Piperacillin/tazobactam cost?

The cost of piperacillin/tazobactam (e.g., Zosyn or generics) varies a lot based on country, brand vs generic, vial size, and whether you’re buying cash vs through insurance/hospital contracts.

Quick ballpark (common in the US)

• Generic piperacillin/tazobactam (hospital vial, typical 4.5 g): often ~$50–$150 per dose, but it can be higher depending on supplier and contracted pricing.
• Brand Zosyn can be significantly more (sometimes ~2× or more).
• Total course cost depends on dosing frequency (commonly every 6–8 hours) and duration.

To give you a more accurate estimate

Tell me:

1. What country/state are you in?
2. Brand or generic (Zosyn vs piperacillin/tazobactam)?
3. Dose/vial size (commonly 4.5 g or 3.375 g)
4. Is this for one-time use, or an estimated treatment course?

If you share those, I can narrow it down to a realistic range and help you find the most cost-effective option.
