Side Effects

Adverse events associated with letrozole are generally mild to moderate and rarely severe enough to require discontinuation. Many can be attributed to either the underlying disease or the normal pharmacological open consequence of ostrogen deprivation (hot flushes, hair thinning). The most frequently reported adverse events are musculoskeletal pain, arthralgia, headache, fatigue, nausea, dyspnoea, peripheral edema, coughing. constipation, vomiting, chest pain, viral infection, diarrhoea rash, abdominal pain, dyspepsia and anorexia, Dizziness, weight increase and pruritus are less commonly seen.

Drug Interaction

Clinical interaction studies with cimetidine and warfarin indicated that the co-administration of letrozole with these drugs does not result in clinically significant drug interactions, even though cimetidine is a known inhibitor of one of the cytochrome P450 isoenzymes capable of metabolizing letrozole in vitro.
