Gonadotropin-releasing hormone (Gn-RH) agonists and antagonists.  These drugs block the production of ovarian-stimulating hormones, lowering estrogen levels and preventing menstruation. This causes endometrial tissue to shrink. Because these drugs create an artificial menopause, taking a low dose of estrogen or progestin along with Gn-RH agonists and antagonists may decrease menopausal side effects, such as hot flashes, vaginal dryness and bone loss. Your periods and the ability to get pregnant return when you stop taking the medication.

1. Loosen the flaring bar.
2. Cut the tube and remove any burrs.
3. Insert the tubing into the proper sized hole. The tubing should extend a distance equal to the width of the shoulder on the corresponding adapter.
4. Tighten the wing nut: first – closest to the tube, then another one.
5. Grease the adapter and insert into the tubing. Make sure the adapter is straight. Slightly turn the yoke to lock into place. Secure this locked position with thumb and forefinger.
6. Screw down one flaring cone until it engages with the adapter.
7. Slightly back off the flaring cone and remove the adapter. Screw the cone down tightly onto the tubing. This procedure forms a 45° double flare, folding the tubing back on itself.
