There are a few disadvantages to buying Fildena online, some of which are discussed in the last section of this article. First of all, buyers beware: some vendors sell fildena pills that might not be entirely truthful about the contents and effectiveness of their products, and they might be selling a concoction of herbs that passes for medicine instead of actual medication. Secondly, before making a purchase, make sure to carefully go over the components list and avoid dealers that withhold any information. Remember also that there might be drug interactions with fildena tablets, including those from GNC (the "Great Northern Company"), since multiple reports of fildena overdose have been made there.
