  • Patients with known hypersensitivity to cimetidine or to any ingredient of the drug.


  • Adverse reactions to cimetidine and other histamine H2-antagonists are generally infrequent. The commonest adverse effects reported have been diarrhoea and other gastrointestinal disturbances, dizziness, tiredness, headache, and rashes.
  • Altered liver function tests have occurred and there have been rare reports of hepatotoxicity. Reversible confusional states, especially in the elderly or in seriously ill patients such as those with renal failure, have occasionally occurred. Other adverse effects that have been reported rarely are hypersensitivity reactions and fever, arthralgia and myalgia, blood disorders including agranulocytosis and thrombocytopenia, acute pancreatitis, hallucinations and depression, and cardiovascular disorders including bradycardia and heart block.
  • Cimetidine has a weak anti-androgenic effect and gynaecomastia and impotence have also occasionally occurred in men receiving relatively high doses for conditions such as the Zollinger-Ellison syndrome.


  • Before giving cimetidine or other histamine H2-antagonists to patients with gastric ulcers the possibility of malignancy should be considered since these drugs may mask symptoms and delay diagnosis.
  • Pregnancy: There are no adequate and controlled studies to date using cimetidine in pregnant women, and the drug should be used during pregnancy only when clearly needed.
    Lactation: Since cimetidine is distributed into milk, nursing should generally not be undertaken during therapy with the drug.
  • Effect on ability to drive and use machines: None known.
