For adults, the typical Zithromax (azithromycin) dosage for a sinus infection is 500 mg on the first day, followed by 250 mg daily for four more days. This is a total of 1.5 grams of medication over five days.
Children’s dosages vary significantly based on weight. Always follow your doctor’s prescription precisely. Never administer medication based on information found online; consult a medical professional for the correct dosage for your child.
Common side effects include nausea, diarrhea, and vomiting. Severe allergic reactions are rare but possible; seek immediate medical attention if you experience symptoms like difficulty breathing or swelling of the face, lips, or tongue.
Zithromax is an antibiotic; it fights bacterial infections but not viral ones. If your sinus infection is viral, this medication will be ineffective. A doctor will determine the cause of your infection.
Finish the entire course of antibiotics, even if symptoms improve before the medication is completed. Stopping early could lead to a recurrence of the infection or antibiotic resistance.
Always inform your doctor about any other medications you are currently taking, including over-the-counter drugs and herbal remedies, to avoid potential drug interactions.
