What side effects does Truseltiq (infigratinib) have?
Truseltiq is the brand name for infigratinib, an oral medicine used to treat certain cancers with FGFR2 alterations. Reported side effects include both common effects and more serious reactions that require prompt medical attention.
Commonly reported side effects include fatigue, nausea, diarrhea, decreased appetite, dry mouth, constipation, abdominal pain, and vomiting. Changes in lab tests can also occur, such as elevated liver enzymes and phosphate level abnormalities.
More serious side effects can include liver injury, worsening vision problems, and effects related to phosphate levels (such as hyperphosphatemia). Some patients may also experience serious gastrointestinal toxicity or complications that require dose modification or treatment interruption.
When do side effects show up, and what should patients watch for?
Many side effects appear during the first weeks of treatment, especially gastrointestinal symptoms (like nausea, diarrhea, and vomiting) and fatigue. Lab-related abnormalities may also be detected early through routine bloodwork.
Patients are typically told to monitor for warning signs that could indicate severe toxicity, including symptoms of liver problems (for example, yellowing of the skin or eyes, dark urine, severe fatigue), significant worsening gastrointestinal symptoms (persistent or severe diarrhea/vomiting), and eye/vision changes.
Are there specific risks related to eye or liver problems?
Yes. Truseltiq can cause clinically significant risks involving the liver and can also lead to eye-related events in some patients. If vision changes occur or if liver-related symptoms develop, clinicians may adjust dosing or stop treatment depending on severity.
What should you do if side effects are severe?
Clinicians often manage Truseltiq side effects with supportive care and dose adjustments. If side effects are severe (or persist despite supportive treatment), the usual approach is interruption, dose reduction, or discontinuation based on the severity grade and clinical judgment.
