Short answer

Azithromycin, often sold as a Z-Pak, may be prescribed during pregnancy when an infection needs treatment, but it should be used only for a clinician-confirmed bacterial infection.

Use only when prescribed

What is the safest way to think about this?

MotherToBaby updated its azithromycin fact sheet in 2026 and notes that most studies have not found an increased chance of birth defects, while NHS guidance says it can be used in pregnancy when an infection needs treatment. The practical answer is still prescription-led because antibiotic choice depends on the infection.

What is generally okay?

  • Take azithromycin only if it was prescribed for your current infection.
  • Tell your clinician about heart rhythm problems, liver disease, medication interactions, or antibiotic allergies.
  • Ask what symptoms should improve and when to call back if they do not.

What should you avoid or double-check?

  • Avoid leftover Z-Pak tablets or antibiotics borrowed from someone else.
  • Avoid using azithromycin for viral colds, flu, or COVID symptoms.
  • Avoid skipping doses or stopping early unless your clinician changes the plan.

How SafeMama helps

SafeMama can flag azithromycin, Zithromax, Z-Pak, macrolide antibiotics, and combination medicine labels so users can confirm the exact ingredient with a clinician or pharmacist.

Open the SafeMama app, scan the barcode or search the ingredient, then use the result as a starting point for a conversation with your healthcare provider.

Frequently asked questions

Is a Z-Pak the same as azithromycin?

Yes. Z-Pak is a common brand/package name for azithromycin tablets, but always check the prescription label and dose schedule.

Can untreated infection be worse than taking an antibiotic?

Sometimes yes. In pregnancy, untreated bacterial infections can matter, so the decision should weigh infection risk against medicine exposure with a clinician.

Can I take azithromycin for a cold while pregnant?

No antibiotic treats a viral cold. Ask your clinician if symptoms suggest a bacterial infection or another condition that needs treatment.
