Is it true that penicillin kills your natural defense system?

What can you do to prevent it or to limit that problem if it is true?

It kills the bacteria in your bowels. Eat yogurt while on it and you should be fine.

Prolonged use of antibiotics, not only of penicillin, can kill the natural and beneficial bacterial flora in our body. This is the reason why most antibiotics are prescribed for a certain period only, and it is usually specific for the bacteria. This is to make sure that the good bacteria still remains. To make sure that this doesn't happen, do not take antibiotics if not needed, follow the right dosage and the number of days you have to take it.

Yup,however, if you are seriously ill take the medication or you could become more ill. you have to outweigh the pluses and minuses. it's not a good idea every time you get the sniffles to run to antibiotics and a severe illness than yes i would take them.
