Creon - am I taking too much or too little?

Posted by stillaround @stillaround, Sep 27, 2025

Hi - pancreatic cancer person here. (Surgery 14 years ago removed tail, recurrence on head a year ago, currently in remission after treatment including hi-dose radiation.) Started Creon several weeks ago. I THINK I am taking enough as I am finally putting weight on, stools are proper color etc. But I am quite bloated with distended belly and a bit constipated. If everything else is good could this mean I'm not taking enough? Or does constipation with normal stools mean I'm already taking too much?

I take 36,000 with my smallish calorie-dense meals, my weight is 108. The PERT calculator indicates I need closer to 48,000 at breakfast but other meals I'm in range.

Recently prescribed Creon. I am 66 female weight 195 - nearly impossible for me to lose belly fat. Struggling with how much & when to take Creon
Anyone else have similar reason for being prescribed Creon and what the correct dosage should be?

@allioops Optimization of Creon is easily accomplished using the dosing calculator at pertcalculator.org. The site also has information on taking the first capsule at the beginning of the meal and staggering capsules throughout the meal when additional capsules are required.

Have you checked with the prescribing physician or his medical team yet

My surgeon sent the prescription to creon. I take 2 large capsules at meals and 1 capsure at snack. If I don't take the creon at a snack my stool is clay colored. And I lose weight.

Hello! I take Qty. (2) 12,000 Units with my dinner only. My breakfasts and lunches tend to be small and lower in fat. My dinner is my largest meal and the one that can have more fat although I try to stay with fish, chicken, and turkey most of the time.
If I have a higher fat meal, I can tell that Qty. (2) is probably not enough and could benefit and take an additional Creon as I become bloated and gassy. Otherwise, I go by how I feel (gassy or not) and the look and frequency of my stools. Prior to starting on Creon, I has very, very gassy, bloated, and very soft stools. My weight has been holding steady at 168 to 140 lbs.

I have been on Creon for nine years, and I still need to make frequent adjustments to the dose because it depends on what you eat.

My initial prescription was for three 24,000 capsules units at each meal, but I usually take one capsule. You know you didn't take enough when you get steatorrhea (loose stools, etc.) because of malabsorption of the fats you consume.

A few months ago I read an article in a national newspaper written by an endocrinologist: she advocates, and takes herself, psyllium multiple times a day. I think it helps, but apparently it can worsen pancreatic enzyme insufficiency. We are all different and trial and error seems inevitable with Creon.

@hopeful33250 Thanks, I will look there. Was referring to recovery from high dose radiation which I had last spring. Even though I am currently in remission with low CA19 I've been having some stomach pain.

@stillaround I had 15 sessions of IMRT in Aug. Intensity modulated radiation therapy. I was warned beforehand by the rad. oncologist that I may experience some stomach discomfort. I did and it was considerable. He told me after the pain started at approx. 8 sessions, that the reason the pain was occurring was that the rad. beam had to be brought very close to my stomach in order to hit the pancreatic tumor. There were 2: pancreas and liver. Now, in Oct., the stomach pain has faded considerably and he called it "inflammation". I won't have the results of the PET scan and MRI until late next week and am hoping/praying for the best. Have patience @stillaround. I think your stomach pain will dissipate over time.

Do your doctors think that the stomach pain is related to the radiation treatment?

Thanks for the welcome and information. A week later and lowering the amount of Creon seems to be helping. Radiation-induced gastric injury or fibrosis may be causing accompanying stomach pain. Recovery is definitely a full time job.
