A comparative study of the safety, effectiveness and acceptability of two foaming vaginal tablets (nonoxynol-9 versus menfegol) in Thai women.
Two foaming vaginal tablets containing nonoxynol-9 (OVT-n) or menfegol (OVT-m) were studied to evaluate safety, effectiveness and acceptability. The study was conducted at the Chulalongkorn University, Institute of Health Research, Bangkok, Thailand. One-hundred-two women randomly assigned to one of the two types of tablets were scheduled for follow-up visits at 1, 3, 6 and 12 months. Although there were differences between the two groups in the gross cumulative 12-month life table rates and 12-month continuation rates, these differences were not statistically significant. Twelve-month discontinuation rates for accidental pregnancy were 31.7 per 100 women for OVT-n group and 25.3 per 100 women for the OVT-m group. Seventeen of the total 22 pregnancies occurred due to use failure. This study indicates that the regular and proper use of OVT-n or OVT-m tablets are comparable and are a safe means of birth control. Although a few product-related (burning) or medical complaints were reported by both groups of tablet users, it seems that the vaginal contraceptive is an acceptable method for fertility control in a suitable population who will use it regularly and properly.
