Rarely, pancreatitis, erythema multiforme, toxic epidermal necrolysis, corneal membrane sloughing, ocular ischemia, or ocular haemorrhage.
Pregnancy & Lactation
Pregnancy category D. There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).

Embryo-fetal Toxicity: Gefitinib can cause fetal harm. Potential risk of Gefitinib to a fetus should be advised and effective contraception should be used.
Use in Special Populations
Pediatric Use: The safety and effectiveness of Gefitinib in pediatric patients have not been established.
Geriatric Use: No overall differences in safety were observed between patients 65 years and older and those younger than 65 years. There is insufficient information to assess for differences in efficacy between older and younger patients.
