Before taking erythromycin with sulfisoxazole, tell your doctor or pharmacist if you are allergic to it; or to other macrolide antibiotics (e.g., azithromycin, clarithromycin) or sulfa medications; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Erythromycin/sulfisoxazole may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that require immediate medical attention. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may affect the heart rhythm (see also Drug Interactions section). Before using erythromycin/sulfisoxazole, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/\"water pills\") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using erythromycin/sulfisoxazole safely.
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
Before having surgery, tell your doctor or dentist that you are taking this medication.

This medication should not be used in children younger than 2 months of age due to the risk of serious side effects.
Caution is advised when erythromycin is used in infants. Although very unlikely, a stomach problem called IHPS (infantile hypertrophic pyloric stenosis) has sometimes occurred. Contact your child\'s doctor immediately if your child has persistent vomiting or increased irritability with feeding.
This medication should be used only when clearly needed during pregnancy. This medication should not be used near the time of delivery because of possible harm to the unborn baby. Discuss the risks and benefits with your doctor.

Therefore, before using erythromycin/sulfisoxazole, report all medications you are currently using to your doctor or pharmacist.

Erythromycin can slow down the removal of other drugs from your body by affecting certain liver enzymes. Some examples of these affected drugs include alfentanil, bromocriptine, buspirone, certain benzodiazepines (alprazolam, midazolam, triazolam), caffeine-containing drugs, cilostazol, corticosteroids (e.g., prednisone), cyclosporine, eplerenone, certain drugs used to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, tadalafil), eszopiclone, felodipine, certain \"statin\" drugs (such as atorvastatin, lovastatin, pravastatin, simvastatin), quetiapine, tacrolimus, theophylline, tolterodine, vinblastine.
Although most antibiotics probably do not affect hormonal birth control such as pills, patch, or ring, some antibiotics may decrease their effectiveness. This could cause pregnancy.
