A 22-year experience with quinacrine sterilization in a rural private clinic in Midnapore, India: a report on 5 protocols and 1838 cases.

OBJECTIVES: Evaluate the safety and effectiveness of quinacrine for non-surgical female sterilization in five different protocols.
METHODS: The 5 trials were conducted sequentially. The first and largest, with 985 cases, tested the use of a curved inserter to place a 50 mg dose of quinacrine near each tubal ostia. The next 3 trials were carried out to determine the effect of adjunct procedures on the efficacy of the standard recommended protocol. The three adjuncts were 75 mg of intrauterine diclofenac, 10 mg medroxyprogesterone IM and either 10 mg of atropine IM or 20 mg of hyoscine butylbromide IM The final trial focused on the currently recommended protocol.
RESULTS: The 100 mg dose placed at the tubal ostia with the curved inserter resulted in a failure rate of 9.0% at 20 years. Diclofenac or medroxyprogesterone did not improve efficacy over quinacrine alone. Atropine or hyoscine butylbromide substantially diminished the effectiveness of the quinacrine. The failure rate with the standard protocol in our series of 122 cases was 0.8% at 3.5 years. Side effects were minor. There were no deaths nor serious complications with any of these protocols. DISCUSSION: All 5 protocols appeared to be safe and the standard one was the most effective.
