From the Guidelines
Increasing amlodipine from 10mg to 15mg daily is not recommended as the usual dose range for amlodipine is 2.5–10 mg/d, according to the seventh report of the joint national committee on prevention, detection, evaluation, and treatment of high blood pressure 1.
Key Considerations
- The maximum recommended dose of amlodipine is 10mg once daily, and exceeding this dose may not provide significant additional blood pressure reduction but can increase the risk of side effects.
- Alternative approaches to managing uncontrolled blood pressure include adding a second antihypertensive medication from a different class, such as an ACE inhibitor, ARB, or thiazide diuretic, which can target different blood pressure control mechanisms.
- Before making any medication changes, it is essential to consult with a healthcare provider to evaluate the specific situation, including blood pressure readings, side effects, and other medical conditions.
Potential Risks and Benefits
- Increasing the dose of amlodipine beyond 10mg may lead to increased risks of side effects such as peripheral edema, headaches, and dizziness, without providing significant additional blood pressure reduction.
- Combination therapy with medications from different classes can be more effective in controlling blood pressure and may have a more favorable side effect profile.
- It is crucial to rule out causes of apparent treatment resistance, such as white coat hypertension, improper blood pressure measurement technique, or medication non-adherence, before making any changes to the treatment plan.
Recommendations
- Consult with a healthcare provider to evaluate the specific situation and determine the best course of action for managing uncontrolled blood pressure.
- Consider alternative approaches, such as adding a second antihypertensive medication from a different class, rather than exceeding the maximum recommended dose of amlodipine.
- Monitor blood pressure readings and side effects closely to determine the effectiveness of the treatment plan and make adjustments as needed.

From the Research
Amlodipine Dosage
- The studies provided do not directly address the specific dosage increase from 10mg to 15mg of amlodipine 2, 3, 4, 5, 6.
- However, the evidence suggests that amlodipine is effective in reducing blood pressure in hypertensive patients, with a common dosage range of 5-10mg 3, 5.
- One study mentions that side effects of amlodipine are more common with the higher dose of 10mg, but does not provide information on doses above 10mg 5.
- There is no direct evidence to support the safety and efficacy of increasing the dosage from 10mg to 15mg, and this decision should be made under medical supervision.
Blood Pressure Reduction
- Amlodipine has been shown to be effective in reducing blood pressure in hypertensive patients, with significant reductions in systolic and diastolic blood pressure 2, 3, 5, 6.
- The studies suggest that amlodipine can be used as monotherapy or in combination with other antihypertensive agents to achieve blood pressure control 3, 6.
- The evidence also highlights the importance of optimizing amlodipine titration to achieve adequate blood pressure control, particularly in high-risk populations such as diabetic patients 2.
