Is it dangerous to take to much Viagra at one time. Wanted to try and take 1 1/4 or 1 1/2 100mg Viagra this weekend.??? Things are going well according to surgeon but Im only succesfull 50% of the time with entry or intercourse. No problem with self stimulation as far as erection goes but its important to keep the wife happy lol!

yes, like any medication too much is bad. viagra can dangerously lower your blood pressure. You really need to talk to the doctor before doing anything not prescribed.

Viagara comes in several strengths, if your doctor prescribed you at a low dose you may want to talk to them about adjusting it. My doctor prescribed 50 mg. but told me to take 2 (100 mg )if I didn't find it effective.

Successful 50% of the time 15 weeks out? You're no doubt the envy of many guys. :)

Try taking in on an absolutely empty stomach. Even several hours between a meal and Viagra has a significant impact on efficacy for me.

Depending on why you are trying to get the mega erection, she may prefer you not OD on Viagra.

Based on a sample size of one, I can safely say that it's more of a guy thing than a post menopausal gal thing that harder is better.

With respect to the blue pill, hard to say how much it works because of the medicine itself, and how much it works instead because of the psychological feeling that it will work.Try not to overthink it.

Viagra is a phosphodiesterase 5 inhibitor. It blocks the action of an enzyme that causes Mr. Unreliable to deflate. Viagra won't give you an erection but once you have one it will help you hold onto it longer.

While it is designed to be very specific for blocking PDE 5 it also interferes with PDE 6 in higher doses. PDE 6 is used in the retina of the eye to make the rods less sensitive to light in bright-light situations. Big doses of Viagra tend to make the eye more sensitive to bright light and to blue light. The effect is temporary and harmless. The contraction of the pupil will protect the eye from damaging amounts of light, but the world will turn blue and smeary and it will be very hard to see in full sunlight. (Levitra and Cialis also do this but not as often as Viagra) It also appears to slightly dilate the blood vessels in the eye but repeated studies have failed to show any damage from this. (Viagra headaches and runny noses may be related

So I'd talk to your doctor about that extra bit of Viagra. The 100mg pill, taken on an empty stomach, will give you all the effect you are going to get and adding more of the drug will add very little more effect but quite a bit more side-effect.
