Key takeaways:
Amlodipine (Norvasc) is a medication that’s approved to treat high blood pressure and coronary artery disease (CAD) in adults. It can also be used for high blood pressure in children as young as 6 years old.
The usual amlodipine dosage in adults is 5 mg to 10 mg once daily. But if you have liver problems, take medications that increase amlodipine levels, or you’re of older age, your dose may be lower.
Amlodipine tablets are available as a brand-name medication and lower-cost generic. You can find generic amlodipine tablets for as low as $10 a month with a free GoodRx discount.
Amlodipine is part of a group of medications called calcium channel blockers. It’s available as an oral tablet (Norvasc), oral solution (Norliqva), and oral suspension (Katerzia). It’s FDA approved to treat high blood pressure and coronary artery disease (CAD) in adults. It’s also approved to treat high blood pressure in children as young as 6 years old.
Here, we’ll take a look at typical amlodipine doses recommended by the medication’s manufacturer. Your healthcare provider may recommend a different dose than what’s listed here, so make sure you always follow their instructions closely.
Adults typically take amlodipine once daily. It can be taken any time of day, with or without food. But try to take your amlodipine dose at the same time every day. This not only helps you remember to take it, but also keeps a steady amount of medication in your body throughout the day.
All forms of amlodipine are FDA approved to treat high blood pressure and CAD. CAD happens when the arteries (a type of blood vessel) that bring oxygen-rich blood to your heart become damaged.
Calcium channel blockers, like amlodipine, are a first-choice medication for high blood pressure. Your healthcare provider will usually start you at 5 mg once a day. They may increase your dose up to 10 mg.
It may take a few weeks to find the best amlodipine dose for you. This is because your provider may wait a week or longer before increasing your dose to see how it affects you. In some cases, they may increase your dose more rapidly and ask you to check in more frequently.
The typical dose of amlodipine for CAD is 5 mg to 10 mg once daily. Most people will end up needing 10 mg.
When treating high blood pressure, children may need a lower amlodipine dosage than adults.
For children as young as 6 years old, the amlodipine dose usually ranges from 2.5 mg to 5 mg.
Some people may need a lower amlodipine dose than what’s recommended for the general population. The dose you’ll need may depend on your medical history, age, and other medications you take.
Amlodipine is broken down by the liver. So if you have liver problems before starting amlodipine, your healthcare provider may start you at a lower dose than usual. This is to prevent amlodipine from building up in your body, which may lead to side effects. Examples of possible amlodipine side effects include dizziness, fatigue, and blood pressure that’s too low.
Older adults are more likely to have liver, kidney, or heart issues. This may make them more sensitive to amlodipine. Typically, the starting amlodipine dose for older adults is lower (2.5 mg).
If you take amlodipine, it’s a good idea to ask your provider and pharmacist if you take any medications that can interact with amlodipine. Some medications, like ketoconazole, voriconazole (Vfend), and ritonavir (Norvir) may increase levels of amlodipine in the body. If you take one of these medications, you may need a lower dose of amlodipine.
If you miss a dose of amlodipine, take it right when you remember. But if it’s been more than 12 hours since you missed your dose, skip the missed dose. Then, just take your next dose at your usual time.
Don’t take two amlodipine doses at the same time to make up for a missed dose. This raises your risk of amlodipine side effects.
Taking too much amlodipine can raise your risk of side effects and toxicity, including dangerously low blood pressure and a fast heart rate. If you take too much amlodipine, you may feel the following symptoms:
Dizziness or light-headedness that leads to fainting
Shortness of breath
Headache
Chest pain
Nausea and vomiting
Heart palpitations
Flushing
If you or someone you know has taken too much amlodipine, medical care in a hospital may be necessary. Seek emergency care by calling 911, or call Poison Control at 1-800-222-1222.

Your amlodipine dosage depends on many factors, including your age, medical history, and other medications you take. Typically, the amlodipine dosage for high blood pressure or CAD is 5 mg to 10 mg once daily in adults. If you’re older, have liver problems, or take medications that interact with amlodipine, it may be lower. In children, the usual dose for high blood pressure is 2.5 mg to 5 mg once daily.
It’s best to take amlodipine at the same time each day. But it doesn’t matter what time of day you take it. And you can take it with or without food. If you forget a dose, take it as soon as you remember. Though, if it’s been over 12 hours since your missed dose, skip this dose and resume your normal dosing schedule. Never take two doses at once. This raises your risk of side effects.
