The SCHWARZ PHARMA Family of PEG Lavage Products

The SCHWARZ PHARMA family of PEG lavage products for colonoscopy preparation is designed to make your colonoscopy as clear and easy as possible. We offer patients undergoing a colonoscopy the flexibility of choosing from different products featuring different ingredients, consistencies and flavors.

TriLyte with flavor packs has less salt than our original PEG lavage, Colyte with flavor packs. Colyte with flavor packs has a slightly different consistency than TriLyte with flavor packs. Both PEG lavages are supplied in a 4-liter bottle and are available with the following flavor packs: Lemon Lime, Orange, Pineapple, Cherry and Citrus Berry.

Ask your healthcare professional to recommend the PEG lavage that’s right for you.

As with all polyethylene glycol (PEG) lavages, nausea, abdominal fullness, and bloating are the most common adverse reactions, occurring in up to 50% of patients. Oral medication administered within 1 hour of the start of administration of Colyte with flavor packs or TriLyte with flavor packs may be flushed from the gastrointestinal tract and not absorbed.

Ask your healthcare professional whether Colyte with flavor packs or TriLyte with flavor packs is right for you.
