Frequently Asked Questions About Loqtorzi Side Effects

How Do Loqtorzi Side Effects Compare to Those of Xeloda?

Both Loqtorzi and Xeloda are treatments for nasopharyngeal cancer but differ in their mechanisms and side effect profiles. Common mild side effects like nausea, fatigue, and muscle pain may overlap. However, Loqtorzi, as an immunotherapy, can trigger immune-related adverse effects affecting various organs, whereas Xeloda, a chemotherapy drug, may cause issues such as hand-foot syndrome and blood cell abnormalities.

Can Loqtorzi Cause Long-Term Side Effects?

Yes, some patients may experience long-lasting side effects due to immune system activation, including pneumonitis, hepatitis, hormonal disorders, and thyroid dysfunction. These effects may arise during or after treatment completion. Discuss potential long-term risks with your healthcare provider.

Understanding Specific Side Effects

Pneumonitis

An uncommon but serious lung inflammation that may cause cough, shortness of breath, and chest pain. Individuals with prior chest radiation have increased risk. Early medical intervention is crucial.

Thyroid Issues

Thyroid dysfunction is relatively common, with hypothyroidism presenting as fatigue, weight gain, and dry skin, while hyperthyroidism may cause rapid heartbeat, irritability, and weight loss. Treatment adjustments and hormone therapies can manage these conditions effectively.

Allergic Reactions

Tracking Side Effects: Keeping a detailed log of your symptoms, their onset, severity, and impact on daily life can help your medical team optimize your treatment plan.
