5. Tips

6. Response and effectiveness

Peak concentrations of valsartan occur within two to four hours of dosing. May take up to two weeks for substantial blood pressure-lowering to occur; peak blood pressure-lowering effects are attained after four weeks. Some doctors may use a higher dosage initially or add a diuretic (water pill) if faster blood pressure reduction is required. Blood pressure lowering effects of a daily dose are maintained for at least 24 hours.

7. Interactions

Medicines that interact with valsartan may either decrease its effect, affect how long it works, increase side effects, or have less of an effect when taken with valsartan. An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. Speak to your doctor about how drug interactions should be managed.

Common medications that may interact with valsartan include:

People taking oral medications for diabetes may need to talk to their doctor about adjusting the dose of their medicine.

Note that this list is not all-inclusive and includes only common medications that may interact with valsartan. You should refer to the prescribing information for valsartan for a complete list of interactions.
