To be used with caution, or not at all, for people with the following conditions: * Heart disease * Impaired kidney or liver function * Narrow angle glaucoma * In the immediate recovery period after myocardial infarction * In arrhythmias (particularly heart block) * Mania * In severe liver and/or severe renal impairment And in those being treated with amiodarone or terfenadine. Pregnancy and lactation<unk>  use during pregnancy is advised against unless the benefits clearly outweigh the risks. This is because its safety during pregnancy has not been established and animal studies have shown some potential for harm if used during pregnancy. If used during the third trimester of pregnancy it can cause insufficient breathing to meet oxygen requirements, agitation and withdrawal symptoms in the infant. Likewise its use by breastfeeding women is advised against, except when the benefits clearly outweigh the risks, due to the fact it is excreted in the breast milk and may therefore adversely affect the infant. Although the amount secreted in breast milk is likely too small to be harmful.
