Controlled studies on differences between men and women regarding the effect, safety and pharmacokinetics of phenoxymethylpenicillin are lacking. A smaller study indicates that exposure of phenoxymethylpenicillin during pregnancy can be lower than in non-pregnant women, and dose adjustment thus can be needed.

Additional information

Pharmacokinetics and dosing

A pharmacokinetic study described changes in phenoxymethylpenicillin pharmacokinetics during pregnancy (12 pregnant women, 6 non-pregnant controls), in comparison to non-pregnancy. Following a single dose, half-life was shorter during the third trimester compared to the non-pregnant state. Also, exposure was lower for women in the second trimester of pregnancy than for non-pregnant women. These findings indicate increased elimination of phenoxymethylpenicillin during mid and late pregnancy, although differences in elimination were non-significant. The authors recommend reduced dosing-interval or increased dose of phenoxymethylpenicillin in pregnant women [1].


No studies with a clinically relevant sex analysis regarding the effect of phenoxymethylpenicillin have been found.
