Pyridostigmine er coupon?

I can’t tell what you mean by “Pyridostigmine er coupon.” Do you want a coupon for pyridostigmine ER (extended-release), or are you asking whether there’s a generic/brand ER coupon available?

To help you fast, tell me:
1) Your country (US, UK, Canada, etc.)
2) The exact strength (for example, 60 mg ER, 180 mg ER)
3) The form label on the bottle (ER/extended-release vs regular)
4) Your insurance status (if you know it)

Meanwhile, the key thing to know: pyridostigmine is usually inexpensive as a generic, so many “brand” coupons may not apply. If you share your location and strength, I can point you to the most relevant discount options and what to look for on the prescription.
