Can Imfinzi cause dry mouth and changes in how food tastes?
Yes, immunotherapy drugs like Imfinzi can cause both dry mouth and taste changes. These are recognized side effects of lung cancer immunotherapy treatments.
Taste changes, called dysgeusia, are relatively common with cancer treatments. You might experience metallic tastes, sweet tastes, or find that foods just don't taste right anymore. Some people describe everything tasting like pennies or cardboard.
Dry mouth often goes hand-in-hand with these taste changes and can make eating and drinking even more challenging.
Here are some ways to manage these side effects:
- Try ice pops made with 100% fruit juice to help with dry mouth and get some nutrition
- Keep water very cold and sip frequently throughout the day
- Experiment with smoothies or protein shakes - keeping them cold and foamy can make them more tolerable
- Focus on the foods that still taste okay to you, even if your diet becomes limited for a while
- Consider working with a dietitian at your oncologist's office who can suggest high-calorie options and flavor combinations
A MyLungCancerTeam member shared that when nothing tasted right, really cold Ensure shakes (foamy and in a glass) helped them maintain nutrition.
Let your oncology team know about these symptoms - they can offer additional suggestions to help maintain your nutrition and comfort during treatment.
