Cenforce FM 100 mg is a medication primarily used for the treatment of erectile dysfunction in men. It contains the active ingredient sildenafil citrate. When it comes to combining medications like Cenforce FM 100mg with antibiotics, it's essential to consult with a healthcare professional or a pharmacist. Certain antibiotics, particularly those in the macrolide class like erythromycin or clarithromycin, can interact with sildenafil citrate and increase the risk of side effects such as low blood pressure, fainting, and prolonged erection (priapism). Other antibiotics, like rifampin, may decrease the effectiveness of sildenafil. Therefore, it's crucial to inform your healthcare provider about all medications you are taking, including antibiotics, to ensure there are no potentially harmful interactions. They can provide personalized advice based on your medical history and current medications.
