Objective:
To describe the use of alternative drugs during pregnancy.
Design:
A trial including 3 surveys on drug use during pregnancy in maternity centers in one area of Finland in 1985-86 (study 1), and a retrospective survey in 2 maternity hospitals in Finland in 1988 (study 2).
Patients And Methods:
Study 1: 2912 pregnant women (about 94% of pregnant women in the area during the study period); 97-88% returned questionnaires. Study 2: 180 out of 181 consecutive women giving birth. In study 1, drug use (including drug-like products) in the last two weeks was asked by questionnaires around 12th, 28th, and 36th gestation weeks. In study 2, women were interviewed 2-3 days after birth asking about any drugs used during pregnancy. Due to the method of asking, our studies underestimate the level of using alternative drugs.
Results:
In study 1, a total of 97 (3.6%) pregnant women reported use of alternative drugs. Most drugs were dietary supplements, and by current knowledge harmless. But a few women had used (potentially) dangerous drugs. The users were from the higher social class and they had also used pharmaceutical specialties more often than non-users. In study 2, 14% had used alternative drugs at some time during pregnancy.
Conclusion:
Because our surveys showed that alternative drugs are used, possibly with increasing frequency, during pregnancy, further studies on safety are needed.
