My Urologist has recently told me to take cialis 5mg once a day every day. He also said to continue using 100 mg of viagra before sex only. Does anyone know if this is unusual or dangerous??
When I told my primary care doctor, he kind of frowned on mixing the two, but my Urologist, (a ED EXPERT)said the primary care doctor did not know what he was talking about.

Anyone considering Viagra use should be aware that the high doses often prescribed often cause problems for some men, so exercise caution. 
To start with, use a lower size like 25, or if you have 100 size pills, cut them into smaller sizes to ensure they are well tolerated.

Following prostatectomy, it is normal procedure to prescribe Cialis, either 5mg daily or 10mg every two days in order to promote healing by maintaining a good blood supply to regenerating tissue. (Cialis tends to be longer acting than either Viagra or Levitra). When the time for sexual activity comes then obviously your doc feels the normal dose of Viagra (which is 100mg per tab) is required to be effective for sexual activity. You would have to assume that a specialist in ED would be aware of any prospective problems. You could always forgo the 1/4 dose Cialis the day after taking 100mg Viagra.

My doc told me to take a 25m of Viagara daily and then Cialis twice a week and to just skip the Viagara on the Cialis days. I too am a little concerned about the meds. I use the pump 3 times a week. Can anyone give me there opinion as to whether I am on the right track here to get my ED under control? I considered doing some experimenting and taking a "V" daily and just skip the Cialis, to see if that will get a different reaction.  I also "think" I read here where some of you had no luck with a specific ED med and another one did the trick?  I have not had an erection(without the pump, and I have a difficult time constricting myself for sex, just creeps me out, but I will if I have to).  I have just used the pump to help keep the vessels open.
This is frustrating.

" then obviously your doc feels the normal dose of Viagra (which is 100mg per tab) is required to be effective for sexual activity."

As I tried to explain earlier, be aware that although some might think that a "normal" dose of Viagra is 100mg, that  dose of Viagra can AND OFTEN DOES cause  problems for some men.

What's more, 100 size is not necessarily required for sexual activity.

Causes problems? Are you just refering to erectile issues, like having the opposite effect  or other kinds of problems?

Sam Benton (Larry), I have been pumping daily for 16 months, taking 50 mgs generic Viagra daily for the first 10 months, then the same 3 times a week until recently switching to 20mg Leverta 3 times a week.  ED recovery can be a long process with little visible results for months, or even longer.  The point is consider the pump and pills as rehab therapy, not as a tool for erections, until such time as you begin to repair, renew or regrow those erectile nerves. It may be weeks, it may be months, it may be up to 2 years or beyond.  Keep up the pumping, that will really help in the long run.  I personally feel that a man who is rehabbing erectile function should be taking some kind of ED pill regularly to keep tissue infusion going in the penis, abdomen and such.  What you settle on is a personal decision made with your doctors help.  Penile injections have been shown in a couple studies to accelerate regrowth and renewal, it is claimed even more so that the pump and pills.  Now that's a personal choice... tongue

Sam "


Problems I have become aware of  of include severe head aches, distorted vision and loss of balance. 

In one case medical assistance was required: this instance could have been related to the person also using  another medication, but in others it seemed to be simply that Viagra was not tolerated well, &/or too large a dose was used.

It does seem that it could be potentially dangerous in some circumstances if someone did not tolerate a large dose well, or if they had a medical condition they might or not be aware of.

Obviously not every person will have any kind of  problem, but it does seem prudent to start with a small dose, say a 25 size to start with.

Generic Viagara? Didn't know it was out there. I will ask for it next time. If the pump creeps me out, you know the thought of those injections send me right over the edge. :)

I'm new to this and read we shouldn't use real names. Since I'm not used being incognito, I just signed my real name "Larry" out of habit, don't really care if anyone knows my real name,anyway, I just appreciate the answer. I'll check out the generic,
Thanks, Larry...Uh....I mean Sam.

I tried all of the Big 3 pills with no luck and started on trimix at around 5 months.  I wasn't crazy about the idea of sticking Mr. Happy with a needle at first, but I was very motivated and willing to try about anything to get things working.  As it turns out the injections are simple, painless most of the time, only an occasional little sting during injection and well worth the results I get. 

If you can get results with the pills, great, if not you may want to talk to your Dr. about Trimix or Bimix. 

Good luck,

I was taking Viagra and Cialis before my prostate cancer surgery but would usually alternate the drugs. My blood pressure medication gave me the ED and I couldn't switch to a different BP medication. My primary care doctor wrote a script for the max doses on each but I cut both pills in half before using and then doubled the number that I had for each month. Would use the Cialis on weekends and Viagra during the week. But the Cialis never lasted for 36 hours, was usually good for only 24 hours. I also overlapped taking both and never had any adverse reactions.

Go with the program suggested by your specialist, he knows your condition better than anyone else. If you don't trust that advice, find a Urologist in whom you have more confidence. What works for one of us won't for another - and self-medicating can be dangerous.
