The information below describes dosages that are commonly prescribed. That said, always take the dosage your doctor prescribes for you. Your doctor will determine the dosage that best meets your needs.
Dosage for high blood pressure and coronary artery disease
The following table shows the recommended dosages for approved uses of amlodipine oral tablets in adults. Starting dosages for high blood pressure depend on age and liver function. Dosages for coronary artery disease also depend on these factors.
|Condition||Recommended dose range||Maximum dose||Frequency|
|high blood pressure||2.5 mg to 10 mg*||10 mg||once per day|
|coronary artery disease, including angina†||5 mg to 10 mg||10 mg||once per day|
* Doctors prescribe a lower starting dose and maintenance dose to certain people. In these people, their body removes the drug more slowly. They include older adults (usually ages 65 years and older). They also include people who are smaller in size and people with liver problems. But most adults take 10 mg per day.
† Angina is chest pain related to coronary artery disease.
If you take amlodipine for high blood pressure, your doctor will monitor how it’s working for you. They may increase your dose slightly every 7 to 14 days until it provides the desired outcome. The maximum dosage is 10 mg once per day.
Similarly, if you take amlodipine for coronary artery disease, your doctor will monitor how it’s working for you. A dosage of 10 mg per day is common for managing this condition.
Dosages of amlodipine in children
Amlodipine oral tablets are approved to treat high blood pressure in children ages 6 to 17 years. Your child’s typical dosage will be 2.5 mg to 5 mg once per day.
Children usually won’t take more than 5 mg once per day. This is because higher dosages haven’t been studied in children.
Dosage adjustments for amlodipine
Your doctor will prescribe a dosage of amlodipine oral tablets based on several factors. These include:
- the specific condition being treated and how severe it is
- your age
- other health conditions you may have
If you have liver problems, your doctor may start you on a lower dosage of amlodipine. Your liver removes amlodipine from your body. If it works more slowly, you may have more amlodipine in your blood. This can lead to a higher risk of side effects.
Doctors also may prescribe a lower dosage of amlodipine for children and older adults. (Older adults are usually considered ages 65 years and older.) Children often have lower body weight, or their body processes the drug differently. And older adults may have a higher risk of side effects, such as dizziness.
Check with your doctor if you have questions about dosage adjustments for amlodipine oral tablets.
Missed dose of amlodipine
If you miss a dose of amlodipine oral tablets, note when the dose was due. If it was due fewer than 12 hours ago, take it as soon as you remember. If it was due more than 12 hours ago, skip the missed dose. Then, take your next dose as scheduled. Do not take two doses at a time.

Frequently asked questions
This section presents answers to some questions commonly asked about amlodipine oral tablets and their dosages.
Is the dosage of amlodipine the same as the dosage of amlodipine besylate?
Yes, it’s the same. Amlodipine besylate is the full name of amlodipine. It’s also the active ingredient that makes amlodipine work. Most doctors and pharmacists refer to the drug as amlodipine.
If you have questions about your dosage of amlodipine oral tablets, check with your doctor or pharmacist.
Do doctors prescribe an amlodipine dosage taken twice daily?
No, they usually don’t. Once you start taking amlodipine, one dose is effective for 24 hours in your body. This means you don’t need to take it more than once per day.
Your doctor will prescribe the dose and timing of amlodipine oral tablets that are best for you. They may suggest that you take your dose at the same time each day. Read about ways to remember to take your medication on time in this article.
Is there a recommended amlodipine dose for older people?
Sometimes doctors prescribe a lower dose of amlodipine oral tablets for older adults. (Older adults are usually considered ages 65 years and older.) Your doctor will consider certain factors and prescribe the dose that’s best for you.
Some people taking amlodipine oral tablets have side effects of dizziness and low blood pressure. These side effects may happen more often in older adults. Because of this, older adults should be monitored closely to avoid falls and injury.
If you’re an older adult, you may start treatment with a lower dose. You and your doctor will watch to see how the drug might affect you.
Your liver removes amlodipine from your body, but older adults sometimes have reduced liver function. Doctors may prescribe a lower starting dose for older adults. Then they’ll monitor how well the liver removes the drug. If side effects are bothersome, the dose may stay low. Or the doctor may recommend another medication.
Check with your doctor if you want to learn more about the dosages of amlodipine in older people.
What is a typical amlodipine plus benazepril dosage?
Doctors use a range of dosages when prescribing a combination product of amlodipine and benazepril. (Benazepril lowers blood pressure, but it works differently from amlodipine.) The brand name of this combination product is Lotrel.
Dosages for Lotrel range from 2.5 milligrams (mg) amlodipine/10 mg benazepril to 10 mg amlodipine/40 mg benazepril. If you’re just starting on Lotrel, you’ll typically start with its lowest dosage. If you already take amlodipine or benazepril alone, your starting dosage of Lotrel may match the medication you’re taking.
Check with your doctor if you have questions about Lotrel’s dosage.
Is amlodipine used long term?
Yes, doctors typically prescribe amlodipine oral tablets as a long-term treatment.
If you and your doctor feel it’s safe and effective for your condition, you’ll likely take it long term.
