What is the usual maximum dose of losartan for adults?
For most adults, the maximum recommended daily dose of losartan is 100 mg once daily.
Maximum dose for specific conditions (hypertension, kidney protection, heart failure)
Losartan’s maximum dose is commonly 100 mg per day across indications where it’s used, including high blood pressure and kidney-protective regimens in appropriate patients. For heart failure, dosing is also titrated upward toward the same upper limit based on tolerability and the prescriber’s plan.
What if the patient has kidney problems or is on dialysis?
Losartan is often still used up to the usual maximum (100 mg/day), but clinicians typically adjust carefully and monitor closely because kidney function affects overall safety. Dose adjustments and monitoring can be more important if the patient is also at higher risk of potassium elevation.
What if the patient’s potassium is high?
The main safety monitoring that can limit how high losartan can be titrated is hyperkalemia (high potassium). If potassium rises, the prescriber may reduce the dose or stop losartan, and they may also change other medicines that raise potassium.
Can the maximum dose differ for children?
Yes. Pediatric dosing is weight-based and titrated to a target, with a maximum daily dose that depends on age/indication and the dosing regimen used by the prescribing information.
Sources
I don’t have the specific losartan labeling/table you need in the provided information to cite an exact “maximum dosage” statement (for adults or for children) from a primary source.
If you share which country’s labeling you’re using (US FDA, UK, Canada, etc.) or the patient’s age and indication (hypertension vs kidney protection vs heart failure), I can give the correct maximum dose for that scenario.
