Take special care with Amdocal Plus
Atenolol may mask the symptoms of hyperthyroidism. It may also mask the symptoms of hypoglycaemia, as well as enhancing the effects of hypoglycemic agents in patients with diabetes mellitus.

Taking other medicines
Atenolol: The effects of other myocardial depressant agents, including anti-arrhythmics such as Quinidine, Procainamide, or Lignocaine, Phenytoin, and medicines which interfere with calcium transport, such as Verapamil, may also be enhanced by Atenolol.
The effects of Atenolol are diminished by beta-adrenoceptor stimulating agents such as Isoprenaline; the hypotensive effects of Atenolol may be dangerously reversed and the peripheral vasoconstrictor effects enhanced by alpha-adrenoceptor stimulating agents such as noradrenaline or those with mixed alpha- and beta-adrenoceptor stimulating properties such as adrenaline; bradycardia may also occur.
The effects of Atenolol may be enhanced by adrenergic neuron blocking agents such as Guanethidine or Bethanidine, or Catecholamine-depleting agents such as Reserpine and the hypotensive effects by diuretics. Atenolol may enhance some of the cardiac effects of digitalis and diminish others. It has been suggested that clonidine withdrawal symptoms may be exacerbated in patients who are concurrently taking a beta blocker.

Pregnancy and breast-feeding
Atenolol crosses the placenta. So it is contraindicated in pregnancy and lactation.

4. Possible side effects
Like all medicines, Amdocal Plus can cause side effects, although not everybody gets them.
Amlodipine: Peripheral edema may occasionally be present but is fully reversible. As with other calcium channel blockers peripheral edema and skin erythema occur in a proportion of patients and facial flushing occurs in 2-5% of patients. Complaints of fatigue were also reported more frequently than in placebo-treated patients. There is evidence that these effects are more common in patients treated with doses greater than 10 mg daily.
Atenolol: Pronounced fatigue and cold extremities have been observed in 10 to 20% of the treated subjects. Complaints about bradycardia, dizziness and gastrointestinal symptoms are less frequent. Despite its relative selectivity, Atenolol can cause bronchospasms in asthma patients.

Tell your doctor if any of the side effects gets serious or lasts longer than a few days, or if you notice any side effects not listed in this leaflet
