Many people take cimetidine only when they need it. However, for those who take it on a daily basis, if you do not take your cimetidine as scheduled, take your next dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose of cimetidine.
