Online Fildena purchases may have a number of disadvantages, some of which will be discussed in the latter portion of this article. First of all, consumers should be forewarned that some sellers of fildena pills might not be totally truthful about the contents and efficacy of their products, instead using a combination of herbs that appear to be medicines. Second, before making a purchase, be sure to carefully check the components list and avoid any dealers who withhold any information. Additionally, keep in mind that there may be interactions between different medications and fildena tablets, such as those offered by GNC (the "Great Northern Company"), given the volume of documented cases of fildena overdose there.
