The dicloxacillin is an antibiotic drug restricted use. It is a medicine that belongs to the group of penicillins. It is used to treat infections caused by bacteria, and acts as an inhibitor of the development of the bacterial cell wall , destroying it. By slowing down this biological process, microorganisms die and it is impossible for them to reproduce.Dicloxacillin is usually administered against bacteria resistant to other penicillins , and its doses can be administered orally in pills, tablets, or capsules; or intravenously, in solution. The most common way is in capsules.Its commercial presentations contain between 12 and 20 capsules with powder. These come with 250mg and 500mg loads of dicloxacillin sodium. The injectable solution is distributed in ampules with 250mg or 500mg of dicloxacillin sodium.

What is dicloxacillin for?

Dicloxacillin, as an antibiotic drug, is used to:

  • Destroy pathogenic bacteria
  • Treat various infectious diseases
  • Fight bronchitis
  • Treat bacterial tonsillitis
  • Cure pneumonia
  • Treat septic arthritis
  • Fight bacterial cellulite
  • Treat osteomyelitis

Destroy pathogenic bacteria

Dicloxacillin is indicated in the treatment of bacterial infestations such as:

  • Bordetella pertussis
  • Chlamydophila pneumoniae
  • Staphylococcus aureus
  • Hemolytic streptococcus
  • Mycoplasma pneumoniae
  • Other pneumococci

Its function is specific for certain infections, being useless or very little useful in some other bacterial infections.

Treat various infectious diseases

Dicloxacillin, as an antibiotic, attacks infections that cause disease.

Dicloxicillin is indicated for the treatment and relief of diseases caused by bacteria, which are resistant to other penicillins.

These diseases include:

  • Lung abscess
  • Skin conditions
  • Tonsillitis
  • Septic arthritis
  • Bronchopneumonia
  • Bronchitis
  • Bacterial cellulitis
  • Pulmonary empyemas
  • Wound infections
  • Pharyngitis
  • Hydrosadenitis
  • Impetigo (ampollosoforunculosis)
  • Pneumonia
  • Osteomielitis
  • Piodermitis
  • Piomiositis
  • Scaled skin syndrome

Fight bronchitis

Dicloxacillin is used to fight infectious inflammation of the bronchi , called bronchitis. This is caused by various pathogens such as Streptococcus , Bordetella pertussis , Mycoplasma pneumoniae and Chlamydophila pneumoniae .

Treat bacterial tonsillitis

Dicloxacillin fights Streptococcus pyogenes , which is a bacterium that usually inhabits the respiratory tract without being harmful for a time, until it causes infection when the patient’s defenses are vulnerable.

The drug kills Streptococcus pyogenes , making it ideal when this bacterium has begun to develop resistance to common antibiotic medications.

Cure pneumonia

Dicloxacillin is used in cases of persistent and chronic pneumonias, since this drug eliminates the pneumococci that infect the respiratory system, producing this picture.

Treat septic arthritis

This antibiotic is used to combat septic arthritis, which is a condition caused by an infected wound near the joints . It is also produced by pathogenic microorganisms that spread via the blood, affecting the joints.

Dicloxacillin is also used to treat chronic septic arthritis , which is produced by pathogens such as Candida albicans and Mycobacterium tuberculosis .

Fight bacterial cellulite

This medicine is administered to combat Staphylococcus aureus and Streptococcus bacteria , which cause infectious cellulitis in skin areas where there are scrapes or cuts, and where these pathogens enter the skin, infecting it and triggering the picture of bacterial cellulitis.

This infection creates an appearance of stretching in the epidermis, leaving folds and tiny cracks of lighter color in it.

Treat osteomyelitis

Osteomyelitis is a bone infection caused by pathogens such as Staphylococcus aureus bacteria . Dicloxacillin is prescribed to treat these types of internal bone infections, since these pathogens tend to be resistant to other antibiotics.

Contraindications of dicloxacillin

Dicloxacillin attacks microorganisms such as Bordetella pertussis bacteria.

The consumption of an antibiotic is never advisable, without a medical diagnosis and a prescription. All antibiotics, even chemical ones, can trigger adverse reactions like allergies or anaphylactic shock.

It is indicated to prevent the administration of dicloxacillin in people such as:

  • Pregnant women
  • Small children
  • Chronic disease patients
  • Patients who have consumed alcoholic beverages
  • Patients who are consuming tetracyclines
  • Patients sensitive to dicloxacillin
  • Patients with interstitial nephritis
  • Patients with angioneurotic edema
  • Patients with anaphylactic shock

It should not be applied against viruses and viral diseases such as flu, influenza and others, because it only acts against bacteria.

One risk that exists with this antibiotic is that it eliminates or alters the normal microbiota , which are the beneficial microorganisms that work in the body to perform biological functions. Therefore, there may be harmful and opportunistic bacteria that take advantage to invade the organs.

Being a strong antibiotic medicine and presenting these risks, dicloxacillin should be prescribed by qualified medical personnel and should not be self-administered.

Dicloxacillin side effects

The main effect of the indiscriminate use of antibiotics is the generation of resistance of pathogens to drugs , which results in bacteria that are more resistant to antibiotics.

In patients allergic to dicloxacillin, the side effects are:

  • Sickness
  • Threw up
  • Flatulence (gas)
  • Bad breath
  • Gastrointestinal disorders
  • Epigastric pain
  • Anaphylactic reaction
  • Urticaria
  • Itching
  • Itch
  • Jaundice
  • Elevation of TGO-like transaminases

As it is a drug that is often used to treat resistant bacterial infections, it is usually applied only after other antibiotics of less strength have been tried. Its consumption should not be for that long, since in cases of prolonged treatment, some complications such as fungal infestations (of fungi) or, where appropriate, opportunistic bacteria may occur.
