Lactulose, which is part of the Ecositrin® preparation, eliminates the risk of side effects associated with the negative effect of the antibiotic on intestinal microbiocenosis.

From the cardiovascular system: ventricular tachycardia, including type of "pirouette", flutter and ventricular fibrillation, increased QT interval on the ECG.

From the urinary system: interstitial nephritis.

Laboratory indicators: leukopenia, hypercreatininemia, hypoglycemia (including while taking hypoglycemic drugs).

Allergic reactions: skin rash, itching, urticaria, skin hyperemia, malignant exudative erythema (Stevens-Johnson syndrome), toxic epidermal necrolysis, anaphylactic reactions.

Other: secondary infections (development of resistance of microorganisms).

Drug Interaction

When co-administered with clarithromycin and drugs initially metabolised by the CYP3A isoenzyme, it is possible to increase their concentrations mutually, which may enhance or prolong both therapeutic and side effects. Contraindication with co-administration with astemizole, cisapride, pimozide, terfenadine, ergotamine and other alprazolam ergot alkaloids is contraindicated, midazolam, triazolam. srdl srdl are prescribed with carbamazepine, cilostazol, cyclosporin, disopirmid, lovastatin, methylprednisolone, omeprazole, indirect anticoagulants (including warfarin), quinidamil, rifabutin, sildamil (metabolized through other cytochrome P450 isoenzymes).

When used together with cisapride, pimozide, terfenadine and astemizole, it is possible to increase the concentration of the latter in the blood, increase the QT interval, arrhythmia, including ventricular tachycardia, including like pirouette, and ventricular fibrillation. Need to adjust the dose of drugs and control the concentration in the blood.

When used together with ergotamine and dihydroergotamine, acute poisoning with ergotamine (vascular spasm, ischemia of the extremities and other tissues, including the CNS) is possible.

Efavirenz, nevirapine, rifampicin, rifabutin and rifapentin (cytochrome P450 inducers) reduce plasma clarithromycin and attenuate the therapeutic effect of the latter, and at the same time increase the level of 14-hydroxyclarithromycin.

Fluconazole 200 mg daily co-administration and clarithromycin 1 g / d may increase CSS and AUC of clarithromycin by 33% and 18%, respectively. No dose adjustment of clarithromycin is required.

Co-administration of ritonavir with 600 mg / day and clarithromycin 1 g / day may reduce clarithromycin metabolism (Cmax increase by 31%, CSS by 182% and AUC by 77%), complete suppression of the formation of 14-hydroxyclarithromycin. In patients with chronic renal insufficiency, dose adjustment is necessary: ​​with Cl creatinine 30-60 ml / min the clarithromycin dose should be reduced by 50%,

When combined with quinidine and disopyramide, ventricular tachycardia of the type "pirouette" may occur. ECG monitoring (QT interval increase), serum concentrations of these drugs are needed.

Clarithromycin increases concentrations of HMG-CoA reductase inhibitors (lovastatin, simvastatin). The development of rhabdomyolysis in patients taking these drugs may be possible.

Clarithromycin and omeprazole may increase Cmax, AUC and T1 / 2 omeprazole by 30, 89 and 34%, respectively. The average pH in the stomach for 24 h was 5.2 - when receiving only omeprazole and 5, 7 - when taking omeprazole together with clarithromycin.

When using clarithromycin and indirect anticoagulants, the latter may be enhanced.

When using clarithromycin with sildenafil, tadalafil or vardenafil (phosphodiesterase-5 inhibitors), an increase in the inhibitory effect on phosphodiesterase may occur. Dose reduction of sildenafil, tadalafil and vardenafil may be required.

When used together with clarithromycin with theophylline and carbamazepine, it is possible to increase the concentration of the latter in the systemic circulation.

Reduction of tolterodine in the presence of clarithromycin (CYP3A inhibitor) may be required when using clarithromycin with tolterodine in patients with low metabolism through CYP2D6.

Co-administration of clarithromycin (1 g / day) with midazolam (orally) may increase the midazolam AUC by 7-fold. Co-administration of clarithromycin with midazolam and other benzodiazepines metabolised by CYP3A (triazolam and alprazolam) should be avoided. Dose adjustments may be required with midazolam (I / O) and clarithromycin. The same precautions should be applied to other benzodiazepines metabolised by CYP3A. For benzodiazepines whose elimination is independent of CYP3A (temazepam, nitrazepam, lorazepam), clinically significant interaction with clarithromycin is unlikely.

When administered with clarithromycin with colchicine, colchicine may be enhanced. Control of the possible development of clinical symptoms of colchicine intoxication is necessary, especially in the elderly and in patients with chronic renal failure (fatal cases have been reported).

When co-administered with clarithromycin and digoxin, serum digoxin concentration should be carefully monitored (possibly increasing its concentration and developing potentially lethal arrhythmias).

Concurrent administration of clarithromycin and zidovudine to adult HIV-infected patients may result in decreased CSS of zidovudine. Dose selection of clarithromycin and zidovudine is required. This type of interaction does not occur in HIV-infected children receiving clarithromycin as a suspension with zidovudine.

Co-administration of clarithromycin (1 g / day) and atazanavir (400 mg / day) may increase the atazanavir AUC by 28%, clarithromycin 2-fold, and decrease the AUC of 14-hydroxyclarithromycin by 70%. In patients with Cl creatinine 30-60 ml / min, the clarithromycin dose should be reduced by 50%. Clarithromycin at doses in excess of 1 g / day should not be administered with protease inhibitors.

Co-administration of clarithromycin and intraconazole may increase the plasma concentrations of drugs. Patients receiving itraconazole and clarithromycin should be closely monitored for possible enhancement or prolongation of the pharmacological effects of these drugs.

With the simultaneous administration of clarithromycin (1 g / day) and saquinavir (in soft gelatin capsules, 1200 mg 3 times daily), it is possible to increase the AUC and CSS of saquinavir by 177 and 187%, respectively, and clarithromycin by 40%. With the joint administration of these two drugs for a limited time in the doses / dosage forms indicated above, No dose adjustment is required.

Co-administration with verapamil may reduce blood pressure, bradyarrhythmia and lactic acidosis.
