6.2 Postmarketing Experience The following adverse events have been reported during post-approval use of KISQALI.
Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Respiratory disorders: Interstitial lung disease/pneumonitis Skin and subcutaneous tissue disorders: Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug-induced hypersensitivity syndrome (DiHS)/drug reaction with eosinophilia, and systemic symptoms (DRESS).
