Edit list (add/remove drugs)

Interactions between your drugs

Moderate

atenolol chlorthalidone

Applies to: atenolol / chlorthalidone and atenolol / chlorthalidone

Using atenolol and chlorthalidone together may lower your blood pressure and slow your heart rate. This can cause dizziness, or feeling like you might pass out, weakness, fainting, fast or irregular heartbeats, or loss of blood glucose control. If you take both medications together, tell your doctor if you have any of these symptoms. You may need a dose adjustment or need your blood pressure checked more often to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) and diuretics may adversely affect renal function due to NSAID inhibition of the renal synthesis of prostaglandins that help maintain renal perfusion in dehydrated states. The risk may be increased in patients on dietary sodium restriction. At the same time, hypotensive effect of the diuretics may be reduced because inhibition of prostaglandins can lead to unopposed pressor activity and, consequently, elevation in blood pressure. Natriuretic and diuretic effects may also be reduced, as NSAIDs have been reported to cause sodium and water retention, which may account for the increased risk of congestive heart failure associated with the combination. One study showed an increase in the incidence density of congestive heart failure (in patients over 55 years of age) from 9.3 per 1,000 person-years in patients on diuretics to 23.3 per 1,000 person-years in patients on both diuretic and NSAID therapy. NSAIDs may also increase the risk of hyperkalemia associated with potassium-sparing diuretics.

MANAGEMENT: In patients receiving both diuretic and NSAID therapy, management consists of avoiding dehydration and carefully monitoring the patient's renal function and blood pressure. If renal insufficiency or hyperkalemia develops, both drugs should be discontinued until the condition is corrected.

Atenolol and ethanol (alcohol) may have additive effects in lowering your blood pressure. You may experience headache, dizziness, lightheadedness, fainting, and/or changes in pulse or heart rate. These side effects are most likely to be seen at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
