What is Doxyman-100?

Doxyman-100 is a tetracycline antibiotic that fights bacteria in the body.

Doxyman-100 is used to treat many different bacterial infections, such as acne, urinary tract infections, intestinal infections, eye infections, gonorrhea, chlamydia, periodontitis (gum disease), and others.

Doxyman-100 is also used to treat blemishes, bumps, and acne-like lesions caused by rosacea. Doxyman-100 will not treat facial redness caused by rosacea.

Some forms of Doxyman-100 are used to prevent malaria, to treat anthrax, or to treat infections caused by mites, ticks, or lice.

Doxyman-100 may also be used for purposes not listed in this medication guide.

Usage

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Doxyman-100 and Doxyman-100 CAP and other antibacterial drugs, Doxyman-100 and Doxyman-100 CAP 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.

The chemical designation of this light-yellow crystalline powder is α-6-deoxy-5-oxytetracycline. Doxyman-100 has a high degree of lipoid solubility and a low affinity for calcium binding. It is highly stable in normal human serum. Doxyman-100 will not degrade into an epianhydro form.

The molecular formula for Doxyman-100 hydrochloride hemiethanolate hemihydrate is (C₂₂H₂₄N₂O₈·HCl)₂·C₂H₆O·H₂O and the molecular weight is 1025.89. Doxyman-100 is a light-yellow crystalline powder. Doxyman-100 hyclate is soluble in water, while Doxyman-100 monohydrate is very slightly soluble in water.

Doxyman-100 dosage

THE DOSAGE OF Doxyman-100® (Doxyman-100 hyclate) DIFFERS FROM THAT OF Doxyman-100 USED TO TREAT INFECTIONS. EXCEEDING THE RECOMMENDED DOSAGE MAY RESULT IN AN INCREASED INCIDENCE OF SIDE EFFECTS INCLUDING THE DEVELOPMENT OF RESISTANT MICROORGANISMS.

Doxyman-100® (Doxyman-100 hyclate) 20 mg twice daily as an adjunct following scaling and root planing may be administered for up to 9 months. Doxyman-100® (Doxyman-100 hyclate) should be taken twice daily at 12 hour intervals, usually in the morning and evening.

What other drugs will affect Doxyman-100?

Medications containing metal ions (antacids, products containing iron, magnesium, calcium) form inactive chelates with Doxyman-100, in connection with what it is necessary to avoid their simultaneous use.

It needed to avoid combination with penicillins, cephalosporins, bactericidal action and is an antagonist of bacteriostatic antibiotics (including Doxyman-100).

Absorption of Doxyman-100 is reduced by cholestyramine and colestipol (observe the interval between the reception of at least 3 h).

Due to suppression of intestinal microflora Doxyman-100 reduces prothrombin index which requires dose adjustment of indirect anticoagulants.
