All your questions answered about Azithromycin
What is Z-Pak (Azithromycin)?
Azithromycin is a macrolide antibiotic that works by stopping the growth of bacteria that cause infections. While it can treat the same bacterial infections as other antibiotics, its shorter course of action makes it a good option.
What bacterial infections can Azithromycin treat?
This prescription antibiotic is used for infections, including those of the ears, lungs, throat, sinuses, reproductive organs, and certain STDs like Chlamydia. The FDA-approved indications for an online Azithromycin prescription include:
- Acute bacterial exacerbations of chronic obstructive pulmonary disease
- Acute bacterial sinusitis
- Community-acquired pneumonia
- Pharyngitis/tonsillitis
- Uncomplicated skin infections
- Urethritis and cervicitis
- Genital ulcer disease
How long does Azithromycin take to work?
This medication usually starts working immediately, but it may take several days for you to actually feel better. Generally, an oral dosage form reaches full concentration in the body within 2 to 3 hours. Completing the course is crucial even if you’re feeling better. If you’ve finished your prescribed course and you’re still not feeling improvement, let your doctor know.
How long does Azithromycin stay in the body?
Azithromycin stays in the body for quite a while after your last dose. Even though you may finish the medication in a few days, the drug leaves the body slowly because it has a long half-life of about 68 hours (almost 3 days). After several half-lives, small amounts can still be present, so the drug may remain in your system for up to 15 days after the final dose.
Why is Azithromycin given for 3 days only?
The standard dose of Azithromycin is 250 mg to 500 mg taken for three to five days once daily. Due to a relatively longer half-life (the time it takes for a drug to be eliminated from the body), it is prescribed for a shorter duration than other antibiotics. For instance, the recommended dosage of Zithromax oral suspension is 10 mg/kg administered orally once daily for 3 days for the treatment of acute otitis media. Higher dosages are reserved for severe infections.
Is Zithromax the same as Azithromycin?
Zithromax is a brand name for Azithromycin (a generic medication). While it is available in the same dosage forms as Azithromycin, it has the distinct advantage of once-daily dosing. You can ask your pharmacist for information regarding Zithromax cost if you have a doctor’s prescription.
How to get a Z-pack online prescription?
The term “Z-Pack” is mostly a U.S. nickname for a specific Azithromycin “dose pack” (often a 5-day course). You’ll typically see Zpack online prescribed and dispensed as azithromycin (generic) or the brand ZITHROMAX tablets. The exact packaging can vary by pharmacy and manufacturer.
How to get Azithromycin for chlamydia?
It’s important to note that Doxycycline is the first-line treatment for chlamydia infections in adults. A single dose of 1 g of Azithromycin for Chlamydia is usually sufficient to alleviate symptoms, versus 100 mg of doxycycline twice daily for 7 days. Your healthcare provider can guide you on whether it’s the right treatment for you.
Can I get an Azithromycin (Z-Pak) prescription over the counter?
No, you cannot legally obtain Azithromycin over the counter. It’s important to contact a certified doctor online to get your prescription according to your symptoms.

Frequently asked questions
How should I prepare for an online Azithromycin appointment?
To prepare for an online doctor visit, gather a few details so the physician can confirm whether an Azithromycin prescription is appropriate. Write down your main symptoms, when they started, and any medication history and allergies. Share any liver disease, heart rhythm problems, or QT-prolonging medications. If you have recently used antibiotics, please note what type and when.
The doctor will ask about your symptoms via text or video chat. This will allow them to prescribe the best course of Azithromycin (Zithromax) and give specific instructions based on your health needs. The physician may request lab tests, recommend a follow-up, or suggest in-person care.
How fast will my online prescription for Azithromycin be ready?
It depends on the virtual care service you are using. With Your Doctors Online, you can get your diagnosis and online prescription in as little as 5 minutes.
What time of day should Z-Pack (Azithromycin) be taken?
It is advisable to take the medication at the same time each day. Usually, the morning time is recommended, as some patients have reported trouble sleeping after taking the pills. The pills should be taken at least 1 hour before food or 2 hours after eating.
What is the Azithromycin dose for adults for a throat infection?
For an adult throat infection caused by group A strep (strep throat), Azithromycin is usually not the first-choice antibiotic. Penicillin or Amoxicillin is typically preferred, and Azithromycin is more often used when someone has a penicillin allergy. When Azithromycin is used for strep throat/pharyngitis/tonsillitis, a common adult regimen is the “Z-Pak” style dosing:
- Day 1: Azithromycin 500mg once
- Days 2–5: Azithromycin 250 mg once daily.
For a throat infection (pharyngitis/tonsillitis) caused by Streptococcus pyogenes, Azithromycin 500 mg daily for 5 days is usually taken.
Is it legal to get Azithromycin online?
Yes, obtaining Azithromycin online is legal when prescribed through a licensed healthcare provider. According to the FDA, non-controlled substances can be prescribed through telehealth without an initial in-person visit.
Should I stop taking Azithromycin once I feel better?
No, you should always finish the full prescribed course of Azithromycin unless your physician tells you otherwise. Even if your symptoms improve after a couple of days, continue taking all doses for the recommended duration. Stopping an antibiotic early can lead to the infection not being fully treated, allowing the remaining bacteria to develop resistance to the antibiotic.
What are some alternatives to Azithromycin for treating sinus infections?
Your doctor may prescribe the following antibiotics for sinus infections:
- Doxycycline (Vibramycin, Doryx)
- Amoxicillin-clavulanate (Augmentin)
- Amoxicillin (Amoxil)
Always consult your physician to determine a personalized treatment plan based on your allergy profile and the specific infection.
Azithromycin vs Amoxicillin: Which is better?
Both are effective antibiotics, but Azithromycin offers broader coverage and a shorter treatment course (5 days vs. 7–10 days). Amoxicillin is the preferred option for strep throat and other common infections. Azithromycin is a safe alternative for penicillin-allergic patients, though rising resistance has shifted first-line treatment back toward Amoxicillin. In a nutshell, it depends on your conditions and body composition to determine which antibiotic prescription is better for you.
What are some other antibiotic medications?
Our doctors treat many bacterial infections and provide an online antibiotic prescription for:
