Before taking Suhagra 25 , inform your healthcare provider about any medical conditions you have, especially heart problems, high or low blood pressure, liver or kidney disease, bleeding disorders, or any allergies. Also, disclose any medications you are currently taking, including prescription drugs, over-the-counter medications, herbal supplements, and recreational drugs, as they may interact with sildenafil citrate. Suhagra should not be used in combination with nitrates or nitric oxide donors, as this can cause a severe drop in blood pressure.
