DRUG INTERACTIONS: Nizatidine, like other drugs that reduce stomach acid, may interfere with the absorption of drugs that require acid for adequate absorption. Examples include iron salts (for example iron sulphate), itraconazole (Sporanox), and ketoconazole (Nizoral, Extina, Xolegel, Kuric), atazanavir (Reyataz), dasatinib (Sprycel), indinavir (Crixivan), and dapsone. Conversely, it may increase levels of nimodipine (Nimotop) and nisoldipine (Sular) due to reduced stomach acidity.
