What is mefenamic acid injection used for?
Mefenamic acid injection is a formulation of the NSAID mefenamic acid (a pain-and-inflammation medicine). Mefenamic acid products are typically used for short-term treatment of pain, including painful conditions such as dysmenorrhea (menstrual pain) and other acute pain states, depending on the specific product label and country.
Is there an injection form of mefenamic acid, or is it usually tablets/capsules?
Mefenamic acid is more commonly marketed as oral tablets/capsules (and sometimes oral suspensions), but some markets may offer injectable or hospital-only formulations. Whether “mefenamic acid injection” is available depends on local approvals and the specific manufacturer’s product.
How is an NSAID injection like mefenamic acid given?
As an injection, it would be administered by a healthcare professional (typically in a clinical setting). The dose, infusion speed (if applicable), and duration depend on the approved product instructions and the patient’s risk factors.
What side effects should patients watch for?
Like other NSAIDs, mefenamic acid can cause side effects such as stomach pain, nausea, heartburn, and diarrhea. More serious but less common risks include gastrointestinal bleeding/ulcers and kidney problems, especially in people with dehydration, older age, or a history of ulcers or kidney disease. Injection products can also cause local reactions at the injection site.
Who should avoid mefenamic acid (or use it only with medical supervision)?
Patients are usually advised to avoid NSAIDs (or use them only under clinician guidance) if they have:
- A history of NSAID allergy or asthma triggered by NSAIDs
- Active peptic ulcer disease or prior serious GI bleeding
- Significant kidney disease
- Uncontrolled heart failure or high cardiovascular risk (depending on local guidance)
- Certain bleeding disorders or use of blood thinners (risk of bleeding)
Drug interactions to consider
NSAIDs can interact with several common medicines, including:
- Blood thinners/antiplatelets (higher bleeding risk)
- Other NSAIDs or corticosteroids (higher GI risk)
- Certain blood pressure medicines and diuretics (possible kidney strain)
- Lithium or methotrexate (NSAID-related toxicity risks in some settings)
Where to check the exact approved injection details?
Because “mefenamic acid injection” can vary by country and manufacturer, the safest way to confirm the exact indications, dosing, and warnings is the product’s regulatory label. If you want, tell me your country (or the manufacturer name printed on the vial/box), and I can help narrow down the likely approved use and precautions.

Which details do you need—use, dosage, or safety?
To give a precise answer, share one of these:
- the strength (e.g., mg/mL) and manufacturer (from the box/vial)
- your country
- what it’s being prescribed for (pain type, menstrual pain, post-op, etc.)
- whether you’re asking as a patient or for clinical use
