Before taking Fildena 150 mg, inform your healthcare provider about any medical conditions you have, especially if you have a history of cardiovascular disease, low blood pressure, liver or kidney problems, or if you are taking medications that may interact with sildenafil citrate. It's also important to avoid alcohol and grapefruit juice while taking Fildena, as they may increase the risk of side effects. https://www.onemedz.com/product/fildena-150-mg/
