Key takeaways
Lomaira (phentermine) and phentermine (Adipex-P) are both sympathomimetic medications used for short-term weight management in adults with a BMI of 30 kg/m² or greater, or 27 kg/m² with a weight-related condition. Both medications contain phentermine, but they differ in their dosing and formulation. Lomaira is taken three times a day, 30 minutes before meals, while phentermine (Adipex-P) is typically taken once daily, either before breakfast or 1 to 2 hours after breakfast. Adipex-P offers more flexibility with its dosage forms, including tablets, capsules, and orally disintegrating tablets, whereas Lomaira is only available in tablets. Lomaira is a shorter-acting version, while Adipex-P provides a longer duration of action. Both medications share common side effects like dry mouth, trouble sleeping, and headache, and both interact with alcohol. Both medications are available as a lower-cost generic.
