What is Prescribing information?
The FDA package insert formatted in easy-to-find categories for health professionals and clinicians.
CoLyte FDA Prescribing Information: Side Effects
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice.
Nausea, abdominal fullness and bloating are the most common adverse reactions (occurring in up to 50% of patients) to administration of Colyte. Abdominal cramps, vomiting and anal irritation occur less frequently. These adverse reactions are transient and usually subside rapidly. Isolated cases of urticaria, rhinorrhea, dermatitis, and rarely anaphylaxis, angioedema, tongue edema, and face edema have been reported which may represent allergic reactions.
To report suspected adverse events contact Meda Pharmaceuticals Inc. at toll free 1-888-317-0001 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
