Amlodipine is a widely used medication that belongs to a class of drugs known as calcium channel blockers. It is primarily prescribed to manage high blood pressure, also known as hypertension, and to alleviate chest pain caused by angina. This medication works by relaxing the blood vessels, which allows blood to flow more easily and reduces the workload on the heart, thereby improving blood circulation throughout the body.
Understanding Amlodipine’s Standard Dosage
Amlodipine is prescribed for once-daily administration. Its prolonged half-life, ranging from 30 to 50 hours, allows it to maintain steady therapeutic levels over a full 24-hour period. This single daily dose ensures continuous blood pressure control or angina management throughout the day and night. Peak plasma concentrations are reached between 6 and 12 hours after a dose. Consistent daily dosing leads to steady-state plasma levels within 7 to 8 days.
Why Altering Your Amlodipine Dosage Is Not Recommended
Taking amlodipine more frequently than prescribed, such as twice a day, is not advised without medical guidance. The dosage is determined by a healthcare provider based on an individual’s health needs and response to the medication. Increasing the frequency or amount of amlodipine without medical consultation can lead to an excessive drop in blood pressure, a condition known as hypotension.
Symptoms of hypotension include dizziness, lightheadedness, and blurry vision. This can also heighten the risk of other side effects, such as swelling in the ankles or feet, headache, or flushing. These effects may impact daily activities.
When to Consult Your Healthcare Provider
Adhere to your doctor’s instructions regarding amlodipine dosage and frequency. If you have questions about your amlodipine, or if your prescribed dose is not controlling your blood pressure or angina symptoms, contact your healthcare provider or pharmacist. They can assess your condition and determine if any adjustments are necessary.
If a dose of amlodipine is missed, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Never take a double dose, as this can increase the risk of side effects. Only a healthcare professional can safely modify your medication schedule.
