Description
What is Celecoxib 100 mg?
Celecoxib 100 mg is an oral medication in the NSAID family (nonsteroidal anti-inflammatory drugs). It’s often referred to as a COX-2 selective NSAID, meaning it primarily targets an enzyme involved in pain and inflammation.
In the United States, celecoxib is commonly prescribed to help manage pain and stiffness from inflammatory conditions. If you’re exploring additional pain-care options, you can also browse the pain relief category here: pain
How it works (simple)
Celecoxib reduces pain and inflammation by blocking cyclooxygenase-2 (COX-2), an enzyme the body uses to make prostaglandins (chemical messengers involved in swelling, pain, and inflammation).
While COX-2 selectivity may reduce certain stomach side effects compared with some non-selective NSAIDs, serious GI bleeding can still occur especially at higher doses or with longer use.
Uses / What it’s commonly prescribed for
Healthcare providers may prescribe celecoxib for:
- Osteoarthritis pain and stiffness
- Rheumatoid arthritis symptoms
- Ankylosing spondylitis pain and inflammation
- Acute pain (short-term use in select cases)
- Primary dysmenorrhea (menstrual cramps)
Your clinician will decide if a celecoxib 100 mg capsule is appropriate based on your history (especially heart, stomach, kidney, or bleeding risks).
How to take / use directions (general)
Follow your licensed healthcare provider’s directions and the prescription label. General guidance often includes:
- Take by mouth with water, usually once or twice daily depending on the condition.
- You may take it with or without food take it with food if it upsets your stomach.
- Swallow capsules whole unless your pharmacist/provider gives specific alternate instructions.
- Use the lowest effective dose for the shortest duration appropriate for your condition (common NSAID safety principle).

- Blood thinners/anticoagulants (e.g., warfarin) and antiplatelets (bleeding risk)
- Other NSAIDs (e.g., ibuprofen/naproxen) or high-dose aspirin (more GI risk)
- SSRIs/SNRIs (may increase bleeding risk)
- ACE inhibitors/ARBs and diuretics (may worsen kidney function in some people)
- Lithium or methotrexate (levels/effects may increase)
- CYP2C9 inhibitors (e.g., fluconazole) may raise celecoxib levels inducers (e.g., rifampin) may lower effect.
Alcohol: Can increase the risk of stomach irritation/bleeding use caution and ask your provider.
