• Have liver problems, your doctor may need to monitor your liver function or discontinue treatment.
• During treatment with this medication, your skin and/or the white of your eyes turns yellow, inform your doctor immediately, as it may be a symptom of a serious liver disease (which can be fatal).

• You know that you have a slow or irregular pulse or reduced cardiac function: azithromycin is not recommended.
• You are taking medications known as antiarrhythmics (used to treat abnormal heart rhythm), cisapride (used to treat stomach problems) or terfenadine (an antihistamine used to treat allergies): azithromycin is not recommended.
• You have a disease called myasthenia gravis, with muscle weakness and fatigue, as this medication may contribute to worsening the symptoms of this disease or triggering it.

If you experience severe and persistent diarrhea, especially with blood or mucus, during or after treatment, consult your doctor immediately.

Azitromicina may interact with other medications.Inform your doctor or pharmacist if you are taking any of the following medications:

• Antacids. If you are taking antacids (such as aluminum hydroxide) and Azitromicina Alter, it is recommended to avoid simultaneous administration of both medications at the same time of day: take azithromycin at least 1 hour before or 2 hours after taking an antacid.

• Ergot derivatives, for example, ergotamine (used to treat migraines): Do not administer at the same time as it may develop ergotism (a potentially serious adverse effect with numbness or tingling in the extremities, muscle cramps, headaches, convulsions, or abdominal or chest pain).

• Cumarin derivatives, for example, warfarin (used to prevent blood coagulation): may increase the risk of bleeding.

• Digoxin (used to treat heart failure and arrhythmias): may increase digoxin levels in the blood.

•Colchicine (used to treat gout and familial Mediterranean fever)

• Zidovudine, nelfinavir (used in HIV treatment): zidovudine or azithromycin levels may increase.

• Rifabutin (used in HIV and bacterial infections, including tuberculosis): may occur a decrease in the number of white blood cells in the blood.

• Cyclosporine (an immunosuppressant used after organ transplantation): cyclosporine levels may increase. Your doctor will need to monitor your cyclosporine levels in the blood.

• Cisapride (used to treat stomach problems): may cause heart problems.

• Astemizole, terfenadine (antihistamines used to treat allergic reactions), their effects may be increased.

• Alfentanil (sedative): the effect of alfentanil may increase.

•Fluconazole (for fungal infections): azithromycin levels may be reduced. • Amiodarone, propafenone (medications for treating ventricular and supraventricular tachycardias).

No interactions have been observed between azithromycin and cetirizine (an antihistamine); didanosine, efavirenz, indinavir (for HIV infection); atorvastatin (for cholesterol and heart problems); carbamazepine (for epilepsy), cimetidine (an antacid); methylprednisolone (to suppress the immune system); midazolam, triazolam (sedatives); sildenafil (for impotence), theophylline (for asthma) and trimethoprim/sulfamethoxazole (a combination antibiotic).

If you take medications that prolong the QT interval, do not take this medication.

Pregnancy, breastfeeding, and fertility

There is not enough information on the use of azithromycin in pregnant women. Therefore, azithromycin is not recommended during pregnancy and breastfeeding, unless, at the doctor's discretion, the benefit outweighs the risk to the fetus.

Azithromycin has been reported to pass into breast milk, but there are no adequate and well-controlled studies in lactating women that have revealed how azithromycin passes into breast milk. Therefore,azithromycin is not recommended during pregnancy and breastfeeding, unless, at the doctor's discretion, the benefit outweighs the risk to the child.

Driving and operating machinery

There is no evidence that Azitromicina Alterhas an effect on the ability to drive or operate machinery.However, due to the fact that during treatment with azithromycin, cases of drowsiness and dizziness have been reported, the patient should exercise caution when driving or operating machinery, until it is established how azithromycin may affect them individually.
