Fildena 150mg is a potent medication for treating erectile dysfunction, but it comes with specific warnings and precautions. It should not be used by individuals with heart conditions, recent strokes, or severe liver and kidney issues. Avoid taking it if you’re on nitrates or other medications for chest pain, as this can lead to a dangerous drop in blood pressure. Alcohol and grapefruit should be avoided as they can interact with the drug and reduce its effectiveness. Consult a healthcare provider before use, especially if you have a history of medical conditions or are taking other medications to avoid complications.
