Who should not take Ovestin
A contraindication is a condition under which Ovestin (Estriol) should not be taken because the risk outweighs the benefit. Ovestin has both absolute contraindications (do not use) and relative cautions (use only after careful review). This page summarises both at the 0.1%, 0.5mg, 1mg, 2mg dosing range.
Absolute contraindications
According to the prescribing information for Estriol, absolute contraindications typically include severe allergic reactions to the active ingredient or excipients, severe hepatic or renal impairment, certain cardiovascular conditions, and concurrent use of specific interacting medications. The exact list depends on the molecule and is detailed in the official label.
Relative cautions
Relative cautions are situations where Ovestin can be used but with extra monitoring, dose reduction or alternative considered. These often include mild-to-moderate organ impairment, age extremes, multiple comorbidities, and complex medication regimens. Estriol in Ovestin binds estrogen receptors with shorter receptor occupancy than estradiol, producing a 'weak' estrogenic effect.
