Arestin eent and Fyavolv
Determining the interaction of Arestin eent and Fyavolv and the possibility of their joint administration.
In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.
Consumer:Antibiotics such as minocycline may reduce the effects of ethinyl estradiol in some women. If you are using ethinyl estradiol for birth control, you may be at increased risk for pregnancy or breakthrough bleeding. Talk to your healthcare provider to determine if you should use an alternative or additional form of birth control during treatment with minocycline. In addition, some birth control preparations may include "placebo" non-hormonal pills that contain iron. If you are taking these iron pills during treatment with minocycline, you should separate the dosing times by several hours so that the iron does not interfere with absorption of the antibiotic. Ask your doctor or pharmacist for information on when best to take these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:ADDITIONAL CONTRACEPTION RECOMMENDED: The effectiveness of estrogen-containing oral contraceptives may be impaired by concomitant treatment with antimicrobial agents. However, the risk appears to be small, and supportive data are primarily limited to anecdotal evidence from case reports and findings from uncontrolled or poorly controlled studies. Most antimicrobials, with the exception of the rifamycins and possibly griseofulvin, do not induce hepatic enzymes and have not been shown to significantly increase the clearance of oral contraceptive estrogens. Some investigators believe that antimicrobials interfere with the enterohepatic recirculation of estrogens by decreasing bacterial hydrolytic enzymes in the gastrointestinal tract that are responsible for regenerating parent estrogen molecules following first-pass metabolism. It is possible that a small number of women may be more susceptible to contraceptive failure and, consequently, are more sensitive to the effects of antimicrobials on estrogen disposition in vivo, but risk factors or genetic predispositions have yet to be identified.
MANAGEMENT: Until further data are available, women using oral contraceptives should be advised of the risk of breakthrough bleeding and unintended pregnancy during concomitant antimicrobial therapy. Alternative or additional methods of birth control should be considered during and for at least one week beyond the last dose of short-term antimicrobial therapy, and for at least the initial weeks of long-term antimicrobial therapy when risk may be the greatest.
ADJUST DOSING INTERVAL: The non-hormonal placebo pills included in some oral contraceptive preparations may contain iron, usually ferrous fumarate. Concomitant administration of these iron pills may significantly decrease the gastrointestinal absorption of antibiotics such as quinolones and tetracyclines. The mechanism is chelation of the antibiotic by the iron cation, forming a complex that is poorly absorbed from the gastrointestinal tract.
MANAGEMENT: In general, quinolone antibiotics should be dosed either 2 to 4 hours before or 4 to 6 hours after iron preparations to minimize the potential for interaction. The administration of tetracycline antibiotics and iron preparations should be separated by at least three to four hours, although this may not prevent the interaction with doxycycline. Concomitant use of doxycycline and iron preparations should be avoided if possible.
