Generic Ponstel (Mefenamic Acid)

Introduction

Ponstel contains the non-steroidal anti-inflammatory drug (NSAID) mefenamic acid. It is supplied as oral tablets in strengths of 250 mg and 500 mg. Mefenamic acid belongs to the anthranilic acid class of NSAIDs and is primarily used for the short-term relief of mild-to-moderate pain associated with musculoskeletal inflammation, dental procedures, and dysmenorrhea. The medication is marketed in many countries under brand names such as Ponstel, Anaprox, and Meftal. In addition to its approved uses, clinicians sometimes employ mefenamic acid off-label for conditions such as postoperative pain or migraine, but such practices are not formally endorsed by regulatory agencies.

What is Ponstel?

Ponstel is a tablet formulation that delivers the active ingredient mefenamic acid, a synthetic anthranilic-acid NSAID. It was first introduced in the s and is now produced by several generic manufacturers worldwide. The product is classified as an analgesic/anti-inflammatory medication. While Ponstel is a brand name, the tablets sold through our pharmacy are a generic version of mefenamic acid that meets the same quality standards as the reference products.

How Ponstel Works

Mefenamic acid inhibits the cyclo-oxygenase enzymes COX-1 and COX-2, which are essential for converting arachidonic acid into prostaglandins. Prostaglandins amplify inflammation, pain, and fever. By reducing prostaglandin synthesis, Ponstel decreases peripheral sensitisation of nociceptors and lowers the inflammatory response at the site of injury. The drug reaches peak plasma concentrations within 2-4 hours after oral intake, and its half-life is approximately 2 hours; therapeutic effects typically last 4-6 hours, necessitating repeat dosing for sustained relief.

Conditions Treated with Ponstel

• Acute Musculoskeletal Pain - Disorders such as sprains, strains, and tendonitis generate prostaglandin-mediated inflammation. COX inhibition alleviates pain and swelling.
• Dental Pain - Post-extraction or orthodontic discomfort responds well to short courses of mefenamic acid because of its rapid onset.
• Dysmenorrhea (Menstrual Cramps) - Prostaglandins drive uterine contractions; Ponstel reduces the intensity of cramping in many women.

These indications are approved by major regulators (e.g., U.S. FDA, European Medicines Agency) based on clinical trials demonstrating efficacy comparable to other short-acting NSAIDs.

Off-Label and Investigational Uses of Ponstel

• Migraine Attacks - Small open-label studies have reported that a single 500 mg dose of mefenamic acid can alleviate mild migraine headache within an hour. Formal approval is lacking, and evidence remains limited.
• Post-operative Analgesia - Some surgeons prescribe mefenamic acid as part of multimodal pain control after minor outpatient procedures. Controlled trials are sparse, and safety in the immediate postoperative period must be assessed case-by-case.

These applications are not sanctioned by the FDA or EMA. Patients should discuss any off-label consideration with a qualified healthcare professional.

Is Ponstel the Right Medication for You?

Ponstel is appropriate for adults who need short-term relief of acute inflammatory pain and who have no contraindications to NSAIDs. It is frequently chosen when rapid analgesia is desired and when a short treatment course (≤ 7 days) is sufficient.

Contraindications include:

• Known hypersensitivity to mefenamic acid or other anthranilic-acid NSAIDs.
• Active peptic ulcer disease or gastrointestinal bleeding.
• Severe renal or hepatic impairment.
• Third-trimester pregnancy (risk of premature closure of the ductus arteriosus).

Patients with cardiovascular disease, asthma exacerbated by NSAIDs, or those taking anticoagulants should use Ponstel only after a professional risk-benefit assessment.

Risks, Side Effects, and Interactions

Common

• Gastro-intestinal discomfort (epigastric pain, dyspepsia).
• Headache or dizziness.
• Nausea or mild vomiting.
• Edema (especially in the lower extremities).

Rare

• Photosensitivity reactions (sunburn-like rash).
• Elevated liver enzymes indicating mild hepatic stress.
• Renal function changes (increased serum creatinine).

Serious

• Peptic ulcer perforation or gastrointestinal bleeding - may present as melena, hematemesis, or severe abdominal pain.
• Severe hypersensitivity (anaphylaxis, Stevens-Johnson syndrome).
• Cardiovascular thrombotic events (myocardial infarction, stroke) in patients with existing risk factors.

Drug-Drug Interactions

• Anticoagulants/antiplatelet agents (warfarin, clopidogrel) - increased bleeding risk.
• Selective COX-2 inhibitors - additive renal and gastrointestinal toxicity.
• Lithium - NSAIDs may raise serum lithium levels; monitor closely.
• Methotrexate - reduced clearance may lead to toxicity.

Drug-Food Interactions

• Alcohol - synergistic irritation of the gastric mucosa; avoid concurrent heavy intake.
• High-salt or high-protein meals - may modestly delay absorption but do not affect overall efficacy.

Patients should always inform their prescriber about over-the-counter products, herbal supplements, or dietary habits that could influence Ponstel’s safety profile.

Use: Dosing, Missed Dose, Overdose

• Standard dosing for adults: 250 mg taken orally every 4-6 hours as needed, not to exceed 1 g per day. For dysmenorrhea, a typical regimen is 500 mg three times daily for the first 2-3 days of menstrual flow.
• Missed dose - If a scheduled dose is forgotten and the interval is less than 12 hours, take the missed tablet immediately. If more than 12 hours have passed, skip the missed dose and resume the regular schedule; do not double-dose.
• Overdose - Symptoms may include severe nausea, vomiting, abdominal pain, and dizziness. Seek emergency medical attention; activated charcoal may be administered if presentation is early. Supportive care and monitoring of renal and hepatic function are standard.
• Administration guidance - Take tablets with a full glass of water. Food can lessen gastrointestinal irritation; however, for rapid analgesia a dose on an empty stomach is acceptable. Avoid alcohol while taking Ponstel and refrain from operating heavy machinery if dizziness occurs.

FAQ

• What should I do if I experience stomach pain after taking Ponstel? If the pain is mild, take the medication with food or an antacid and monitor. Persistent or severe abdominal pain, especially if accompanied by black stools, requires immediate medical evaluation.

• Can I travel internationally with Ponstel tablets? Yes. Store the medication in its original packaging, keep it in your carry-on bag, and carry a copy of the prescription or a doctor’s note if required by customs.

• How long can I store Ponstel before it expires? Tablets remain stable for up to 24 months when kept in a dry, room-temperature environment away from direct sunlight. Check the printed expiry date on the blister pack.

• What inactive ingredients are present in Ponstel tablets? Common excipients include microcrystalline cellulose, lactose monohydrate, magnesium stearate, and a coating polymer. Patients with lactose intolerance should verify the exact formulation from the supplier.

• Is Ponstel safe for people with asthma? Patients with aspirin-sensitive asthma may react to mefenamic acid. A prior reaction to any NSAID warrants avoidance of Ponstel unless a specialist confirms safety.

• Will Ponstel appear on a standard drug test? Routine employment drug screens do not target NSAIDs, so Ponstel is unlikely to be detected. Specialized forensic testing would be required to identify the compound.

• Do I need to adjust the dose if I have reduced kidney function? In moderate renal impairment, the maximum daily dose should be reduced to 500 mg, and treatment duration should be limited. Severe renal failure generally contraindicates use.

• Can I take Ponstel together with a hormonal contraceptive? Mefenamic acid does not interfere with the efficacy of combined oral contraceptives. However, gastrointestinal upset may affect absorption of oral hormones; taking the contraceptive at a different time of day can minimise this risk.

• Is there any benefit to chewing Ponstel tablets? The tablets are designed for swallowing whole. Chewing may increase gastric irritation and alter the intended release profile, reducing tolerability.

• Why does Ponstel cause menstrual cramps to improve faster than other NSAIDs? Mefenamic acid has a relatively high affinity for COX-1 and COX-2, leading to rapid suppression of uterine prostaglandin production. Clinical studies have shown comparable or slightly faster onset of relief versus ibuprofen for dysmenorrhea.

• Can I use Ponstel while fasting for religious observances? If gastrointestinal irritation is a concern, it is advisable to take the tablet with a small amount of food or milk to protect the stomach lining, even during fasting periods.

• What is the difference between Ponstel and generic mefenamic acid? Chemically they are identical; the distinction lies in branding, packaging, and price. The generic supplied by our pharmacy adheres to the same pharmacopeial standards as the branded product.
