Penegra 100mg tablets contain the maximum single dosage of sildenafil citrate, the active compound renowned for treating erectile difficulties in men. Each potent tablet delivers 100mg of this phosphodiesterase type 5 (PDE5) inhibitor, which enhances blood flow to facilitate firmer, sustainable intimate encounters. While highly effective for many, this strength may induce more pronounced side effects like headaches, flushing, indigestion, and transient visual disturbances. Rare yet serious adverse reactions including priapism and arrhythmias mandate caution. Strict contraindication exists against concurrent nitrate or specific alpha-blocker use due to potentially life-threatening hypotensive episodes. Comprehensive pre-treatment evaluation remains crucial to assess suitability and implement necessary precautions for this maximum-strength sildenafil formulation. Open dialogue with medical professionals ensures informed risk-benefit analysis.
