What side effects does Alunbrig (brigatinib) have?
Alunbrig’s most notable side effects come from how brigatinib affects both healthy tissues and cancer cells. Commonly reported effects include gastrointestinal symptoms and issues related to breathing and blood chemistry, along with skin and fatigue-related complaints.
What are the most common Alunbrig side effects?
Patients and clinicians most often report:
- Nausea, vomiting, diarrhea, or constipation
- Fatigue
- Cough or shortness of breath
- Increased liver enzymes (signs of liver irritation on lab tests)
- Rash
What breathing-related risks should patients watch for?
Alunbrig can cause serious lung problems in some patients. This is one of the key safety issues people search about, especially early in treatment. If you develop new or worsening shortness of breath, cough, or breathing difficulty, you should seek medical advice promptly.
What liver and blood-test abnormalities can happen?
Brigatinib can raise liver enzymes, which may indicate liver irritation. It can also cause changes seen on bloodwork that clinicians monitor during treatment, such as laboratory abnormalities that may require dose adjustment or interruption.
What serious side effects are people most concerned about?
Serious adverse reactions can include:
- Significant lung (respiratory) problems
- Severe liver problems (clinically meaningful enzyme elevations)
- Other potentially serious reactions that require urgent evaluation
Because severity and timing vary by patient, doctors typically monitor closely, especially during the first phase of therapy.
When do side effects usually start?
Some side effects can appear soon after beginning treatment, while others build over time. Lung and respiratory symptoms are particularly important to monitor early, since they can develop in the initial treatment period.
What should patients do if they get side effects?
Side effects often lead to dose changes, treatment interruption, or supportive care depending on how severe they are. Contact the prescribing clinician quickly for new, worsening, or severe symptoms—especially breathing problems.

If you want, tell me whether you’re asking about side effects for newly starting Alunbrig versus someone already on treatment, and I can narrow the answer to what’s most relevant to that timeframe.
