Please tell me, could cialis be used for woman also!?

Yes, although ...: Theoretically, its mechanism to work in the penis for erection would have no difference in working in female clitoral erection, but not necessarily to enhance sexual arousal which is mainly related with sex drive, in time leading to physical erection for men and women. So, may try (off-label use) preferably under professional supervision, while the mood for sex is right.
