Vanliga misstag att undvika

• ✕Comparing short-term trial data (12 weeks for phentermine) with long-term data (68 weeks for semaglutide)
• ✕Not considering that some medications are FDA-approved for short-term use only (phentermine)
• ✕Ignoring contraindications — not all medications are safe for all patients (e.g., phentermine is contraindicated with uncontrolled hypertension)
