This topic is about managing constipation after receiving a Keytruda infusion, especially for someone with a colostomy. If you're in a similar situation, here are some friendly tips and suggestions that might help:

1. Fruit Juices: Try drinking small amounts of prune juice, about a quarter to half a glass, as it can help stimulate bowel movements. Grape juice is another option, but be cautious with the quantity as too much might be overly effective.

2. General Diet Measures:
- Increase your intake of dietary fiber, focusing on whole fruits, which can help soften stools.
- Stay well-hydrated by drinking plenty of water.
- Consider reducing your caffeine intake, as it can sometimes contribute to dehydration.

3. Osmotic Laxatives:
- Milk of Magnesia: Some people find it helpful to take a full dose-cup the night before changing their appliance for a thorough emptying. On other nights, a smaller dose of a quarter to half a cup can help maintain regular output.
- Miralax (polyethylene glycol 3350): This is another option that gently draws water into the colon, and some have found it effective when recommended by their doctor.
