Zenegra 50 mg contains sildenafil citrate, the same active ingredient as Kamagra or Viagra. About Addictiveness Sildenafil is not physically addictive. It does not cause chemical dependence like opioids, nicotine, or alcohol. Psychological dependence is possible for some men if they rely on it to feel confident during ***** activity, but this is not the same as true drug addiction. Key Points No tolerance buildup: Your body doesn’t need higher doses over time to get the same effect (unless prescribed differently by a doctor). No withdrawal symptoms: Stopping Zenegra will not cause cravings or physical withdrawal. Safe use: It should only be used as directed by a doctor. Overuse or using without medical guidance may increase side effects, not cause addiction.
