Use of anti-Parkinson medication during pregnancy: a case series

Abstract

Introduction

Experience about the use and safety of anti-Parkinson (anti-PD) medication during pregnancy is scarce.

Methods

We have retrospectively evaluated the course and outcome of pregnancy in PD patients who used anti-PD medication during their pregnancy.

Results

14 PD patients who used anti-PD medication during part or whole of their pregnancy were included. Dopamine agonists were used in 13 patients, levodopa/benserazide in 4, levodopa/carbidopa/entacapone in 1, rasagiline in 7, amantadine in 4, and biperiden in 1 patient. Nine patients were on combination treatment at the time of their pregnancy. During their whole pregnancy, dopamine agonists had been used in six patients, levodopa in four, and rasagiline in one. Four patients experienced adverse outcomes: one had spontaneous abortion while receiving pramipexole, one elderly mother gave birth to a child with Down syndrome, while receiving pramipexole and rasagiline, in one case, there was fetal distress under levodopa/benserazide, piribedil, and rasagiline which resolved spontaneously, in one case, one of the twins did not survive after the birth while the mother was receiving pramipexole and rasagiline. In none of these cases an association with the use of anti-PD medication and adverse outcomes was clearly established. In one patient, motor symptoms worsened despite high dose levodopa, four others experienced transient worsening upon dose reduction.

Conclusion

Results in our case series suggest that levodopa, rasagiline, pramipexole, and ropinirole alone or in combination with each other may be considered relatively safe during pregnancy. Expected benefits and risks should be considered when prescribing anti-PD medication in pregnant women.
