When checking interaction based on authoritative sources Drugs.com, Rxlist.com, Webmd.com, Medscape.com there are contraindications or side effects that may cause harm or increase the negative effect from drug interaction with food or lifestyle.

Consumer:

Food may reduce the absorption of methylnaltrexone when taken orally, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take oral preparations of methylnaltrexone on an empty stomach at least 30 minutes before your first meal of the day.

Professional:

ADJUST DOSING INTERVAL: Food may reduce the rate and extent of absorption of methylnaltrexone following oral administration. When a single 450 mg oral dose of methylnaltrexone was administered with a high-fat breakfast (approximately 800 to 1000 calories; 60% from fat, 25% from carbohydrate, and 15% from protein) in healthy study subjects, methylnaltrexone peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 60% and 43%, respectively, while time to reach Cmax delayed by 2 hours.

MANAGEMENT: Oral methylnaltrexone should be taken with water on an empty stomach at least 30 minutes before the first meal of the day.
