I am proscribed 25mg of viagra which I buy as 50mg pills to save money and cut in half. Cutting a viagra in half is not easy because they are hard coated and not scored (and oddly shaped). I find that 25mg is a little too much since it has side effects (a low blood pressure feeling, even though I don't think my blood pressure is really low). I have tried cutting the 50mg into fourth (very difficult), but this seems like a little too little. Unfortunately on the few times that I have forgone the viagra I have experienced moderate impotence for the first time in my life. I am able to achieve a half-erection but it is hard to maintain long enough to have an orgasm. When I occasionally masturbate at home, without using viagra, I achieve a rapid erection and orgasm as I've always done since I was 14 years old. I ask because the Lipitor fullpage ads in national magazines say DO NOT BREAK TABLETS and they Lipitor website from Pfizer also says on the meds page DO NOT BREAK TABLETS but my doctor told me to break the 10 mg tabs in half and take just half each day.

Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart.
