bay, i think i may have good news for you, i spoke with a representative with abconlinepharmacy in canada, the site i originally gave you, and they tell me its quite possible to order using a philippine prescription, any prescription is fine so long as it is written in english thats what the person said. you could just fax it to them, and also they deliver to the pihilippines for $USD 4.95 and that will take about 2-3 weeks though im sure that some speedier shipping options are available. and the best thing about this is, you can order from there all you'll need is a credit card.
now everything seems fine but the problem is, i have never ordered drugs online so i cannot verify the reputation and merit of these sites though at face value it looks ok. my mom did tell me about how she saw a documentary in tv about some fake drugs in canada. as a rule medication there is much cheaper in the u.s so the trend has been that people here buy from there, unfortunately some people are exploiting this fact and are introducing fake drugs to rip people, mostly senior citizens off.
i advise you to think things over, visit their site try to get a feel for it, ask your questions (there is a livechat function available so you can chat directly with one of their representatives), weigh the risks and advantages involved and do your research so you may make an informed decision. moneywise however you will be able to save a lot and i mean a lot, the prices are half what they are there.
i think i have done just about all that i can do for you, but i am also having my mom ask her pharmacist friend if we could buy the drug here with a philippine prescription and how much that may cost (it will probably be a bit more expensive than the canada prices but should still be cheaper than if you got it there). so i will update you on that when i get the information.
and if you're wondering why im being so helpful, i lost my only brother to cancer, he was 3 years old. that was one of the most painful experiences in my life.
