People often refer to Viagra as the “little blue pill” or simply the “blue pill.” The reason is obvious — Viagra tablets are small, blue, diamond-shaped pills. Generic Viagra tablets, which contain the active ingredient sildenafil citrate, are often blue, but not always. The tablet's color does not affect how well the medication works. A white sildenafil pill (generic Viagra) works exactly the same as a blue Viagra pill because it also contains sildenafil citrate. No, not every blue pill is Viagra.

Drug form and strengths

Other blue pills can include Xanax® (alprazolam), Adderall® (amphetamine pills for men and dextroamphetamine), Vicodin® (hydrocodone), and Percocet® (oxycodone). Knowing that not every blue pill is Viagra is important because there’s a growing trend of men who don’t have ED taking Viagra recreationally in an effort to improve sexual performance. To access the medication without a prescription, they may turn to illegal drug sellers and online pharmacies, which are infamous for selling counterfeit prescription drugs. Some counterfeit ED medications have been found to contain inconsistent doses of the active ingredient and contaminants like talcum powder, commercial paint, and printer ink. Even worse, these pills may also include other hidden drugs, including opioids. Following a healthy diet, limiting alcohol, exercising, and losing weight are just a few lifestyle tweaks you can make to improve and prevent erectile dysfunction.
