For healthy individuals with no underlying health conditions, Fildena 150 can generally be considered safe when taken as directed by a healthcare provider. However, it is crucial to avoid exceeding the prescribed dose because taking too much Sildenafil can cause serious side effects, such as severe headaches, dizziness, blurred vision, or an erection lasting more than four hours (priapism), which requires immediate medical attention.

Fildena 150 should not be used by individuals who are taking nitrates (often prescribed for chest pain) or have a history of heart problems, as the combination can cause a dangerous drop in blood pressure. It is also not recommended for those with certain conditions like liver or kidney disorders without medical consultation.

In conclusion, while Fildena 150 and sildigra 250mg can be safe for treating ED, it must be used under medical supervision to minimize the risk of adverse effects.
