Product Description

Generic Doxycycline is a 2nd generation tetracyclines antibiotics, active against bacterial strains resistant to classical tetracyclines. It has a high fat-soluble level and a low affinity for calcium ion, which is very stable in human serum. The active substance is Generic Doxycycline. The main principle of action consists in binding to specific units of bacterial proteins, preventing their growth and thus, treating infections.

Due to a reduced number of resistant bacterial strains, even low concentrations of this antibiotic are making pneumococcus, streptococcus and staphylococcus sensible to it. Generic Doxycycline is more active than tetracycline against aerobic gram-negative bacilli and it is effective in treating infections with Chlamydia and Legionella.

Common use.

The antimicrobial spectrum is a broad one and it is similar to that of tetracycline. Thus, Generic Doxycycline may be used to treat:

  1. sexually transmitted diseases
  2. respiratory infections
  3. skin infections (more often for severe acne)
  4. urinary tract infections
  5. eye infections
  6. tick fever

As well, people who intend to travel may use this drug to prevent diarrhea, scrub typhus or malaria, if going to areas with strains of malaria.

Administration and dosage.

You should always see a doctor before taking any medicine.

The regular dose for an adult is 200mg of Generic Doxycycline the first day (taken once or two times by 100mg each) and 100mg/per day the next days. In severe infections the maintenance dose remains 200 mg. The treatment will last for at least 2 more days after symptoms disappear. In streptococcus infections the treatment will last for not less than 10 days in order to avoid articular rheumatism or acute inflammation of kidney (glomerulonephritis).

Drug interaction.
