ImmunPro Prime Drug Interactions

Ascorbic acid (Vitamin C): Antacids: Increased risk of aluminum toxicity has been noted with concomitant use; therefore, it is not recommended, especially in patients with renal insufficiency.
Aspirin: Concomitant intake may lead to increased urinary excretion of ascorbic acid and decreased excretion of aspirin.
Disulfiram: Prolonged administration of large doses (1 g daily) of vitamin C may interfere with the alcohol-disulfiram reaction.
Fluphenazine: Concomitant administration with vitamin C resulted in decreased fluphenazine plasma level.
Iron: Concomitant administration of more than 200 mg of vitamin C per 30 mg elemental iron increases absorption of iron from the gastrointestinal tract.
Paracetamol: Vitamin C increases the apparent half-life of paracetamol.
Zinc: Antibiotics: Zinc decreases the absorption of certain antibiotics such as quinolones (e.g., ciprofloxacin, levofloxacin, ofloxacin) and tetracyclines (e.g., doxycycline, tetracycline). This medicine contains zinc and must be given at least 2 hours after or 6 hours before antibiotics.
Bisphosphonates: Concomitant intake of zinc and a bisphosphonate (e.g., alendronate, etidronate, risedronate) may decrease the absorption of both zinc and the bisphosphonate.
Cholesterol medicines: Additive effects are possible with concomitant administration; use with caution.
Copper or iron: Zinc inhibits the absorption of copper and iron. Administer zinc and copper or iron as far apart as possible.
Penicillamine: Zinc may reduce the absorption of penicillamine.
Food: Concomitant intake of zinc and caffeine or tea may reduce zinc absorption. Foods containing high levels of phosphorus, calcium (dairy), phytates (e.g., bran, brown bread), or folic acid may also reduce its absorption.
Colecalciferol (Vitamin D3): Anticonvulsants, cimetidine and thiazides: Concomitant use may decrease the effect of vitamin D.
Bile acid sequestrants (e.g. cholestyramine and colestipol), mineral oil and orlistat: Concomitant use may reduce the absorption of vitamin D.
Tell the doctor if the patient is taking other medicines, including herbal medicines and food supplements.
