A prescriber determines the appropriate regimen based on the indication, laboratory results, organ function, interactions and adverse effects.

The product’s official safety labeling governs specific requirements.

Possible Side Effects

The adverse-effect profile of Lorlatinib varies by indication and combination regimen.

Drug Interactions

Prescription medicines, over-the-counter products, herbal supplements and certain foods can change the effectiveness or safety of Lorlatinib.
