Product Overview

Introduction of Panadol Extend SR 665mg Caplet 48s

Panadol Extend SR 665mg Caplet is a trusted over-the-counter analgesic and antipyretic belonging to the non-opioid pain reliever drug class, formulated with paracetamol (acetaminophen) as its active ingredient in a unique sustained-release (SR) formula. What makes this caplet stand out is its dual-layer technology — one layer works quickly while the other releases gradually over time, giving you longer-lasting relief in a single dose. Like all medicines, it's important to know that some people may experience side effects such as nausea, skin rash, liver-related reactions, or allergic responses, so it should always be taken responsibly and within the recommended dose. If you have liver concerns, regularly consume alcohol, or are already taking other paracetamol-containing products, this is something you'll want to discuss with your pharmacist or doctor before starting. Rest assured, when used correctly, Panadol Extend is a well-established and widely trusted option available at licensed pharmacies across Malaysia, including online.

How to Take Panadol Extend SR 665mg Caplet
Panadol Extend SR 665mg Caplets should be swallowed whole with a full glass of water — do not crush, chew, or break the caplet, as doing so will destroy the sustained-release mechanism and may lead to unintended rapid absorption of the full dose. It is best taken with or without food, though taking it with food may help if you have a sensitive stomach. Always follow the dosage instructions on the packaging or as directed by your healthcare professional, and never take more than the recommended amount within a 24-hour period.

Dosage of Panadol Extend SR 665mg Caplet
The generally recommended dose for adults and adolescents aged 12 years and above is 2 caplets (1,330mg) up to 3 times daily, with a minimum interval of 6 to 8 hours between doses, not exceeding 6 caplets (3,990mg) in any 24-hour period. Always adhere to the lowest effective dose for the shortest duration necessary, and consult a pharmacist or doctor if you are unsure about the right dose for your individual needs.

Shelf Life of Panadol Extend SR 665mg Caplet
Panadol Extend SR 665mg Caplets typically have a shelf life of 3 years from the date of manufacture when stored under the recommended conditions. Always check the expiry date printed on the outer packaging or blister strip before use, and do not consume the product if it has passed its expiry date, even if the caplets appear unchanged in appearance.

How to Store Panadol Extend SR 665mg Caplet

  • Store Panadol Extend SR 665mg Caplets in a cool, dry place below 30°C, away from direct sunlight, heat, and moisture.
  • Keep the product in its original packaging with the blister strips intact to protect the caplets from environmental exposure.
  • Ensure this medicine is stored out of reach and sight of children at all times, and do not store it in the bathroom or near the kitchen sink where humidity levels tend to be higher.

⚠️ Important: Liver damage is the most serious risk associated with paracetamol overdose. Never exceed the recommended daily dose. Seek immediate medical attention if you suspect an overdose, even if you feel well.

Contraindications of Panadol Extend SR 665mg Caplet
Panadol Extend SR 665mg Caplet is contraindicated (should not be used) in the following situations:

  • Known hypersensitivity or allergy to paracetamol, acetaminophen, or any of the excipients in the formulation
  • Severe hepatic impairment or active liver disease, including conditions such as hepatitis or cirrhosis
  • Severe renal impairment — use with caution or avoid unless directed by a doctor
  • Chronic or heavy alcohol use — significantly increases the risk of paracetamol-induced liver toxicity
  • Children under 12 years of age — this specific formulation and strength is not intended for paediatric use
  • Concurrent use of other paracetamol-containing products — taking multiple paracetamol products simultaneously can lead to accidental overdose
  • Patients with Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency — use with caution and only under medical supervision

Always inform your doctor or pharmacist of your full medical history and current medications before starting this product.

Drug & Food Interactions of Panadol Extend SR 665mg Caplet
Being aware of potential interactions helps you use this medicine safely. Here are the key interactions to note:

Drug Interactions:

  • Warfarin and other anticoagulants — Regular or high-dose paracetamol use may enhance the anticoagulant effect, increasing the risk of bleeding; INR monitoring may be required
  • Isoniazid (TB medication) — May increase the risk of paracetamol-induced liver toxicity
  • Carbamazepine, phenytoin, phenobarbital (anticonvulsants) — These enzyme-inducing drugs may reduce paracetamol efficacy and increase the risk of liver damage
  • Rifampicin — May reduce the effectiveness of paracetamol and increase hepatotoxicity risk
  • Cholestyramine — May reduce the absorption of paracetamol if taken within one hour of this product
  • Metoclopramide and domperidone — May increase the rate of paracetamol absorption
  • Other NSAIDs or analgesics — Concurrent use should be discussed with a healthcare professional to avoid compounding side effects
  • Probenecid — May inhibit paracetamol metabolism, potentially increasing its concentration in the body

Food & Lifestyle Interactions:

  • Alcohol — Consuming alcohol while taking paracetamol significantly raises the risk of liver damage; avoid alcohol during treatment
  • High-fat meals — May slightly delay the absorption of paracetamol but are not considered clinically significant for most users
  • Fasting or malnutrition — Individuals who are malnourished or have low glutathione reserves may be at higher risk of liver toxicity even at standard doses

💡 Always inform your pharmacist or doctor about all medications, supplements, and herbal products you are currently taking before using this product.

Quick Tips for Panadol Extend SR 665mg Caplet

  • Always swallow the caplet whole — never crush, split, or chew it, as this destroys the sustained-release mechanism
  • Check all your other medications for paracetamol content before taking this product to avoid accidental double-dosing
  • Set a timer or reminder to maintain the correct 6–8 hour gap between doses
  • Store in a cool, dry place away from sunlight, heat, and humidity — avoid storing in bathrooms or car gloveboxes
  • Keep out of reach of children at all times — store in a locked or elevated cabinet if possible
  • Do not exceed 6 caplets in 24 hours — more is not better and can be harmful to your liver
  • Check the expiry date before every use, especially if the pack has been stored for a while
  • Dispose of expired or unused medicine responsibly — return to a pharmacy for proper disposal rather than flushing or throwing in general waste
  • Avoid alcohol during the course of treatment to protect your liver
  • Purchase from a licensed pharmacy — whether in-store or online — to ensure you receive a genuine, properly stored product
  • Consult a pharmacist or doctor if your symptoms do not improve within 3 days or worsen at any point
