Pregnancy: Category X. This medicine should not be used during pregnancy as it may be harmful to the unborn baby. Lactation: Significant amounts of this medicine may pass into breast milk. It should not be used by breastfeeding mothers as it may be harmful to the nursing infant.

Not to be taken regularly or used for migraine prophylaxis. Increased risk of arterial constriction and other symptoms of ergotism. Discontinue treatment when symptoms of arterial occlusion occur e.g. numbness and tingling of the extremities. Caution when used in patients with infective hepatitis, cardiac disease or anaemia. GI tract obstructive disease, glaucoma, prostatic hypertrophy or urinary retention may be worsened by cyclizine. May increase risk of retroperitoneal and/or pleuropulmonary fibrosis. Not recommended for use with other vasoconstrictors. Elderly.

Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Renal Dose Adjustments: Contraindicated in patients with renal dysfunction Liver Dose Adjustments: Contraindicated in patients with liver dysfunction

Acute overdosage: Symptoms: Nausea, vomiting, diarrhoea, extreme thirst, coldness, weakness, tingling and itching of the skin, rapid and weak pulse, hypotension, shock, confusion, convulsions and unconsciousness. BP may be difficult to measure; may result in fatalities. Further symptoms of peripheral vasoconstriction or CV disturbances may occur but be delayed. Treatment includes using activated charcoal to reduce absorption. General supportive measures should be instituted. IV vasodilators such as sodium nitroprusside infusion may be required to relieve vasospasm. Peritoneal dialysis and forced diuresis may be used to remove ergotamine from the body. Chronic overdosage: Symptoms: Peripheral ischaemia of the extremities, especially the feet and legs. Gangrene may develop in the toes and fingers. Anginal pain, tachycardia or bradycardia and BP fluctuations may occur. Excessive use may lead to pleural and peritoneal fibrosis. Rebound headache may occur and is a major withdrawal symptom following the development of ergotamine dependence. Treatment: IV vasodilators e.g. nitroprusside and nitroglycerin may be used to re-establish normal blood flow. Captopril may be used to reverse the effects of chronic overdosage with ergotamine.
