No, tetracycline does not receive rid of tapeworm. Whether you are concerned, you should see your physician to have stool samples done to detect parasites. Only then can you know whether you have it, and what medication is needed to get rid of it. No steady antibiotics will help, you need medication tailored to getting rid of parasites.
No, the tetracyllin won't cure them. What you need is something that gets them out. Whether I am not sure if tapeworms fall under the category of parasites, but I think so and for that you can take a curative clay. Parasites cannot reproduce in clay and the body will eliminate them via the normal route....good luck
Unless you've lost a lot of weight and are dizzy and feeling like crap. You need to go to the Dr.
