Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of Creon®, Pancreaze®, Pertzye®, and Zenpep® in children.
Appropriate studies have not been performed on the relationship of age to the effects of Ultresa™ in children younger than 12 months of age, and Viokace™ in children. Safety and efficacy have not been established in these age groups.
No information is available on the relationship of age to the effects of Creon®, Pancreaze®, and Pertzye® in geriatric patients.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Ultresa™, Viokace™, and Zenpep® in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving these medicines.

Take this medicine exactly as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. To do so may increase the chance of side effects.
This medicine comes with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor about anything you do not understand.
Take this medicine with meals or snacks and enough liquid to swallow it completely, unless otherwise directed by your doctor.
When prescribing this medicine for your condition, your doctor may also prescribe a personal diet for you. Follow the special diet carefully. This is necessary for the medicine to work properly. It is also important to drink plenty of water while you are on this medicine.
For patients taking the tablets:
- Viokace™ tablet is used in combination with certain medicines for stomach ulcer called proton pump inhibitors (eg, esomeprazole, lansoprazole, omeprazole, Nexium®, Prevacid®, Prilosec®).
- Swallow the tablets quickly with some liquid, without chewing, to avoid mouth irritation.
For patients taking the delayed-release capsules:
- Swallow the capsule whole.

- When given to adults or children who can not swallow the capsule, the capsule may be opened and sprinkled on a small amount (about 10 mL or less) of soft food with a pH of 4.5 or less that can be swallowed without chewing, such as applesauce. This mixture must be swallowed immediately and followed with a glass of water or juice. This will ensure complete swallowing of the contents of the capsule and avoid mouth irritation.

Do not mix the contents of the capsule directly to alkaline foods, such as milk, breast milk, formula, or ice cream. This could reduce the effect of the medicine.
