Yes, Malegra, which typically contains sildenafil as its active ingredient, can have some adverse effects, similar to other medications used for erectile dysfunction. Some users may experience redness or warmth in the face and neck. Some may experience blurred vision or changes in color perception. A prolonged and painful erection lasting more than 4 hours, requires immediate medical attention. It’s important to consult a healthcare provider before using Malegra to discuss potential side effects and interactions with other medications or health conditions.
