Pregnancy & Lactation

The combination should be used during pregnancy only if the expected benefit outweighs the potential fetal risk. The combination should not be used by nursing mothers. If its use is considered necessary, breast-feeding should be stopped.

Precautions & Warnings

Bronchospasm: The combination should be used with caution in patients with airway obstruction.

Renal impairment: The combination can be used in patients with renal impairment. However, caution may be necessary if the creatinine clearance is less than 30 ml/min because of possible reduction in the excretion of unchanged Atenolol.

Hepatic impairment: Caution may be necessary in the use of the combination in patients with severe liver damage because of prolongation of the elimination half-life of Amlodipine.

Drug withdrawal: Since coronary heart disease may exist without being recognized, patients should be warned against stopping the drug suddenly. Any discontinuation should be gradual and under observation.
