Like all other anticancer medication, 5 Flucel 250mg Injection can cause side effects. Common side effects are nausea, vomiting, diarrhea, mouth sores, hair loss, and an increased risk of infection. However, not all patients will experience these side effects, and the severity of the side effects can vary from person to person. No specific foods need to be avoided when receiving 5 Flucel 250mg Injection, but alcohol, spicy or acidic foods, citrus fruits and juices, and high-fiber foods may worsen some of the side gastrointestinal symptoms. Patients should consider avoiding or limiting these foods during treatment. Inform your physician before starting this treatment if you have undergone surgery in the last 30 days or are following a controlled sodium diet.
