Patients undergoing chemotherapy can take FPP® before and after their treatment, but not during the treatment. You can use FPP® as a supplement by taking 2 sachets a day for 2 weeks before starting your treatment. Do not take FPP® during chemotherapy. After the end of chemotherapy, you can use FPP®. We recommend taking 3 sachets daily the first week after chemotherapy, 2 sachets per day the second week, and from the third week you can continue to take 1 sachet per day. If you have difficulty swallowing and a lack of saliva, dissolve FPP® in a little water. FPP® is not intended to treat or prevent any disease.
