Carbamazepine	Zinc citrate can cause a decrease in the absorption of Carbamazepine resulting in a reduced serum concentration and potentially a decrease in efficacy.
Ceftibuten	Zinc citrate can cause a decrease in the absorption of Ceftibuten resulting in a reduced serum concentration and potentially a decrease in efficacy.
Cephalexin	Zinc citrate can cause a decrease in the absorption of Cephalexin resulting in a reduced serum concentration and potentially a decrease in efficacy.
Cinoxacin	Zinc citrate can cause a decrease in the absorption of Cinoxacin resulting in a reduced serum concentration and potentially a decrease in efficacy.
Ciprofloxacin	Zinc citrate can cause a decrease in the absorption of Ciprofloxacin resulting in a reduced serum concentration and potentially a decrease in efficacy.

Food Interactions

• Avoid milk and dairy products. Separate the use of zinc from these products by at least 2 hours before administration. Separate for 2 hours after administration if these products also contain phosphorus.
• Do not take with bran and high fiber foods. For optimal absorption, take zinc citrate at least 2 hours before or after eating high-fiber foods.
• Take on an empty stomach. Take at least 1 hour before and 2 hours after eating for optimal absorption. Zinc can be taken with food to reduce gastrointestinal upset.
