DOSING: Ranitidine may be taken with or without food.
Self-medication should not last longer than 2 weeks unless advised by a physician.
DRUG INTERACTIONS: Ranitidine, 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).
PREGNANCY: There are no adequate studies of ranitidine in pregnant women. Available evidence suggests that there is little risk when used during pregnancy.
NURSING MOTHERS: Ranitidine is secreted into human breast milk and may pose a potential risk to the infant.
SIDE EFFECTS: Minor side effects include constipation, diarrhea, fatigue, headache, insomnia, muscle pain, nausea, and vomiting. Major side effects are rare; they include: agitation, anemia, confusion, depression, easy bruising or bleeding, hallucinations, hair loss, irregular heartbeat, rash, visual changes, and yellowing of the skin or eyes.
