Contra indication of anti biotics?

What are some contra indications of taking anti biotics?

Contra indications vary depending on what type of antibiotics you use.

Here is general contra indications:

SIDE EFFECT:
Antibiotics may have side effects. Some of the more common side effects may include:

* Soft stools or diarrhea
* Mild stomach upset

You should notify your doctor if you have any of the following side effects:
* Vomiting
* Severe watery diarrhea and abdominal cramps
* Allergic reaction (shortness of breath, hives, swelling of your lips, face, or tongue, fainting)
* Vaginal itching or discharge
* White patches on your tongue

ALLERGY

Some people are allergic to certain types of antibiotics, most commonly penicillin. If you have a question about a potential allergy, ask your doctor or pharmacist before taking the medicine.

Allergic reactions commonly have the following symptoms:

* Shortness of breath
* Hives
* Itching
* Swelling of your lips, face, or tongue
* Fainting

I know that most of the time people have reactions to anti biotics because the wrong one was prescribed to them (my brother and myself are very sensitive to antibiotics and have experienced vomiting a lot of times.) also it is always good to use interflora together with your antibiotics so that it doesn't upset your stomach.
(I personally think this is a must)
