If you have heart disease, taking Fildena 200mg requires caution and consultation with a healthcare provider. Sildenafil citrate, the active ingredient in Fildena 200mg, can affect blood pressure and interact with medications used for heart conditions, such as nitrates, potentially leading to severe side effects. It's crucial to inform your doctor about your heart condition and any medications you're taking. They can assess your overall health and determine if Fildena 200mg is a safe option for you, or if a lower dose or alternative treatment might be more appropriate. Never self-medicate or adjust your dosage without medical guidance.
