Effective Antibiotics Against STDs

Antibiotics are a group of drugs that took their origin from Alexander Fleming's discovery in 1928. They are antimicrobial substances used in the treatment and prevention of bacterial infections. They work by killing the pathogenic organisms, or by inhibiting their growth and multiplication.

Since antibiotics are designed to fight against bacterial and certain parasitic infections, they do little or nothing to fight off infections caused by viruses, and allergies.

Antibiotics are classified based on:

  • Their interaction with other drugs when administered to the body together, in working out a needed therapeutic effect
  • The simplicity or complexity of their chemical composition
  • Their range of activities
  • The kind of bacteria they target

When can one use antibiotics?

Ideally, antibiotics should be used after a laboratory or science-based test has been carried out on a person. A culture of the bodily secretion is done, and the result should be out in a day or two.

Be that as it may, STD home test kits have proven to be highly effective in diagnosing these terrible diseases. There are now available strips designed to detect STDs in the blood in jest a few minutes and this can be done at home in a very discreet manner. Once proven by the strip that the blood sample is infected with any type of STD, it is important to consult a health professional (a doctor, in this case), for further treatment.

When one has been diagnosed with the bacterial infection, one is entitled to an antibiotic treatment, depending on the severity of the disease. STDs that require antibiotics include Gonorrhea, Chlamydia, Syphilis, Bacterial Vaginosis and Trichomoniasis.

It is very needful to follow guidelines for the antibiotics treatment of diseases to prevent the resistance of bacteria to the drugs used against them. Resistance to drugs makes the treatment a futile one.


Gonorrhea is a sexually transmitted disease. Given that the use of condoms plays a little role in curtailing the spread of this disease, immediate treatment is best advised. The target organism in the treatment of Gonorrhea is the bacterium, Neisseria gonorrhea.

In treating Gonorrhea, double antibiotic treatment is prescribed. The antibiotics are given intramuscularly in the physician’s office to ensure that the patient is fully compliant with the drug regimen. In many cases, Chlamydia is diagnosed alongside Gonorrhea because both have similar symptoms. Antibiotics used in the treatment of Gonorrhea are:

Ceftriaxone. Ceftriaxone is a part of the double antibiotic therapy with Azithromycin, for treating Gonorrhea. It is a strong antibiotic and prevents the growth of the cell wall of N. gonorrhea. It is given intramuscularly.

Azithromycin. It is the second part of the dual antibiotic regimen against Gonorrhea, with Ceftriaxone. It functions in blocking the replication and protein synthesis of the bacterium. It is also given intramuscularly.

Others are:

Cefixime. It is given orally as a single dose coupled with a single dose of Azithromycin.

Doxycycline is given orally twice daily, with an intramuscular injection of ceftriaxone for complications like epididymitis and pelvic inflammatory disease.

Erythromycin is the only recommended antibiotic ointment for use in newborn babies as a form of prevention against gonorrheal infection in the eyes, most likely to be gotten from their infected mothers.


Chlamydia can be treated with antibiotics. The target organism is Chlamydia trachomatis. Pregnant women and nursing mothers infected with Chlamydia are given Amoxicillin or Erythromycin.

Antibiotics usually prescribed for the treatment of Chlamydia are:

  • Azithromycin, given orally as a single dose
  • Doxycycline, given orally twice daily for up to 14 days

When there are complications, a longer course of treatment is prescribed which may demand being hospitalized or operated on.


For every kind of Syphilis including neurosyphilis and syphilis during pregnancy, Penicillin is the antibiotic of choice. The target organism is Treponema pallidum. Other antibiotics that can be given to patients with an allergy to penicillin are:

  • Doxycycline
  • Erythromycin
  • Ceftriaxone
  • Azithromycin

Bacterial Vaginosis

The antibiotics that can be given to treat Bacterial Vaginosis are used as creams, gels, oral pills or suppositories inserted in the vagina. These antibiotics are:

  • Metronidazole
  • Clindamycin
  • Secnidazole


The target organism is Trichomonas vaginalis. To treat Trichomoniasis, Metronidazole or Tinidazole is prescribed for oral consumption.


Antibiotics for STDs are only effective when taken correctly as prescribed. Inconsistency in drug intake can make the bacteria resistant to the treatment. Until the treatment is completed, do not be involved in any sexual activity. Your partner/s should be treated at the time you are being treated. As always, early detection makes treatment more efficacious. Not having symptoms does not mean that an STD is not present.
