Vitamin D (ergocalciferol) Coupons & Savings Card – Discount Prices from $6.35

Ergocalciferol, commonly known as vitamin D₂, is used to treat conditions like hypoparathyroidism, rickets, and certain types of hypophosphatemia. While it can be beneficial, it's important to be aware of specific risks associated with its use.

Individuals with high levels of calcium in their blood (hypercalcemia), excessive vitamin D levels (hypervitaminosis D), or conditions that impair nutrient absorption (malabsorption syndromes) should avoid ergocalciferol, as it may exacerbate these issues. Additionally, those with a known hypersensitivity to vitamin D should not use this supplement.

In infants with idiopathic hypercalcemia, a condition where the cause of high calcium levels is unknown, vitamin D intake must be strictly limited to prevent further complications.

For patients with hyperphosphatemia, often seen in renal osteodystrophy, maintaining normal serum phosphorus levels is crucial. This may involve dietary phosphate restrictions or the use of aluminum-based phosphate binders to prevent unwanted calcium deposits in tissues.

Adequate dietary calcium is essential for ergocalciferol to be effective. However, excessive calcium intake can lead to complications, so it's important to balance calcium consumption appropriately.

Certain formulations of ergocalciferol contain FD&C Yellow No. 5 (tartrazine), a dye that can cause allergic reactions, including bronchial asthma, in susceptible individuals. This sensitivity is more common in people who are also allergic to aspirin.

During pregnancy, excessive vitamin D intake has been linked to fetal abnormalities. Therefore, it's advisable to avoid doses exceeding the recommended dietary allowance unless a healthcare provider determines that the benefits outweigh the risks.

Nursing mothers should exercise caution, as high doses of vitamin D can pass into breast milk and may lead to elevated calcium levels in the nursing infant. Monitoring the infant's serum calcium concentration is recommended in such cases.

Elderly patients may experience reduced absorption of vitamin D. Therefore, dosing should be approached cautiously, typically starting at the lower end of the dosing range, to account for potential age-related decreases in liver, kidney, or heart function.

It's important to protect ergocalciferol from light to maintain its effectiveness.

Always consult with a healthcare provider before starting ergocalciferol to ensure it's appropriate for your specific health needs and to determine the correct dosage.

Ergocalciferol, also known as vitamin D2, is commonly prescribed to address vitamin D deficiencies and related conditions. While it is generally safe when taken as directed, some individuals may experience side effects. Common Side Effects:

• Gastrointestinal Issues: Some people may experience nausea, vomiting, constipation, or diarrhea. These symptoms are typically mild and may diminish as the body adjusts to the supplement.
• Fatigue and Weakness: Feelings of tiredness or muscle weakness can occur. If these symptoms persist or worsen, it's advisable to consult a healthcare provider. Serious Side Effects:
• Hypercalcemia (High Calcium Levels): Excessive intake of ergocalciferol can lead to elevated calcium levels in the blood. Symptoms may include frequent urination, increased thirst, loss of appetite, nausea, vomiting, constipation, and confusion. In severe cases, it can result in kidney stones or heart rhythm abnormalities. Regular monitoring of blood calcium levels is recommended during treatment.
• Allergic Reactions: Although rare, some individuals may experience allergic reactions characterized by rash, itching, swelling of the face, tongue, or throat, severe dizziness, or difficulty breathing. Immediate medical attention is necessary if any of these symptoms occur. Precautions: Certain individuals should exercise caution when taking ergocalciferol:
• Pre-existing Conditions: Those with hyperparathyroidism, sarcoidosis, or kidney disease may have an increased risk of complications and should use this supplement only under strict medical supervision.
• Medication Interactions: Ergocalciferol can interact with various medications, including steroids, weight loss drugs, and cholesterol-lowering agents. These interactions can affect the effectiveness of either the supplement or the other medications and may increase the risk of adverse effects. It's important to inform your healthcare provider about all medications and supplements you are currently taking. To minimize the risk of side effects, adhere to the prescribed dosage and attend regular follow-up appointments with your healthcare provider. They can monitor your blood levels and overall health to ensure the supplement is benefiting you without causing harm.

When taking ergocalciferol (vitamin D2), it's important to be aware of potential interactions with other medications and substances that can affect its effectiveness or lead to adverse effects. Here are some key interactions to consider:

Medications That May Decrease Ergocalciferol Absorption:

• Bile Acid Sequestrants: Drugs like Cholestyramine and Colestipol can reduce the absorption of vitamin D. To minimize this interaction, it's advisable to take vitamin D at least two hours before or after these medications.

• Mineral Oil: Regular use of mineral oil as a laxative can interfere with the absorption of fat-soluble vitamins, including vitamin D. To avoid this, separate the intake of mineral oil and vitamin D by several hours.

• Orlistat: This weight-loss medication can decrease the absorption of vitamin D. It's recommended to take vitamin D at least two hours before or after orlistat.

Medications That May Increase the Risk of Hypercalcemia:

• Thiazide Diuretics: Drugs such as Hydrochlorothiazide can increase calcium levels in the blood. When taken with vitamin D, there's a heightened risk of hypercalcemia. Monitoring calcium levels is essential if these medications are used together.

• Calcium Supplements: Concurrent use of high doses of calcium supplements with vitamin D can elevate calcium levels, potentially leading to hypercalcemia. It's important to follow dosing recommendations and monitor calcium levels.

Medications That May Alter Ergocalciferol Metabolism:

• Anticonvulsants: Medications like Phenobarbital and Phenytoin can increase the metabolism of vitamin D, potentially reducing its effectiveness. Adjustments to vitamin D dosage may be necessary when taking these drugs.

• Corticosteroids: Long-term use of corticosteroids can interfere with vitamin D metabolism, leading to decreased calcium absorption. Monitoring and possible supplementation may be required.

Other Considerations:

• Cardiac Glycosides: Vitamin D can enhance the effects of cardiac glycosides (e.g., Digoxin), increasing the risk of arrhythmias. Close monitoring is advised when these are used together.

• Aluminum-Containing Antacids: Combining these with vitamin D can lead to increased aluminum absorption, which may be harmful, especially in individuals with kidney issues. It's best to avoid this combination.

Always inform your healthcare provider about all medications and supplements you're taking to ensure safe and effective use of vitamin D.
