I wanted to share something I found out. When you take Viagra, they ask if you are using any antiacids. It turns out that antiacids like Tagamet fit into the same receptors in your cells as Viagra, making it take much longer for the Viagra to metabolize and leave your body.
If you take a larger dose, this can result in you having excessive levels of Viagra in your system. However, I have found through experimentation that you can take a smaller dose of Viagra (saving a lot of money), along with a Tagamet, and you get the same effect as from a larger dose, plus it lasts twice as long. I generally take a 25mg dose with the Tagamet, and I get what I would normally expect with a 50mg dose, usually with some residual effect still the next morning, so I figure it lasts 10-12 hours.
Supposedly the same is true with Levitra and Cialis, since they work by the same principle. I have not tried these first hand, but I have tried Viagra with and without Tagamet, and the effect is clear. Also, since Cialis lasts longer, I don't know how this interaction works.
I found no negative side effects, except that I did find you have to be more serious about the warning not to drink to excess with Viagra. I found getting moderately drunk after using Tagamet and Viagra together gave me a worse hangover than with Viagra alone, which in turn is noticeably worse than plain drinking with no Viagra.
I found the link below after a quick Google just now, but there are a number of links. I looked at numerous links before deciding to try this, and came to the conclusion it was a safe and effective approach. Of course, I am not a Doctor, and if you try this it's your own responsibility.
Note: I was reading more in the link below, and some recommend a larger dose of Tagamet to get the full effect. I only ever took one Tagamet, and noticed clear results. Others report not noticing any difference. It clearly works for some people, and the metabolic reason for it is clearly documented, hence the drug interaction warnings.
