How Quinacrine Antibiotic Works as a Contraceptive
When placed in the fallopian tubes, the quiancrine antibiotic causes the fallopian tubes to close off. This makes it impossible for an egg to pass through.
The QS procedure is non-surgical. To insert the pellets of quinacrine antibiotic into the patient's uterus, a doctor, nurse, or midwife uses a modified IUD inserter. The result permanently diables a woman's ability to become pregnant.
