Do not take an antacid within 1 hour before or 2 hours after you take Nizoral . If you are also taking an anticholinergic (eg, hyoscyamine), an H2 antagonist (eg, famotidine), or a proton pump inhibitor (eg, omeprazole), take Nizoral at least 2 hours before the H2 antagonist, proton pump inhibitor, or anticholinergic.
