Vigor-ACE Special Precautions

Oral vitamin A preparations should not be used for treating vitamin A deficiency in persons with malabsorption syndromes.
Chronic consumption of vitamin A may cause liver damage.
Vitamin C should be used with caution in patients with renal failure (risk of oxalate stones), erythrocyte glucose-6-phosphate dehydrogenase (G6PD) deficiency (risk of hemolytic anemia), hemochromatosis, sickle cell anemia (risk of precipitating a crisis), thalassemia, or sideroblastic anemia.
High doses of vitamin E (i.e., doses greater than 100 IU) should be used with caution in patients on warfarin. Monitoring of international normalized ratio (INR) and adjusting of warfarin dose (if indicated) are recommended. Likewise, those with vitamin K deficiencies, such as patients with liver failure, should be cautious in taking high doses of vitamin E.
Vitamin E should be used with extreme caution in those with any lesions that have a tendency to bleed (e.g., bleeding peptic ulcers), those with a history of hemorrhagic stroke, and those with inherited bleeding disorders (e.g., hemophilia).
Zinc should be used with caution in patients with kidney disease.
Do not use more than the recommended dose. If the patient is taking other supplements, read the label, since those supplements may contain the same ingredients as this product. Patients under the care of a doctor or those receiving any other medication should consult a physician before taking this product.
Consult a doctor before using this product if the patient is: have a history of stroke or risk factors for stroke; have any coagulation (blood clotting) problem or is taking anticoagulants (e.g., warfarin).
If any adverse reactions occurs.
