Amlodipine is a medication used to treat high blood pressure (hypertension) and chest pain (angina). Here are some specific uses of amlodipine:
- Hypertension: Amlodipine is commonly used to treat high blood pressure, either alone or in combination with other blood pressure-lowering medications.
- Angina: Amlodipine is also used to treat chest pain caused by reduced blood flow to the heart (angina), especially chronic stable angina and vasospastic (Prinzmetal’s) angina.
- Coronary artery disease: Amlodipine may be prescribed to people with coronary artery disease to help reduce the risk of heart attack and stroke.
- Raynaud’s disease: Amlodipine can also be used to treat Raynaud’s disease, a condition in which blood flow to the fingers and toes is restricted, causing them to turn pale, blue, or red.
- Heart failure: Amlodipine may be used in certain cases of heart failure, but it is not typically the first-line medication for this condition.
As with any medication, amlodipine should only be taken under the guidance of a healthcare professional, and the dosage and duration of treatment will depend on the individual’s condition and response to the medication.
Side effects of Amlodipine
Like all medications, amlodipine can cause side effects, although not everyone will experience them. Some of the common side effects of amlodipine include:
- Swelling: Amlodipine may cause swelling of the ankles, feet, or hands. This is caused by fluid retention and is more common in people who are elderly or have kidney disease.
- Headache: Headache is a common side effect of amlodipine, particularly during the first few weeks of treatment.
- Dizziness: Amlodipine can cause dizziness, especially when standing up or getting up from a seated or lying position.
- Flushing: Some people may experience flushing or redness of the face or skin after taking amlodipine.
- Nausea: Amlodipine can cause nausea or stomach upset, particularly when first starting the medication.
- Fatigue: Amlodipine may cause fatigue or drowsiness, especially during the first few weeks of treatment.
Less common but more serious side effects of amlodipine include allergic reactions, low blood pressure, and liver problems. If you experience any of these serious side effects, seek medical attention immediately. It is important to talk to your healthcare provider if you have any concerns about the potential side effects of amlodipine or any other medication you are taking.
How to treat high blood pressure with Amlodipine
Amlodipine is a medication used to treat high blood pressure, and it is typically taken once a day, either alone or in combination with other blood pressure-lowering medications. Here are some guidelines for treating high blood pressure with amlodipine:
- Follow your healthcare provider’s instructions: Always take amlodipine exactly as prescribed by your healthcare provider, and do not adjust your dosage or stop taking the medication without first consulting with your healthcare provider.
- Take the medication at the same time every day: Amlodipine should be taken at the same time every day, either with or without food.
- Monitor your blood pressure regularly: It is important to monitor your blood pressure regularly, as directed by your healthcare provider. This will help you and your healthcare provider determine if the medication is working effectively.
- Make lifestyle changes: In addition to taking medication, making certain lifestyle changes can also help lower your blood pressure. These include eating a healthy diet, maintaining a healthy weight, exercising regularly, quitting smoking, and limiting alcohol consumption.
- Report any side effects: If you experience any side effects from amlodipine, such as swelling or dizziness, talk to your healthcare provider right away. They may need to adjust your dosage or switch you to a different medication.
It is important to remember that amlodipine is just one part of a comprehensive approach to managing high blood pressure. Be sure to follow all of your healthcare provider’s instructions and make any necessary lifestyle changes to help control your blood pressure.
Amlodipine Interactions
Amlodipine can interact with other medications, supplements, and foods, which can affect its effectiveness or increase the risk of side effects. Here are some important interactions to be aware of:
- Other medications that lower blood pressure: Amlodipine can enhance the blood pressure-lowering effects of other medications, such as ACE inhibitors, ARBs, and diuretics. This can increase the risk of low blood pressure and other side effects.
- Grapefruit and grapefruit juice: Grapefruit and grapefruit juice can interact with amlodipine, increasing the amount of the medication in your bloodstream and potentially increasing the risk of side effects.
- CYP3A4 inhibitors: Amlodipine is metabolized by the liver enzyme CYP3A4, and medications that inhibit this enzyme can increase the amount of amlodipine in the bloodstream, increasing the risk of side effects. Examples of CYP3A4 inhibitors include certain antibiotics, antifungal medications, and protease inhibitors.
- CYP3A4 inducers: Medications that induce the activity of CYP3A4 can decrease the amount of amlodipine in the bloodstream, reducing its effectiveness. Examples of CYP3A4 inducers include certain anticonvulsants, rifampin, and St. John’s wort.
- Potassium-sparing diuretics: Amlodipine can increase the level of potassium in the bloodstream, and combining it with potassium-sparing diuretics, such as spironolactone or triamterene, can increase the risk of high potassium levels (hyperkalemia).
It is important to talk to your healthcare provider and pharmacist about all medications, supplements, and foods you are taking while on amlodipine. They can help you understand any potential interactions and help you avoid them.
Amlodipine Dosage
The dosage of amlodipine can vary depending on the individual’s medical condition, age, and other medications they may be taking. It is important to follow your healthcare provider’s instructions for taking amlodipine and to not adjust your dose or stop taking the medication without consulting with your healthcare provider. Here are some general guidelines for amlodipine dosage:
- For hypertension: The usual starting dose for treating hypertension (high blood pressure) in adults is 5 mg once daily, with a maximum dose of 10 mg once daily. The starting dose for elderly patients or patients with liver impairment may be lower.
- For angina: The usual starting dose for treating chronic stable or vasospastic angina is 5 mg once daily, with a maximum dose of 10 mg once daily. The starting dose for elderly patients or patients with liver impairment may be lower.
- For children: The dosage of amlodipine for children is based on their body weight and is determined by the healthcare provider.
- Renal impairment: Amlodipine is excreted by the kidneys, and dosage adjustments may be necessary in patients with renal impairment.
It is important to take amlodipine at the same time each day, with or without food. If you miss a dose of amlodipine, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
As with any medication, it is important to talk to your healthcare provider if you have any questions or concerns about the appropriate dosage of amlodipine for your specific condition.
Precautions should be taken when using Amlodipine
Amlodipine is a medication used to treat high blood pressure and certain types of angina. Here are some precautions to be aware of when using amlodipine:
- Avoid grapefruit and grapefruit juice: Grapefruit and grapefruit juice can interact with amlodipine and increase the amount of the medication in your bloodstream, which can increase the risk of side effects.
- Pregnancy and breastfeeding: Amlodipine should be used with caution during pregnancy and breastfeeding, as it can cross the placenta and pass into breast milk. Women who are pregnant or breastfeeding should talk to their healthcare provider before taking amlodipine.

- Kidney impairment: Amlodipine is excreted in the urine, and patients with severe kidney impairment may need to take a lower dose of the medication.
- Elderly patients: Elderly patients may be more susceptible to the blood pressure-lowering effects of amlodipine and may require a lower starting dose.
- Other medical conditions: Amlodipine should be used with caution in patients with heart failure or aortic stenosis, as it can worsen these conditions. Patients with hypotension (low blood pressure) should also use amlodipine with caution.
- Medication interactions: Amlodipine can interact with other medications, supplements, and foods, so it is important to talk to your healthcare provider and pharmacist about all medications you are taking.
