Pregnancy outcomes after maternal use of thiocolchicoside: A case series.

OBJECTIVE: The 2014 report by European Medicines Agency (EMA) restricted the use of thiocolchicoside for all reproductive-age women. In this study, we aim to expand the systematically-collected human data and discuss it within the frame provided by this report. METHODS: We identified and evaluated the outcomes of 48 prospectively recorded pregnancies referred to Terafar (Teratology Information Service, Izmir, Turkey). RESULTS: Of 42 pregnancies with first-trimester exposure and known outcomes, 31 resulted in live births, four in miscarriage and seven ended with elective terminations. There were 26 normal outcomes, two major and three minor congenital malformations among the live births. CONCLUSIONS: Despite a number of limitations, our results and previous case series collectively strengthen the view that thiocolchicoside is unlikely to be a major teratogen. EMA's 2014 report should be revised to reflect this finding, while current restrictions on use should continue until more detailed safety information is available.

Pregnancy outcomes after maternal betahistine exposure: A case series.

OBJECTIVE: To investigate the pregnancy outcomes of women who were exposed to betahistine during their pregnancies. METHODS: We identified and evaluated the outcomes of 27 pregnant women who were referred to Terafar (Teratology Information Service, Izmir, Turkey) for a teratological risk assessment. RESULTS: Of 24 pregnancies with known outcomes, 21 resulted in live births (including two pairs of twins) whereas two ended with miscarriage and three with elective terminations. Among the 20 live births for whom the malformation details were available, there were 17 normal outcomes, one major and two minor congenital malformations. CONCLUSIONS: Despite a number of limitations, this case series may be of value regarding counseling pregnant women with inadvertent betahistine exposure. Further epidemiological studies with larger sample sizes and control groups are necessary to draw more definite conclusions.

Counselling pregnant women at the crossroads of Europe and Asia: effect of Teratology Information Service in Turkey.

Background Previous studies from western countries demonstrated the effectiveness of Teratology Information Service (TIS) counselling in reducing the teratogenic risk perception of pregnant women. Objective To assess whether TIS counselling would be effective in reducing the teratogenic risk perception of the Turkish pregnant women. Setting A TIS (Terafar) operating in a university hospital in Turkey. Methods A cross-sectional survey study. Pregnant women with non-teratogenic medication exposures were asked to assign scores on visual analogue scales (VAS) in response to the questions aiming to measure their teratogenic risk perception. The mean score before and after counselling were compared and the associations with maternal socio-demographic characteristics were analysed using SPSS (Version 20.0). Main outcome measures The differences in the mean scores of the perception regarding the baseline risk of pregnancy, own teratogenic risk and the likelihood of termination of pregnancy before and after counselling and their possible associations with maternal socio-demographic characteristics. Results 102 pregnant women participated in the study. The counselling significantly reduced the mean own teratogenic risk perception score and the mean score for the likelihood of termination of pregnancy whereas the mean baseline risk perception score was not significantly changed. Pregnancy week <8 and the exposed number of active ingredients <3 were significantly associated with the difference in the mean score for the likelihood of termination of pregnancy. Conclusions TIS counselling lowers the teratogenic risk perception of Turkish pregnant women and increases their likelihood to continue the pregnancy as it does in the western countries.
