Hmm... Well that is a question you should never really be asking the internet, or trying to make guesswork. Usually Streptococcus infections are tested for a variety of features and then dosages are prescribed based on progression and strain of the bacteria. One thing is for certain though, you follow a doctors dosage and specific medication requirement. If you are asking this question because you think you might have a Strep infection, and you do happen to have left over antibiotics... do not take them, If the medication hasn't been tainted in the first place, it's a good way to get certain antibiotic resistant infections.
Toss them in the trash, see your doctor for a prescription and dosage requirements, and follow through with that current prescription.
The answer is:
Age
This is because if your young your organs are not as developed. When your older your body handles more because it is developed fully.
The answer is ...They should check their facts and exchange questions with each other. .
Hope this helps
