Medication dosage refers to the specific amount of a medication that a patient should take at one time or over a certain period. It is usually determined by factors such as the patient's age, weight, and medical condition. Proper dosage is crucial for the medication to be effective and to minimize the risk of side effects. Dosages can be expressed in various units, such as milligrams (mg) or milliliters (mL). Healthcare providers, including doctors and pharmacists, calculate the appropriate dosage based on established guidelines and individual patient needs. Following the prescribed dosage is essential for safe and effective treatment.
