• Antacids (medications used for digestive problems). It is recommended to avoid simultaneous administration of both medications at the same time of day.
• Ergotamine derivatives (such as ergotamine, used to treat migraines), as simultaneous administration with azithromycin may cause ergotism (a potentially severe adverse effect with numbness or tingling in the extremities, muscle cramps, headaches, convulsions, or abdominal or chest pain).
• Digoxin (a medication used to treat heart arrhythmias) as azithromycin may elevate digoxin levels in the blood, and levels should be monitored.

• Ciclosporin (a medication used in transplant patients) as azithromycin may elevate ciclosporin levels in the blood, and levels should be monitored.
• Anticoagulant dicumarins (medications used to prevent blood clotting) as azithromycin may potentiate the effect of these anticoagulants. Your doctor should control coagulation parameters (prothrombin time).
• Nelfinavir, zidovudine (medications used to treat HIV infections), as levels of azithromycin in the blood may be increased.
• Fluconazole (medications used to treat fungal infections), as levels of azithromycin in the blood may be increased.
• Terfenadine (a medication used to treat allergies) as the combination may cause heart problems.
• Rifabutin (a medication used to treat pulmonary and non-pulmonary tuberculosis caused by mycobacteria) as it may cause a decrease in white blood cells in the blood.
• Medications with active substances that prolong the QT interval, such as antiarrhythmic class IA (quinidine and procainamide) and class III (dofetilide, amiodarone, and sotalol), cisapride, antipsychotics (such as pimozide), antidepressants (such as citalopram), and antifungals (fluoroquinolones such as moxifloxacin or levofloxacin and chloroquine), as they may cause severe heart rhythm alterations and even cardiac arrest.
