Medics divide antibiotics in seven different classes. The class derived from erythromycin, including zithromax, is called the macrolides and they are used to treat a fairly wide range of infections caused by a specific group of bacteria. Their Mode of Action (MOA) is mainly as a bacteriostatic. That means they interfere with the way in which the bacteria manufacture the proteins they need to survive. The result is they stop growing and cannot reproduce.
But, if the dosage is high, the effect becomes bactericidal, i.e. the antibiotic actually kills the pesky bacteria dead. No more hanging around for them to fade away. Warning! This news should not tempt you to take a really high dose of zithromax every time you fall sick. The first issue is for your healthcare provider to confirm your sickness is being caused by a bacterium that will be killed by zithromax. Here’s the bad news. There are several thousand different types of bacteria and only a few of them are killed by zithromax. So, if you take this really powerful drug, it might have absolutely no effect because the cause of your problem is a different bacterium or, worse, you caught a virus. But taking this antibiotic does have an effect.
So, if you are vomiting, your stomach is upset and diarrhea is pouring out of you, this is an emergency and you should go down to your local hospital fast. Used in the right cases and at the right dosage, zithromax is a highly effective medication for the right bacteria. If you abuse it, you could find it seriously affects your health both in the short term and in the long term by reducing its effectiveness should you get an another infection.
