Fildena 120 mg (sildenafil) does not cure erectile dysfunction (ED) permanently. It is a temporary treatment that helps many men achieve and maintain an erection when they are sexually stimulated. It does not remove the underlying cause of ED. Whether ED improves long term depends on the reason behind it. Causes such as: diabetes, high blood pressure or heart disease, obesity, low testosterone, stress, anxiety, or relationship factors, smoking or excessive alcohol use, certain medications, may need separate treatment or Fildena 120 mg changes. Fildena 120 mg is a high dose of sildenafil and should only be used if prescribed or advised by a healthcare professional. Higher doses can increase the chance of side effects such as headache, flushing, dizziness, low blood pressure, vision changes, and heart-related risks in some people. Do not use sildenafil with nitrate medicines (used for chest pain) because the combination can cause a dangerous drop in blood pressure. If you tell me your age, how long you have had ED, any diabetes/BP/heart/liver problems, and whether you use any medicines, I can help explain what may be causing it and what options are usually considered.
