Ponstel, with its active ingredient mefenamic acid, is a prescription nonsteroidal anti-inflammatory drug (NSAID) specifically indicated for the relief of moderate pain and primary dysmenorrhea. It functions by inhibiting the body’s production of prostaglandins, hormone-like substances that cause inflammation, pain, and fever. This targeted mechanism makes it a potent option for short-term management of specific inflammatory conditions, offering patients a focused therapeutic approach under medical supervision. It is essential for patients to use this medication exactly as prescribed by their healthcare provider to maximize benefits and minimize risks.
Features
- Active Ingredient: Mefenamic acid (500 mg per capsule)
- Drug Class: Nonsteroidal anti-inflammatory drug (NSAID), fenamate derivative
- Administration: Oral capsule
- Prescription Status: Available by prescription only
- Mechanism of Action: Potent inhibitor of cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis
- Onset of Action: Pain relief typically begins within one to two hours post-administration
- Duration: Generally prescribed for short-term use (not exceeding one week for pain)
Benefits
- Provides effective and rapid relief from moderate pain, particularly associated with menstrual cramps (primary dysmenorrhea)
- Reduces uterine inflammation and contractility by targeting the root cause of prostaglandin excess
- Offers an alternative for patients who may not achieve sufficient relief with other NSAIDs or analgesics
- Helps improve daily functioning and quality of life during menstrual periods by alleviating debilitating pain
- Can be used for other short-term painful inflammatory conditions as determined by a physician
Common use
Ponstel (mefenamic acid) is primarily prescribed for the short-term relief of moderate pain. Its most common and well-established use is in the treatment of primary dysmenorrhea, the medical term for painful menstrual cramps caused by uterine contractions. It is also employed for the relief of other types of acute, non-rheumatic pain, such as musculoskeletal pain, following a healthcare provider’s assessment. Its use is typically limited to a few days, as its safety and efficacy for longer durations have not been established for all conditions.
Dosage and direction
For the treatment of primary dysmenorrhea, the recommended dosage is 500 mg as an initial dose, followed by 250 mg every six hours as needed, usually starting at the onset of bleeding or associated pain. Treatment is typically initiated at the beginning of menstruation and should not exceed a few days. For other painful conditions, the dosage is similar, initiated with a 500 mg dose followed by 250 mg every six hours. It is crucial to take Ponstel with food or milk to minimize the potential for gastrointestinal upset. The total daily dosage should not exceed 1,250 mg. Patients must adhere strictly to the prescribing physician’s instructions regarding duration of therapy.
Precautions
Patients should use Ponstel with caution and under close medical supervision. It is associated with an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may increase with duration of use and in patients with cardiovascular disease or risk factors for it. Ponstel also increases the risk of serious gastrointestinal (GI) adverse events, including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious GI events. Use with caution in patients with fluid retention, hypertension, heart failure, or impaired renal or hepatic function. Avoid use in late pregnancy.
Contraindications
Ponstel is contraindicated in patients with a known hypersensitivity (e.g., anaphylactic reactions, serious skin reactions) to mefenamic acid, aspirin, or other NSAIDs. It should not be used in patients who have experienced asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients. It is contraindicated in the setting of coronary artery bypass graft (CABG) surgery. Use is contraindicated in patients with a history of prostaglandin-sensitive asthma. It is also contraindicated in patients with active peptic ulcer disease or a history of recurrent ulceration/bleeding.
Possible side effect
Common side effects include gastrointestinal disturbances such as dyspepsia, nausea, vomiting, abdominal pain, diarrhea, constipation, and flatulence. Other frequently reported side effects include dizziness, headache, nervousness, and rash. Serious side effects require immediate medical attention and include signs of GI bleeding (e.g., black, tarry stools, vomiting blood), signs of liver problems (e.g., nausea, fatigue, jaundice), signs of heart problems (e.g., chest pain, shortness of breath, weakness in one part of the body), signs of an allergic reaction (e.g., hives, difficulty breathing, swelling of the face or throat), and signs of skin reactions (e.g., red or purple skin rash, blistering, peeling).
Drug interaction
Ponstel can interact with numerous medications, potentially altering their effects or increasing the risk of serious side effects. It may increase the risk of bleeding when used with anticoagulants like warfarin. Concurrent use with other NSAIDs or aspirin is not recommended due to additive risks. It may reduce the antihypertensive effect of ACE inhibitors, angiotensin II receptor blockers, and beta-blockers. It can increase the serum levels and toxicity of lithium and methotrexate. Use with corticosteroids increases the risk of GI ulceration. It may enhance the effects of cyclosporine on the kidneys. Patients must inform their doctor of all medications they are taking, including over-the-counter drugs and supplements.
Missed dose
If a dose is missed, it should be taken as soon as it is remembered. However, if it is almost time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule resumed. Patients should not take a double dose to make up for a missed one. Given that Ponstel is typically used on an as-needed basis for pain, the concept of a “missed dose” is less critical than with chronic medications, but the prescribed dosing interval should still be followed when actively treating pain.
Overdose
Symptoms of overdose may include lethargy, drowsiness, nausea, vomiting, epigastric pain, gastrointestinal bleeding, coma, or acute renal failure. Respiratory depression, seizures, or hypertension may occur. In case of suspected overdose, immediate medical attention must be sought. Management is supportive and symptomatic. There is no specific antidote. Gastric lavage or activated charcoal may be considered if presented soon after ingestion. Forced diuresis, alkalization of the urine, hemodialysis, or hemoperfusion are unlikely to be beneficial due to Ponstel’s high protein binding.
Storage
Store Ponstel capsules at room temperature, between 20°C to 25°C (68°F to 77°F), in a tightly closed container. The medication must be kept out of reach of children and pets. It should be protected from light, moisture, and excessive heat. Do not store it in the bathroom. Properly discard any unused medication after the course of therapy is complete or if it is expired, following local guidelines or through a medicine take-back program.

Reviews
“After years of suffering through debilitating cramps that over-the-counter meds couldn’t touch, my doctor prescribed Ponstel. The difference was night and day. I take it at the first sign of my period, and I can actually function like a normal human being. It’s been a lifesaver.” – Sarah T.
“Effective for my severe menstrual pain, but it does cause some stomach upset for me without food. My doctor warned me about the GI risks, so I make sure to only use it for the 2-3 worst days and always take it with a meal.” – Maria L.
“I was prescribed this for a musculoskeletal injury. It worked well for the pain and inflammation, but I experienced some dizziness. It’s strong and requires a prescription for a reason—you need to be monitored by a doctor while on it.” – James K.
