What is Doxyvit?

Doxyvit is a tetracycline antibiotic that fights bacteria in the body.

Doxyvit 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.

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

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

Doxyvit 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 Doxyvit and Doxyvit CAP and other antibacterial drugs, Doxyvit and Doxyvit 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.

How should I use Doxyvit?

Use Doxyvit tablets as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Doxyvit dosage

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

Doxyvit® (Doxyvit) 20 mg twice daily as an adjunct following scaling and root planing may be administered for up to 9 months. Doxyvit® (Doxyvit) should be taken twice daily at 12 hour intervals, usually in the morning and evening. It is recommended that if Doxyvit® (Doxyvit) is taken close to meal times, allow at least one hour prior to or two hours after meals. Safety beyond 12 months and efficacy beyond 9 months have not been established.

Administration of adequate amounts of fluid along with the tablets is recommended to wash down the drug and reduce the risk of esophageal irritation and ulceration..

What other drugs will affect Doxyvit?

Medications containing metal ions (antacids, products containing iron, magnesium, calcium) form inactive chelates with Doxyvit, 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 Doxyvit).

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

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

Alti-Doxyvit reduces the reliability of contraception and increases the frequency of breakthrough bleeding while taking estrogen-containing oral contraceptives.
