1200 mg Lithium, .075 Xanax, and 25 mg Mellaril. It's causing me to feel quite ill at ease. During the last 2 months I have been having symptoms of PMS but no period. The Gynecologist has recommended Provera, but I don't feel comfortable taking any more medication. Lithium is not known to cause endocrinologic problems except for hypothyroidism.
Hypothyroidism is a potential cause of a decreased period.
Have your physician check your thyroid levels. Xanax should have no effect. Mellaril is also a potential cause of amennorhea. About the only way to test mellaril is to stop the drug for several weeks, which is something you may not be able to do. Back to Drug InfoNet Home Page.
