Dosage Reference
Reference Information Only
Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.
Adults:
The usual starting dose is Atenolol 50 mg combined with Chlorthalidone 25 mg, taken once daily. If blood pressure is not adequately controlled, another antihypertensive medicine may be added gradually, starting at about half the usual recommended starting dose, to prevent blood pressure from falling too sharply. Since Atenolol is cleared from the body by the kidneys, the dose should be adjusted for patients with severely impaired kidney function. Regarding use in the elderly: clinical studies of the Atenolol and Chlorthalidone combination did not enroll enough patients aged 65 and over to establish whether they respond differently than younger patients.

Atechlor produces side effects similar to those of its individual components. Atenolol: bradycardia, cold extremities, postural hypotension, leg pain, dizziness, vertigo, lightheadedness, tiredness, fatigue, lethargy, drowsiness, depression, dreaming, diarrhea, nausea, wheeziness, and dyspnea. Chlorthalidone: orthostatic hypotension, anorexia, gastric irritation, vomiting, cramping, constipation, vertigo, purpura, photosensitivity, rash, urticaria, hyperglycemia, glycosuria, hyperuricemia, muscle spasm, weakness, and restlessness.
