Prescription pharmaceuticals are medications that require a doctor's approval before they can be obtained. These drugs are used to treat various medical conditions, ranging from infections to chronic diseases. A healthcare professional evaluates a patient's health needs and prescribes the appropriate medication, dosage, and duration of treatment. These medications are typically dispensed at pharmacies and are regulated by government agencies to ensure safety and effectiveness. Common examples of prescription pharmaceuticals include antibiotics for infections, antidepressants for mental health issues, and antihypertensives for high blood pressure. Proper use of these medications is essential for achieving the desired health outcomes.
