Antibiotics are medicines that are capable of destroying various kinds of microbes (bactericidal antibiotics) or stopping their multiplication (bacteriostatic antibiotics) in the human body.
After antibiotics discovery, doctors were able to treat many previously considered fatal infections. The minimal dose of simple penicillin during the day relieved the temperature and returned the patient to life. However, after a while drugs dose increased many times, and their effect was significantly reduced.
My Canadian Pharmacy points out that microbes are able to develop resistance to treatment (antibiotic resistance) with frequent contact with the drug. Since then, chemists and pharmacists have been constantly synthesizing new forms of antibiotics, seeking to be half a step ahead of the causative agents of infectious diseases. In the arsenal of doctors there are:
- antibiotics with a selective effect on certain strains of microbes;
- drugs that can accumulate in certain organs and environments of the body and there develop the greatest effect;
- means of short and prolonged action;
- medicines of local and general action.
As in earlier times, antibiotics remain an accurate weapon against infections in skillful hands. However, when used inappropriately, they can cause harm to health, as they have a number of side effects.
When to Take Antibiotics — My Canadian Pharmacy Online Answer
In most cases, the doctor must decide whether to apply antibiotics or not. An exception is the situation when a person is away from civilization and medical assistance is not available. However, in this case it is a therapy of despair, and one must be prepared for mistakes and complications.
Antibiotics are prescribed:
- in case of bacterial diseases development requiring etiotropic therapy. That is, in those cases when the body itself is not able to cope with a bacterial infection. For example, with typical pneumonia, angina, cystitis, pyelonephritis, mastitis, purulent skin diseases.
- For the prevention of bacterial infections in rare cases: after surgical interventions, injuries, complicated labor, with viral diseases in weakened patients, with chemotherapy in oncological patients, etc.
- The effectiveness of antibiotic treatment depends first of all on choice correctness of the drug and its dose.
Reasons for therapy selection:
- the assumption of the most likely causative agent of the disease. Treatment should be appointed from the first days, so the doctor must approach the selection of therapy based on statistical knowledge about the most likely disease’s cause. Usually, only after a week or more it is possible to accurately determine the nature of the pathogen and its sensitivity to antimicrobial agents.
- localization of the pathological focus of the disease (upper respiratory tract, urinary system, gastrointestinal tract, skin and subcutaneous fatty tissue, brain, etc.).
- information on previously used antibiotics and individual tolerability.
- in addition, for calculating the dose, disease’s severity, patient’s weight and age must be taken into account.
The second factor in the effectiveness of therapy is the exact adherence to the rules and the regimen for taking antibiotics by the patient.
When you do not Need to Take Antibiotics
It is not recommended to take antibiotics without a doctor’s appointment in case of:
- virus diseases (ARVI, ARI and influenza): they do not have an effect on viral agents;
- with intestinal disorders: in most cases it is not necessary;
- from temperature: antibiotics do not possess anti-inflammatory and antipyretic effect;
- when you smoke: read more about how smoking influence antibiotics effects — https://mycanadianpharmacyteam.com/canadian-pharmacy-antibiotics-and-smoking.html;
