  • Lymphogranuloma venereum caused by Chlamydia trachomatis.
  • Psittacosis (Ornithosis) due to Chlamydia psittaci.
  • Trachoma caused by Chlamydia trachomatis, although the infectious agent is not always eliminated, as judged by immunofluorescence.
  • Inclusion conjunctivitis caused by Chlamydia trachomatis.
  • Nongonococcal urethritis, endocervical, or rectal infections in adults caused by Ureaplasma urealyticum or Chlamydia trachomatis.
  • Relapsing fever due to Borrelia recurrentis.

  • Plague due to Yersinia pestis.
  • Tularemia due to Francisella tularensis.
  • Cholera caused by Vibrio cholerae.
  • Campylobacter fetus infections caused by Campylobacter fetus.
  • Brucellosis due to Brucella species (in conjunction with streptomycin).
  • Bartonellosis due to Bartonella bacilliformis.
  • Granuloma inguinale caused by Calymmatobacterium granulomatis.

Minocycline is indicated for the treatment of infections caused by the following gram-negative microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug:

  • Escherichia coli.
  • Enterobacter aerogenes.
  • Shigella species.
  • Acinetobacter species.
  • Respiratory tract infections caused by Haemophilus influenzae.
  • Respiratory tract and urinary tract infections caused by Klebsiella species.

MINOCINŽ Pellet-Filled Capsules are indicated for the treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug:

  • Upper respiratory tract infections caused by Streptococcus pneumoniae.
  • Skin and skin structure infections caused by Staphylococcus aureus. (Note: Minocycline is not the drug of choice in the treatment of any type of staphylococcal infection.)

When penicillin is contraindicated, minocycline is an alternative drug in the treatment of the following infections:

  • Uncomplicated urethritis in men due to Neisseria gonorrhoeae and for the treatment of other gonococcal infections.
  • Infections in women caused by Neisseria gonorrhoeae.
  • Syphilis caused by Treponema pallidum subspecies pallidum.
  • Yaws caused by Treponema pallidum subspecies pertenue.
  • Listeriosis due to Listeria monocytogenes.
  • Anthrax due to Bacillus anthracis.
  • Vincent's infection caused by Fusobacterium fusiforme.
  • Actinomycosis caused by Actinomyces israelii.
  • Infections caused by Clostridium species.

In acute intestinal amebiasis, minocycline may be a useful adjunct to amebicides.

In severe acne, minocycline may be useful adjunctive therapy.

Oral minocycline is indicated in the treatment of asymptomatic carriers of Neisseria meningitidis to eliminate meningococci from the nasopharynx. In order to preserve the usefulness of minocycline in the treatment of asymptomatic meningococcal carriers, diagnostic laboratory procedures, including serotyping and susceptibility testing, should be performed to establish the carrier state and the correct treatment. It is recommended that the prophylactic use of minocycline be reserved for situations in which the risk of meningococcal meningitis is high.

Oral minocycline is not indicated for the treatment of meningococcal infection.

Although no controlled clinical efficacy studies have been conducted, limited clinical data show that oral minocycline hydrochloride has been used successfully in the treatment of infections caused by Mycobacterium marinum.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Minocin (minocycline hydrochloride) Pellet-Filled Capsules and other antibacterial drugs, Minocin (minocycline hydrochloride) Pellet-Filled Capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Adjuvant therapy with minocycline for schizophrenia (The MINOS Trial): study protocol for a double-blind randomized placebo-controlled trial. [2013]
BACKGROUND: Schizophrenia is understood to be a heterogeneous brain condition with overlapping symptom dimensions. The negative symptom dimension, with its protean cognitive manifestations, responds poorly to treatment, which can be a particular challenge in countries where clozapine therapy is not available.

High MMP-9 activity levels in fragile X syndrome are lowered by minocycline. [2013]
Fragile X syndrome (FXS) is a neurodevelopmental disorder characterized by lack of the FMR1 protein, FMRP, a translational repressor... The results of this study suggest that, in humans, activity levels of MMP-9 are lowered by minocycline and that, in some cases, changes in MMP-9 activity are positively associated with improvement based on clinical measures.

Clinical Trials Related to Minocin (Minocycline)

A Phase II Study of Minocycline and Armodafinil for Reducing the Symptom Burden Produced by Chemoradiation Treatment for Esophageal Cancer [Not yet recruiting]
The goal of this clinical research study is to compare armodafinil and minocycline when given alone or in combination to learn which is better for controlling side effects of chemoradiation treatment for esophageal cancer (such as fatigue, pain, disturbed sleep, lack of appetite, and drowsiness).

Armodafinil is designed to prevent excessive sleepiness.

Minocycline is an antibiotic, which may help to reduce multiple symptoms.

In this study, you may receive a placebo. A placebo is not a drug. It looks like the study drug but is not designed to treat any disease or illness. It is designed to be compared with a study drug to learn if the study drug has any real effect.

A Study for Reducing Symptom Burden Produced by Chemoradiation Treatment for Non Small Cell Lung Cancer by Minocycline and Armodafinil [Recruiting]
The goal of this clinical research study is to compare armodafinil and minocycline when given alone or in combination to learn which is better for controlling symptoms, such as the side effects of chemoradiation, when given to treat lung cancer.

Adjunctive Minocycline in Clozapine Treated Schizophrenia Patients [Recruiting]
Schizophrenia is a devastating and costly illness. One-third to one-half of people with schizophrenia do not respond to the most current drugs leaving clozapine as the best alternative for treatment. However, over 60% of people treated with clozapine continue to have persistent symptoms and cognitive impairments. Little data is available to support evidence-based recommendations to guide clinicians in treating these patients. Preliminary data has suggested that adjunct treatment with minocycline may offer robust symptom improvement in patients with schizophrenia, including those taking clozapine. Minocycline has had interesting effects; including suggesting it may have a significant role in treatment of neurologic and psychiatric disorders. Minocycline is currently available generically; its side effects are well-described and minimal. The proposed double-blind treatment study seeks to demonstrate that adjunctive minocycline offers patients superior efficacy for persistent positive symptoms, cognitive impairments, and/or other components of schizophrenia pathology. This knowledge could lead to the more effective treatment of patients with schizophrenia. The research itself may lead to a better understanding of the pathophysiology of positive symptoms and cognitive impairments, which could contribute to improved treatments in the future.

Minocycline in Clinically Isolated Syndromes (CIS) and Early Single Relapse Multiple Sclerosis (MS) [Recruiting]
The aim of the trial is to demonstrate that 100 mg of oral minocycline twice daily reduces the conversion of CIS to McDonald Criteria MS (McDMS) by an absolute 25% as compared to placebo, over a 6 month follow-up period (primary outcome).

A key secondary outcome is to confirm that this early treatment benefit is maintained at two years.

Minocycline for Bipolar Depression [Recruiting]
The purpose of this study is to evaluate minocycline as a potential treatment for bipolar depression when added to a mood-stabilizing medication. Minocycline is an antibiotic that is approved for the treatment of infections and acne. Participation in this research study is expected to last 8 weeks, and includes five outpatient visits.

Minocin review by 26 year old female patient

  Rating
Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Moderate Side Effects
  
Treatment Info
Condition / reason:   Cystic Acne
Dosage & duration:   50 MG taken twice a day for the period of About 4 years
Other conditions:   None
Other drugs taken:   just vitamin supplements
  
Reported Results
Benefits:   My cystic acne was reduced. My face did clear up consistently with the help of the pills and creams such as retin-a.
Side effects:   I needed to take the pills with lots of water, so I was always taking trips to the bathroom. I was on this pill for a long time, and I dont know if the constant ringing of my ears was a side effect, I did visit an ear doctor for this problem I thought was tinnitus but the doctor assured me the minocin had nothing to do with it. The ringing of the ears continued for about a year after I stopped taking minocycline. Occasionally I still get a ringing of the years, it can be sudden but lasts for a second or so...I was never diagnosed with tinnutus, but the ringing did lessen until it left after i stopped the pills.
Comments:   I was to take the pills twice a day with water. I took one in the morning after I ate, and one at night with plenty of water....after a year my body became resistant to the pill and stopped working, and i started taking higher doses without my doctors consent..which was wrong of me and dangerous and maybe that is why the ringing of my ears began...but I was obssessed with clearing up my acne. I was young, I believe i was 17 or eighteen when i started minocin and was on and off it for about 4 years.
