidism (a condition in which the body does not create enough parathyroid hormone) (rickets or osteomalacia caused by an inherited condition with a decreased ability to break down vitamin D in the body). Ergocalciferol belongs to a group of drugs known as vitamin D analogues. It functions by encouraging the body to absorb more calcium from meals or supplements.

Ergocalciferol is available as a pill to swallow. Typically, it is given once day. Ergocalciferol should be taken every day at roughly the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Ergocalciferol should be taken as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not chew or crush the capsules; instead, swallow them whole.

Depending on how well ergocalciferol is tolerated by your body, your doctor may adjust your dose.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

Before taking ergocalciferol,

• If you have any allergies to any of the substances in ergocalciferol capsules, including tartrazine (a yellow dye found in some processed foods and medications), aspirin, or any other medications, let your doctor and pharmacist know right once. Get a list of the components from your pharmacist.
• Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Incorporate any of the following: Supplements for calcium, additional vitamin D supplements, fortified meals, or thiazide diuretics (often known as “water pills”) like chlorothiazide (Diuril), hydrochlorothiazide (included in many blood pressure drugs), indapamide, and metolazone are all examples of thiazide diuretics (Zaroxolyn). You and your carer should be aware that several over-the-counter drugs should not be taken with ergocalciferol. Before using any over-the-counter drugs while taking ergocalciferol, see your doctor. Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
• Inform your physician if you have malabsorption syndrome, abnormal vitamin D sensitivity, excessive calcium and vitamin D levels in your blood, or any of these conditions (problems absorbing food). Most likely, your doctor will advise against using ergocalciferol.
• If you have kidney or liver problems now or in the past, let your doctor know.
• Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. Call your doctor if you become pregnant while taking ergocalciferol.

Ergocalciferol only functions if you additionally consume the recommended quantity of calcium from food sources. Ergocalciferol use may result in negative side effects if you consume too much calcium from meals. Ergocalciferol won’t help you control your condition if you don’t consume enough calcium-rich meals. Your physician will advise you on the best calcium-rich foods to eat as well as the recommended daily serving sizes. Inform your doctor if you have trouble consuming enough of these items. Your doctor may then suggest or prescribe a calcium supplement in that situation.

In addition, a low-phosphate diet may be advised by your physician while you are taking ergocalciferol. Pay close attention to these guidelines.

If you miss a dosage, take it as soon as you recall. If the next dose is soon due, skip the missed one and carry on with your regular dosing plan. To make up for a missing dose, do not take a second one.
