Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

High doses of nicotinic acid may cause hyperpigmentation, abdominal cramps, diarrhoea, nausea and vomiting, anorexia, activation of peptic ulcer, jaundice, impairment of liver function, decrease in glucose tolerance, hyperglycaemia and hyperuricaemia. Excessive intake of calcium salts and vitamin D may lead to hypercalcaemia. Toxic effects should normally subside without treatment.

5. Pharmacological properties
5.1 Pharmacodynamic properties

A12A X-Calcium, combinations with other drugs.

Crampex Tablets contain three active ingredients, calcium gluconate, nicotinic acid and Cholecalciferol. The inclusion of calcium gluconate is intended to correct any sub-clinical deficiency of calcium that may exist. The vitamin D status of the elderly may border on the deficient and as their vitamin D intake is often inadequate, Cholecalciferol is contained in the formulation to ensure satisfactory calcium absorption. As it is possible that a poor peripheral circulation may be an aggravating factor in the induction of cramps, the formulation includes the vasodilator, nicotinic acid.
