Zometa: Novartis or Generic?

As usual there are different opinions about almost everything when it comes to Pca.  Uro A says that he would take the Novartis over the generic.  The generic here in the Phils is from India.  Uro B says the generic is equal, and with the cost savings, it is worth it.  Also, there appears several opinions as to when to administer.  I have heard every three weeks, every month, and even that there is one dosage that can be administered every 10 - 12 weeks that is equally effective.  I know you guys know more than the people I talk to, and, once again, I turn to you for help with great gratitude.  love, swami Rakendra
