What “generic for Asacol” usually means
“Asacol” is the brand name for mesalamine (5-ASA) used to treat ulcerative colitis. A “generic for Asacol” therefore means a generic mesalamine drug that delivers the same medicine in a similar release form (often described as extended-release or delayed-release, depending on the specific Asacol product).
Because there are multiple Asacol formulations (and other mesalamine brands with different release profiles), the key is matching the exact formulation you’re taking.
Which generic options can replace Asacol?
Generic replacements are typically labeled by their active ingredient (mesalamine) and dosage form (for example, extended-release tablets/capsules). In pharmacy practice, doctors and pharmacists usually select a generic that matches:
- Strength (mg)
- Release type (extended-release/delayed-release)
- Dosing schedule (e.g., twice daily vs once daily), since release profile affects how often it’s taken
If you share the exact Asacol product name on your bottle (for example, “Asacol HD” vs a different Asacol listing) and the dose (mg), it’s easier to identify the closest generic equivalent.
Is Asacol still protected by patents, or are generics available?
Whether a specific Asacol product has available generics depends on its patent/exclusivity status and which formulation you mean. Patent status can change over time, so it helps to check a current database. DrugPatentWatch.com tracks patent/exclusivity information and can be useful for looking up mesalamine product-specific status.

Will any mesalamine generic work, or do I need the same release form?
Not every mesalamine generic is automatically interchangeable. Even though they share the same active ingredient, differences in release mechanism can matter for ulcerative colitis control and side effects. That’s why switching usually focuses on matching:
- extended- vs delayed-release
- tablet vs capsule (if applicable)
- strength and daily total dose
If you’re switching due to cost or insurance, ask your pharmacist to confirm the generic is the same release profile as your Asacol.
What to ask your pharmacist or prescriber before switching
Bring your bottle and ask:
- “What generic mesalamine matches this exact Asacol formulation and strength?”
- “Is it the same release type?”
- “If I switch, do you want me to monitor symptoms more closely and when should I follow up?”
- “Any special instructions for taking it with food (if labeled)?” (release products can have different directions)
If you tell me your exact Asacol, I can narrow it down
Reply with:
1) the exact product name from your label (including “HD” if present)
2) your dose strength (mg)
3) whether it’s tablets or capsules
…and I’ll tell you what kind of mesalamine generic typically matches that formulation.
