The use of benzodiazepines is not negligible in pregnant woman and self-medication is considerable. To investigate the effects on the fetus of benzodiazepines used during pregnancy, we reviewed animal and clinical studies completed with observations of CRPV (Centres Régionaux de Pharmacovigilance). Pooled results indicate that the risk of malformations associated with first-trimester exposure to benzodiazepines remains small. However, in a fetus exposed essentially to long-acting benzodiazepines on a long-term basis, neonatal hypotonicity, failure to feed and/or withdrawal syndrom could be observed.

Since 1996, marketing of new drugs called protease inhibitors has revolutionized the treatment of patients suffering from AIDS. The side-effects of this new therapeutic family are quite well known but we wanted to evaluate the attitude of the clinician: can these adverse effects be corrected by symptomatic treatment, do they regress spontaneously or do they lead to an alternative PI therapy? We therefore carried out a retrospective survey in the Infectious Diseases Department of Poitiers Hospital consisting in research on files of patients (n = 70) treated in this department (hospitalization and consultation) for any clinical or biological abnormality attributable to the PI. For each drug we determined what sort of side-effects could be found and the position adopted by the clinician. For 30 patients the PI was stopped and for 21 of these cases because of drug toxicity (gastrointestinal, neurological, renal and metabolic effects). The biological anomalies are quite well tolerated and regress spontaneously in most cases.
