About Ponstel

Ponstel is a prescription-only non-steroidal anti-inflammatory drug (NSAID) that contains the active ingredient mefenamic acid. It belongs to the anthranilic acid class of NSAIDs and is commonly prescribed for short-term relief of mild to moderate pain, including dysmenorrhoea, dental pain, musculoskeletal aches and inflammatory conditions. While the medication is available in 250 mg and 500 mg oral tablets, it should be used under the guidance of a qualified healthcare professional, especially in Singapore where it is listed as a prescription medicine.

What is Generic Ponstel (Mefenamic Acid)?

Generic Ponstel (Mefenamic Acid) is an NSAID that works by inhibiting the cyclo-oxygenase (COX) enzymes involved in prostaglandin synthesis. By reducing prostaglandin production, the drug diminishes inflammation, lowers fever, and alleviates pain. Approved by the Health Sciences Authority (HSA) of Singapore, it is indicated for short-term management of acute pain and menstrual cramps. The medication is supplied as film-coated tablets in strengths of 250 mg and 500 mg.

How Ponstel Works

Mefenamic acid blocks both COX-1 and COX-2 isoforms, leading to a decrease in prostaglandin E2, prostacyclin, and thromboxane A2. These mediators normally sensitize nerve endings and promote vasodilation at sites of tissue injury. By curbing their production, Ponstel reduces peripheral sensitisation and the associated pain signal transmission. The drug is rapidly absorbed from the gastrointestinal tract, reaching peak plasma concentrations within 2-4 hours. It is extensively bound to plasma proteins (≈99 %) and undergoes hepatic metabolism primarily via glucuronidation, with metabolites eliminated in the urine. The onset of analgesia is usually observed within 30 minutes, and the duration of effect lasts 4-6 hours, which explains the need for multiple daily doses for continuous pain control.

Why Ponstel Is Used for Pain Relief

  • Acute Musculoskeletal Pain: By dampening inflammation at the injury site, Ponstel provides faster relief than paracetamol alone, making it a preferred option when inflammation is a dominant component.
  • Dysmenorrhoea: Prostaglandins drive uterine contractions during menstruation. Inhibiting their synthesis reduces uterine hyper-contractility, alleviating menstrual cramps effectively.
  • Dental and Post-operative Pain: The drug’s ability to tackle both inflammation and nociceptive signals makes it suitable after dental extractions or minor surgical procedures.
  • Headache/Migraine Adjunct: While not first-line, some clinicians use low-dose Ponstel as an adjunct to triptans when a vascular component is suspected.

In Singapore’s clinical guidelines, mefenamic acid is positioned as a second-line NSAID after ibuprofen or naproxen, primarily because it carries a higher risk of gastrointestinal irritation. Nevertheless, its rapid onset and efficacy for dysmenorrhoea keep it in regular use.

Off-Label and Investigational Uses of Ponstel

Limited peer-reviewed studies have explored mefenamic acid for migraine prophylaxis and for certain inflammatory eye conditions. These investigations are small-scale and have not led to regulatory endorsement in Singapore. Off-label use should only be considered under the supervision of a qualified healthcare provider.

Is Ponstel Right for You?

Ponstel is appropriate for adults who require short-term pain relief and have no contraindications such as active peptic ulcer disease, severe renal or hepatic impairment, or known hypersensitivity to anthranilic-acid NSAIDs. Elderly patients may experience heightened gastrointestinal risk and should use the lowest effective dose for the shortest duration. The drug is not recommended during pregnancy, especially in the third trimester, due to potential effects on the fetal cardiovascular system. Patients with asthma that is exacerbated by NSAIDs should avoid Ponstel. Always verify that your medical history aligns with the prescribing information before initiating therapy.

Taking Ponstel Effectively

  • Dosage: For most indications, start with 250 mg after meals and repeat every 4-6 hours as needed. Do not exceed 150 mg per day for acute pain.
  • Food Interaction: Taking the tablet with food or a glass of milk reduces gastric irritation.
  • Missed Dose: If you forget a dose and it is within 6 hours of the scheduled time, take it immediately; otherwise, skip it and resume your regular schedule. Do not double-dose.
  • Travel Tips: Carry a copy of the prescription and keep tablets in their original packaging to avoid customs delays.

Understanding Side Effects and How to Manage Them

  • Gastrointestinal Distress (nausea, dyspepsia, ulcer risk): These arise from COX-1 inhibition in the gastric mucosa. Mitigate by taking Ponstel with meals, using a proton-pump inhibitor if prescribed, and avoiding alcohol or smoking.
  • Renal Effects (reduced renal perfusion, creatinine rise): Occur due to diminished prostaglandin-mediated vasodilation in the kidneys. Patients with chronic kidney disease should be monitored closely or choose an alternative analgesic.
  • Dermatologic Reactions (rash, photosensitivity): Promptly discontinue and seek medical advice if a rash spreads or is accompanied by fever.
  • Serious Events (gastrointestinal bleeding, myocardial infarction, stroke): Though rare with short-term use, any sudden severe abdominal pain, black stools, chest discomfort, or neurological deficits warrants immediate emergency care.

Frequently Asked Questions

  • Can I take Ponstel with other NSAIDs? Combining Ponstel with another NSAID (e.g., ibuprofen) increases the risk of gastrointestinal bleeding and should be avoided unless explicitly directed by a physician.

  • How long is it safe to use Ponstel for menstrual cramps? Ponstel is intended for short-term use; most clinicians recommend a maximum of 3 days of treatment per menstrual cycle to limit ulcer risk.

  • Is it okay to take Ponstel while on anticoagulants? Mefenamic acid can potentiate the antiplatelet effect of warfarin or direct oral anticoagulants, raising bleeding risk. Close monitoring of INR or alternative analgesia is advisable.

  • What should I do if I experience stomach pain after a dose? Mild dyspepsia can be managed with food and antacids. Persistent or severe abdominal pain may indicate an ulcer and requires prompt medical evaluation.

  • Can Ponstel be used in patients with asthma? Some individuals with aspirin-exacerbated respiratory disease react to NSAIDs, including mefenamic acid. If you have asthma that worsens after NSAID exposure, avoid Ponstel.

  • Does Ponstel interact with alcohol? Alcohol can irritate the gastric lining and amplify the ulcerogenic potential of Ponstel. Limiting or avoiding alcohol during treatment is recommended.

  • Is it safe to take Ponstel during breastfeeding? Mefenamic acid passes into breast milk in low concentrations. While occasional short-term use is unlikely to harm a nursing infant, prolonged exposure should be discussed with a pediatrician.

  • Why does my urine appear darker after taking Ponstel? Rarely, mefenamic acid metabolites may cause a temporary discoloration of urine. This effect is benign and resolves after discontinuation.

  • Can I switch from brand Ponstel to a generic version? Yes. Generic mefenamic acid tablets contain the same active ingredient and are bioequivalent, offering a cost-effective alternative without compromising efficacy.

  • How should I store Ponstel? Keep tablets in a dry place at room temperature, away from direct sunlight and out of reach of children.
