Progesterone is a female hormone important for ovulation and menstruation. Progesterone causes changes in the lining of your uterus, making it easier for a fertilized egg to attach to the uterus at the beginning of pregnancy. Progesterone then helps your body maintain the pregnancy.

Crinone (for use in the vagina) is used to cause menstrual periods in women who have not yet reached menopause but are not having periods due to a lack of progesterone in the body.

Crinone is also used in fertility treatment as part of Assisted Reproductive Technology (ART) for women unable to get pregnant due to a lack of natural progesterone in the body.

Crinone is also used to prevent overgrowth in the lining of the uterus in postmenopausal women who are receiving estrogen hormone replacement therapy.

Crinone may also be used for purposes not listed in this medication guide.

• Generic Name: omeprazole / sodium bicarbonate
• Dosage Forms: capsule; powder, for suspension

Zegerid contains a combination of omeprazole and sodium bicarbonate. Omeprazole is a proton pump inhibitor that decreases the amount of acid your stomach produces. Sodium bicarbonate is an antacid that raises the pH in your stomach to keep the omeprazole from breaking down in stomach acid.

Zegerid is used to treat heartburn and other symptoms of gastroesophageal reflux disease (GERD).

Zegerid is also used to treat certain type of ulcers, or to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).

Zegerid is not for immediate relief of heartburn symptoms.
