Understanding the uses, dosage, and potential side effects of a medication is crucial for safe administration and optimal effect. The ‘uses’ of a medication describe the conditions that the drug can treat or prevent. The ‘dosage’ refers to how much, how often, and for how long to take the medicine. It’s important to follow the recommended dosage to avoid the risk of ‘side effects’ which can range from mild discomfort to serious, potentially life-threatening conditions.
