The antibiotic is generally used in treating vaginal infections, bacterial infections of the stomach, skin, joints and respiratory tract. The drug, though an antibiotic, will not cure cold, flu and viral infections, and thus should not be used for same.
Apart from human beings, the antibiotic is also used in treating health problems in dogs and cats. Though safety of this drug can only be guaranteed by the doctor, it is as such not dangerous. But before using the antibiotic, tell your doctor all your health worries and history of any disease you had or have, so that it is easy for him / her to determine the safety of this drug for you specifically.

I repeat it again - consult the doctor before using it, and its safety is then guaranteed.
