When it comes to different types of medications such as that of antibiotics or drugs that are intended for the treatment of bacterial infections, it is very important that you must learn and understand what the correct antibiotics dosage is for a particular situation.
The elevating instances of microbial and bacterial resistance have become a problem worldwide at this day and age, and we are at higher risk of getting such resistance due to the rare occurences of discovering new antibacterial medications. This renders us to become more and more dependent upon the use of antibiotics, and we do not think much about how high the antibiotics dosage we sometimes use in even the simplest situations – we only aim to get rid of the bacterial infection plaguing us immediately, and with that in mind, we tend to bombard our bodies with high antibiotics dosage amounts in order to eliminate the bacteria once and for all.
These days, there are doctors who strongly believe that the safest and most effective strategy for wise antibiotics dosage use is to only prescribe a specific antibiotic (with the correct antibiotics dosage) only if it is truly needed. Once this is established, the next thing to do is to determine the proper antibiotics dosage. The doctor will usually choose an antibiotic at its lowest yet effective antibiotics dosage spectrum, and something that could present the fewest side effects and it would also be better if the price of the antibiotics is affordable for the patient.
Below are the fundamentals of doctors when it comes to prescribing an antibiotic:
- Make sure to prescribe antibiotics for cases of bacterial infections if: the symptoms are severe and obvious; the infection is not going away; and there is a high chance of complications from occurring.
- Prescribe initially the first-choice antibiotics with the lowest yet effective enough antibiotics dosage.
- Set aside as a last resort the broad-spectrum antibiotics for specific conditions only.
The fundamentals listed above are basically simple guidelines for doctors and other medical personnel on how to effectively prescribe an antibiotic along with its proper antibiotics dosage. Depending on the patient’s individual situation, tolerability and resistance to the drugs, the doctor may change or revise his antibiotic treatment choices.
Sample of an antibiotics dosage guide used in adults:
|Antibiotic name||Antibiotics dosage||Antibiotics dosage form||Antibiotics dosage interval|
|Amoxicillin||500 mg – 1000 mg||250 mg and 500 mg capsule; or 125 mg and 250 mg chewable tablet||Every 8 hours|
|Azithromycin||500 mg first day, then 250 mg for 4 days||250 mg tablet||Every 24 hours|
|Metronidazole||250 mg500 mg||250 mg tablet||Every 6 hoursEvery 8 hours|
A good example of antibiotics dosage based on the bacterial infection or ailment that needs to be treated: Pertussis or whooping cough – The correct antibiotics dosage has to be given in order to minimize the transmission. The right antibiotics dosage needs to be started within the first 3 weeks just after the onset of the cough, since after this time, most patients are no longer considered contagious. If the patient does not know when the cough had started, then it is best to give some antibiotic treatment with the right antibiotics dosage amount. The first choice of antibiotic for pertussis is azithromycin in children, and erythromycin in adults.
