ZITHROMAX (Z-PACK)—Information, Dosage, Cost, How to Get a Prescription

January 21, 2021

Azithromycin (Zithromax, also known as Z-pack) is an antibiotic—a medication for fighting bacteria. It belongs to the macrolide family of antibiotics, which work by binding to bacterial ribosomes. Ribosomes are cellular components for making proteins. Stopping the cell from making protein stops cellular growth and reproduction, ending infection. This antibiotic is effective against a wide array of bacterial species and types of infection. It is used against certain eye infections, bronchitis, pneumonia, skin infections, sexually transmitted diseases (particularly chlamydia), sinusitis, throat infections, ear infections, Lyme disease, and urinary tract infections. Azithromycin works quickly, allowing patients often to feel better one day after beginning treatment, and able to return to work or school after 3 days.


Azithromycin is available as oral tablets or solution. The usual dose is 250-500 once a day. The Z-pack contains the 6 pills which are taken over a period of usually 5 days (500 mg on day 1 followed by 250 mg daily on day 2-5).
