About Lomaira For Weight Loss

Low-dose appetite suppressant taken before meals to support short-term weight loss alongside diet and exercise.

Lomaira dosing must be individualized to find the lowest effective dose for your lifestyle: 

  • Standard Dosage: One 8 mg tablet taken three times daily.
  • Timing: Administer the tablet 30 minutes before each main meal.
  • Flexible Splitting: The 8 mg tablets are butterfly-scored, allowing them to easily be split in half for a 4 mg dose if less medication is needed at a certain time of day.
  • Sleep Protection: Avoid late evening dosing to minimize the risk of insomnia or trouble sleeping.

While Lomaira is a low-dose option, its active stimulant mechanism can cause side effects as your body adjusts. Most side effects are mild and typically improve within the first few weeks of treatment. 

  • Gastrointestinal: Dry mouth, unpleasant or metallic taste, constipation, or diarrhea.
  • Central Nervous System: Restlessness, nervousness, headache, dizziness, and mild tremors.
  • Sleep Disruption: Insomnia or trouble falling asleep. (Tip: Avoid taking your final 8 mg dose in the late evening to reduce sleep issues).
  • Cardiovascular Changes: Palpitations, mild increases in heart rate, or elevated blood pressure.
  • Changes in Mood or Libido: Occasional changes in sexual drive or feelings of overstimulation.

Lomaira and Adipex-P contain the exact same active weight-loss ingredient (phentermine), but they differ primarily in their dosage strength, frequency, and flexibility

Short‑term stimulant appetite suppressant to reduce appetite and food cravings taken once daily.  


  • Who it may help: Patients needing an initial metabolic jump‑start who have no cardiovascular contraindications.
  • How to take: Once daily in the morning.
