Drug Information
Nizatidine is a member of the H-2 blocker (histamine blocker) family of drugs that prevents the release of acid into the stomach. Nizatidine is used to treat stomach and duodenal ulcers and reflux of stomach acid into the esophagus. Nizatidine is available as the prescription drug and as a nonprescription product for relief of heartburn, acid indigestion, and sour stomach.

Summary of Interactions with Vitamins, Herbs, & Foods
Types of interactions:

Replenish Depleted Nutrients
-
Copper
There is some evidence that other vitamins and minerals, such as folic acid and copper, require the presence of stomach acid for optimal absorption. Long-term use of H-2 blockers may therefore promote a deficiency of these nutrients. Individuals requiring long-term use of H-2 blockers may therefore benefit from a multiple vitamin/mineral supplement.
-
Folic Acid
Folic acid is needed by the body to utilize vitamin B12. Antacids, including nizatidine, inhibit folic acid absorption. However, folic acid supplementation can mask a vitamin B12 deficiency. Therefore, people taking antacids are advised to supplement with folic acid and vitamin B12.

-
Vitamin B12
Stomach acid is needed for vitamin B12 in food to be absorbed by the body. H-2 blocker drugs reduce stomach acid and may therefore inhibit absorption of the vitamin B12 naturally present in food. However, the vitamin B12 found in supplements does not depend on stomach acid for absorption. Lab tests can determine vitamin B12 levels in people.
-
Beta-Carotene
Omeprazole
, a drug closely related to lansoprazole, taken for seven days led to a near-total loss of stomach acid in healthy people and interfered with the absorption of a single administration of 120 mg of beta-carotene. It is unknown whether repeated administration of beta-carotene would overcome this problem or if absorption of carotenoids from food would be impaired. Persons taking omeprazole and related acid-blocking drugs for long periods may want to have carotenoid blood levels checked, eat plenty of fruits and vegetables, and consider supplementing with carotenoids.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
-
Iron
Stomach acid may increase absorption of iron from food. H-2 blocker drugs reduce stomach acid and are associated with decreased dietary iron absorption. The iron found in supplements is available to the body without the need for stomach acid. People with ulcers may be iron deficient due to blood loss. If iron deficiency is present, iron supplementation may be beneficial. Iron levels in the blood can be checked with lab tests.

-
Magnesium
In healthy people, a magnesium hydroxide/aluminum hydroxide antacid, taken with nizatidine, decreased nizatidine absorption by 12%. People can avoid this interaction by taking nizatidine two hours before or after any aluminum/magnesium-containing antacids. Some magnesium supplements such as magnesium hydroxide are also antacids.
Potential Negative Interaction
The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
