Thanks very much.
Many drugs have the potential of causing hair loss.
In clinical trials, patients taking Premarin have reported loss of scalp hair and a few case reports of hair loss while taking Provera have been reported. Hair loss is considered to be an infrequent side effect of the medications your mother is taking, but individual patients may react differently. It would be difficult to state whether or not your mother's hair loss is due to the combination of these medications or to her medical condition. As with all medications , the benefits received from treatment may outweigh the risks associated with the side effects. Unfortunately, these side effects can not be eliminated.
