Even if your doctor prescribed Levaquin or a similar medication, do not just take his word for it and go out and buy it. Often, doctors just give out the things that they are most familiar with. Pharmaceutical companies will also pay a lot of money to have a doctor stock a certain medication; however, is the fact that the company pitched it successfully really why you want to take any type of medicine?
Instead of just going with whatever was first prescribed, you should look around online and read various reviews. Start with the drug that was recommended. What are other people saying about it? Do they generally think that it works, or are they unhappy with the results? Have they noticed any side effects that were not mentioned anywhere else? Do they feel like the price is fair, or would they recommend using something else that does the same thing and costs a bit less? Look for all of this information with the reviews, rather than just reading the star ratings and deciding based on that. You need the details.
You might as well let someone else tell you about their experience before you have one of your own. If they used a medication that failed, why should you also use it, only to find out the exact same thing that they could have told you before? Looking for reviews and then finding and buying the best medications online will provide you with a far more positive experience.
