I am on flomax for an enlarged prostate . I
See below, please
Hello, I'm Dr. Branch,
Thanks for using Ask a Doctor.
Flomax does often have side effects, usually lightheadedness from low blood pressure when standing. However, from what I know it does not have a significant association with diabetes or cancer. Cialis is a medication for ED, so the two medications are for two different conditions, and Cialis will not help with your prostate. Cialis can lower blood pressure and can affect the heart, so if you have any unstable heart disease, you should wait until it is stable and your doctor approves it before starting it. Also, both Cialis and Flomax lower the blood pressure, so you shouldn't take both at the same time.
As for other options for your prostate, there are other medications like Flomax, such as terazosin, doxazosin, etc. If you are trying to avoid medications like Flomax, there is another kind of medication used for prostate, such as finasteride or dutasteride, which may be a better option if you plan to use Cialis.
I hope that is helpful...
Please let me know if you have any questions about any of that and I would be glad to discuss it with you further.
