There are many products which claim to kill parasites, but they are either ineffective or are harmful in small or large numbers. If you are considering a product for your own use, please be aware that parasites are not always present in any animal and are not always visible to the naked eye. It is important that you get tested for parasites before you buy a product to make sure it is effective. Many of these products are effective for the first couple of weeks, and then disappear from your system. Some products may cause symptoms if used for longer periods. If you don't have a personal health insurance, or if your health insurance does not cover your expenses, the price is typically more than your annual health insurance deductible. Please don't be mislead by a false sense of security by purchasing a product which does not work. Always do a risk-benefit analysis to determine the potential health risks you may be exposed to from a product before buying. If you are unable to afford a personal health insurance plan, you should consider buying a generic drug that does not have any side effects.
