Sam's Club pharmacies in some states are selling 20 mg sildenafil tablets at $10 per bottle of 30.
If you (or your partner) don't use Viagra or one of its competitors, that will mean nothing to you. If you do use Viagra, you know the price has risen from about $8 per dose when it was introduced to $45 per dose. That's not per pack, that's per pill. I was checking prices recently, and Rite Aid quoted me $318.99 for 6 doses of Viagra 100 mg, then said they could enroll me in their Rx Savings Program and drop the price to $271.14.
So how did the Sam's Club savings happen? It's a quirk of the drug's development history and US patent laws. Sildenafil was developed as a blood-pressure reduction med, and some of the test subjects begged for additional doses when their testing was done. The investigators asked why, and suddenly a new category of drug was born. Viagra as formulated for treatment of erectile dysfunction is dispensed in tablets of 25 mg, 50 mg, and 100 mg, because it is effective in low doses for some people, and others need higher dosages. Viagra is still protected by patent and there is no official generic version in the matching dosages.
The patent for sildenafil as a blood pressure treatment expired in late 2012. I didn't know that until now. The blood pressure version was called Revatio, and it is available as a generic in tablets of 20 mg. Same stuff, different strength than the ones marketed for ED as Viagra.
Sam's Club offers their Extra Value Drug List (EVDL) to "Plus" members (that's the $100/per year premium membership.) Sildenafil, 20 mg, is on the list for $10 per 30 tablets. If you're used to taking the 100 mg Viagra, you'd need to take five of the generic sildenafil to match the dose. If you're getting results at 25 mg Viagra, maybe 20 mg sildenafil will work for you, and if not you'd need to go up to 2 tabs for 40 mg total. If you're taking 50 mg Viagra, you'd try 2 tabs to total 40 mg, or take 3 to total 60 mg.
You still need a prescription for the stuff, and your doctor might not know about the generic sildenafil. You can show them the Sam's Club list here: http://resources.samsclub.com/MediaICN/2013/HealthyLiving/English_V2.pdf
The Sam's Club EVDL is NOT AVAILABLE in the following states: CA, GA, HI, MA, MD, ME, MN, OK, OR, PA, RI, SC, VT, WI and Puerto Rico. If you're in one of those states, the drive to an out of state Sam's Club might be worth it. And you can check the pharmacies locally to see what they're charging for generic sildenafil.
Remember you need to have the Sam's Club "PLUS" membership at $100. More details on the EVDL program are here: http://resources.samsclub.com/health-and-wellness/pharmacy-and-health/Plus-Member-Pharmacy-Discount.aspx
