Although most men prefer oral ED medication, including not only Viagra but also Cialis, Levitra, Staxyn, and Stendra, these drugs are incompatible with nitrate-based drugs, making the vacuum pump an alternative ED treatment for men who are taking those drugs for angina.
Also known as a vacuum constrictive device, the vacuum pump also offers an alternative for men who find the side effects of Viagra uncomfortable or troublesome. While these side effects are usually mild and disappear after continuing use of the drug, each individual reacts differently, and some men may prefer avoiding the medication altogether.
That said, the vacuum pump has its own drawbacks, perhaps the most notable of which is the time — 10 to 20 minutes — it takes to achieve an erection strong enough for intercourse. Coupled with the cumbersome mechanical nature of the device and the potential for bruising and penile pain, these disadvantages may make use of the pumps undesirable for many.
