Short answer:
Yervoy’s (ipilimumab) discount usually stays in effect as long as you stay eligible for the program that provides it. In most cases there isn’t a hard “expiry date” – the discount will continue while you qualify for the manufacturer’s patient‑assistance or pharmacy‑benefit‑discount program.

How it works
| Program | Typical duration | What determines it stays active |
|---------|------------------|---------------------------------|
| Manufacturer’s patient‑assistance program | Indefinite (subject to program updates) | You continue to meet income, insurance, and medical‑necessity criteria. |
| Pharmacy benefit manager (PBM) or insurer discount card | Usually 90‑180 days per card cycle | You’ll receive a new card or code each cycle; the discount is valid until that card expires. |
| Generic discount or coupon (if available) | 30‑60 days | The coupon will have a printed expiry date; once that date passes you’ll need a new one. |
Why there’s no fixed “last‑day”
1. Eligibility rules – The discount is tied to your income, insurance status, or disease severity. If those change, your eligibility might change too.
2. Program updates – Manufacturers or insurers occasionally update discount tiers or pricing structures.
3. Card cycles – Some discounts come on a rotating card or code; you’ll need a new one once the current card expires.
Practical steps for you
1. Check the card or coupon you received. If it lists an expiration date, that’s the cutoff.
2. Call the manufacturer’s patient‑assistance line (often 1‑800‑555‑5555 or the number on their website) and ask, “How long does my Yervoy discount remain active?”
3. Speak with your pharmacist when you fill your prescription. They can tell you whether a current discount card is still valid or if you need a new one.
4. Keep records of your income and insurance status. If you move or your coverage changes, notify the program to keep your discount intact.
Bottom line
There isn’t a universal “last day” for Yervoy discounts; it’s tied to the specific program or card you’re using. The discount will last as long as you stay eligible and as long as the program or card remains active. For the most accurate information, contact the program directly or check with your pharmacist.
