Antibiotics for Sinus Infections

1 Comment

Are there really effective antibiotics for sinus infections? Antibiotics are used for patients who are suffering from certain infections like that of the sinus. The medicine kills the bacteria inside the body which is responsible for the infection. Doctors don’t prescribe antibiotics for viral influenza and common cold because it is ineffective for fighting viruses.

A healthy body can easily fight bacterial infections but this is not the case all the time. Some individuals are not that healthy and this means that their immune system is not working at its best, in short, the immune system is impaired. The white blood cells and the antibodies in some unhealthy individuals are not enough to fight the illness. The most commonly used antibiotics these days are penicillin, ,macrolides, cephalosporins, and flouroquinolones.

Antibiotics can be narrow-spectrum and broad-spectrum. In most cases, doctor prescribes the former kind of antibiotic because it is much cheaper but very effective in treating the bacterial infection. On the other hand, the latter often promotes antibiotic resistance and so it is given when badly needed.

Penicillin and macrolides are both narrow-spectrum antibiotics while the cephalosporins and flouroquinolones are noth broad-spectrum antibiotics.


Bacteria can easily reproduce, thereby multiplying at a fast rate especially when they have entered the host’s body. Penicillin can interfere with the building functions of the bacteria thereby stopping the infections. Amoxicillin is a very good example for treating sinus infections.


This antibiotic blocks or slows down the bacteria’s protein formation. This medicine does not eliminate the bacteria since its primary function is to curb the multiplication of the bacteria. By using the medicine, the immune system will be the one to eliminate the said bacteria. When this antibiotic is administered in large doses, it can also kill certain kinds of bacteria. Clarithromycin and erythromycin are very good examples of this kind of antibiotic. ENT specialists often prescribe clarithromycin for sinus infections.


This is already a broad-spectrum antibiotic and it works by inhibiting synthesis in the bacteria’s cell walls. Individuals who have a penicillin allergy are often given ceftibuten dehydrate which is a 3rd generation cephalosporins. Most ENT experts prescribe this antibiotic for those with penicillin allergic reactions.


Like the cephalosporins, this is another broad-spectrum antiobiotic and it is among the newest class. This antibiotic interferes with the bacterial DNA replication process. For sinus infections, Moxifloxacin is often given to patients.

Doctors can’t just prescribe any antibiotic for the patient suffering from sinus infections. There are certain factors to consider like the cost of the medicine, the allergies of the individual, the possible side effects or serious reactions to the medicine, the illness’ severity and nature, and the rate at which the medicine is eliminated by the body.

Mild infections can be given narrow-spectrum antibiotics such as amoxicillin. Broad-spectrum antibiotics are given to patients with chronic sinus infections. Oftentimes, medical practitioners can’t prescribe the same line of antibiotics because the effects vary from one individual to another. Having a personal doctor is an advantage because he or she is familiar with your medical history.

You can’t use a certain antibiotic without the prescription of your doctor because it can only worsen your condition. Consult your doctor right away if you’re having a sinus infection. That way, your current condition can be assessed thoroughly and a new line of medicines can be prescribed.
