CONTRAINDICATED: Coadministration with certain macrolide antibiotics may significantly increase the plasma concentrations of ergot derivatives. The mechanism is macrolide inhibition of CYP450 3A4, the isoenzyme responsible for the metabolic clearance of ergotamine and related drugs. Macrolides that may significantly inhibit CYP450 3A4 include clarithromycin, erythromycin and troleandomycin, and clinical ergotism has been reported in patients receiving ergotamine or dihydroergotamine with these agents. Azithromycin and dirithromycin are generally believed to have little, if any, effect on CYP450 3A4.
MANAGEMENT: Given the potential for ergot toxicity characterized by peripheral vasospasm, ischemia, thrombosis, tachycardia and hypertension, concomitant use of ergot derivatives with clarithromycin, erythromycin, or troleandomycin is considered contraindicated. Although clinical data have not been reported, some manufacturers also consider the combination of cabergoline with macrolides contraindicated or to be avoided on theoretical grounds. Azithromycin may be a safer alternative during therapy with ergot derivatives.

Бог его знает, насколько это имеет отражение в клинике, тем более у молодого организма, но, наверное, было бы разумно обсудить другой режим лечения геликобактера, тем более, что терапия первой линии может и не включать макролид.

According to several international guidelines, the first-line therapy for treating H. pylori infection consists of a proton pump inhibitor (PPI) or ranitidine bismuth citrate, with any two antibiotics among amoxicillin, clarithromycin and metronidazole, given for 7–14 days. ... The failure rate for first-line therapy may be higher in actual clinical practice, owing to the indiscriminate use of antibiotics. The recommended second-line therapy is a quadruple regimen composed of tetracycline, metronidazole, a bismuth salt and a PPI. The combination of PPI–amoxicillin–levofloxacin is a good option as second-line therapy.
