Cenforce FM 100 mg vs Viagra 100 mg, they are not necessarily “better” than each other for erections. Viagra 100 mg contains sildenafil 100 mg. The usual starting dose is 50 mg, and 100 mg is the maximum recommended dose, taken no more than once daily. D DailyMed Cenforce FM 100 mg is marketed under different formulations depending on the manufacturer. Some listings describe it as sildenafil 100 mg alone, while others list sildenafil 100 mg + dapoxetine 60 mg. C centurionlaboratories.com +1 If your Cenforce FM 100 mg  contains only sildenafil 100 mg, its intended erectile effect should be broadly similar to Viagra 100 mg; the major difference is the manufacturer/product quality and regulatory oversight. If it contains dapoxetine as well, it is a different combination intended to address premature ejaculation in addition to ED. That does not make it a stronger ED treatment and can add side effects/interactions. Don't take Cenforce FM and Viagra together—you could exceed the appropriate sildenafil dose. If you can send me a photo or the exact ingredient list on your Cenforce FM 100 mg package, I can tell you exactly what's in yours and compare it with Viagra.
