Concerns related to adverse effects:
• GI: Severe abdominal pain or diarrhea may occur; discontinue use.
• Dysphagia: Use with caution in patients with dysphagia; may affect ability to swallow capsules.
• GI disease: Use with caution in patients with active GI disease, such as gastroesophageal reflux disease, heartburn, or ulcers. Avoid use in patients with esophageal anatomic anomalies (eg, diverticuli, rings, webs), suspected strictures (eg, Crohn disease), and complications from prior GI surgery that may affect mobility and transit.
Concurrent drug therapy issues:
• Altered medication absorption: May affect absorption of other medications; monitor for safety and effectiveness. Avoid concurrent administration when possible. For oral medications scheduled to be administered at lunch or dinner, the manufacturer's labeling recommends administering the concomitant medication after the meal has started.
Dosage form specific issues:
• Packaging: Do not use if blister package is damaged or capsules are broken, crushed, or damaged.
• Appropriate use: Should be taken under supervision of a health care provider as part of a structured weight loss program. Not a food substitute.

An increased risk of adverse maternal and fetal outcomes is associated with obesity. However, moderate weight gain based on prepregnancy BMI is required for positive fetal outcomes. Therefore, medications for weight loss therapy are not recommended at conception or during pregnancy (ACOG 156 2015; Stang 2016). Use of this product is contraindicated in pregnant females.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience bloating, abdominal pain, diarrhea, constipation, flatulence, nausea, rhinitis, pharyngitis, or headache. Have patient report immediately to prescriber signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, tachycardia, confusion, increased hunger, or sweating) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
