Taking Fildena 120 mg can cause side effects, but most of them are not severe. These side effects can include a tingling or burning sensation in the arms, hands, legs, and feet. They can also lead to a headache or dizziness. These side effects usually go away in less than a week, but if they persist, contact your doctor.
It is also important to take Fildena 200mg at the same time every day. If you take it at different times, then you may not be able to achieve an erection when you are sexually stimulated. This medication is not suitable for people with a history of heart problems, liver or kidney disease. It can also interact with certain medicines, including alpha-blockers, recreational drugs like amyl nitrite and butyl nitrite, and HIV protease inhibitors such as Boceprevir, Telaprevir, and rifampin.
