Treatment options for perimenopause? Thanks!

Many options. Birth control hormone methods, low dose hormone replacement therapy, over the counter Progesterone creams, and various herbal products can help with the symptoms. Best to discuss the options with your physician to see what would work best for you.
Several. Rx options are based primarily on the patient's symptoms such as "hot flashes", vaginal dryness, inability to concentrate, insomnia, etc. Hormone replacement therapy, clonidine, an anti-depressants all have a place in treatment. Some women do not require any forms of treatment if they are asymptomatic.
