➦ Onset Of Action
- Time for absorption:
Usually, after intake, the medicine is broken down, releasing the generic element within 15 to 20 minutes.
This work is done mostly by the gastric juices in the stomach.
- Initial effects:
After taking the medicine, it helps to bring pain relief within 30 to 60 minutes.
- Peak plasma concentration:
The effects of paracetamol are highest in your blood after 1 to 2 hours of taking the medicine.
- Lasting time:
The effects of a single dose last for about 4 to 6 hours.
How Does Calpol 650mg Work?
Calpol 650 Mg works by blocking the production of certain chemicals in the body that cause pain and fever. This helps lower body temperature and provides pain relief.
It works by blocking chemical messengers in the brain that cause pain and fever, helping to lower body temperature and reduce discomfort.
➦ For Relieving Pain
- The Factor:
Paracetamol is known as a mild inhibitor of an enzyme referred to as Cyclooxygenase (COX-1 & COX-2).
Calpol, by inhibiting the activity of these enzymes, interferes with the production of prostaglandins.
- The Effect:
This results in reduced concentration of prostaglandins in the brain, hence the pain sensitivity.
This makes your brain much less sensitive to the pain stimulus coming from the rest of your body.
➦ For Relieving Fever
- The Triggering Factor:
The rise in body temperature is prompted by prostaglandins, particularly PGE2, from the hypothalamus.
Calpol acts as an inhibitor to prevent the formation of these prostaglandins within the hypothalamus.
- The Outcome:
It causes the hypothalamus to regulate your body temperature again to 37 degrees Celsius.
As part of cooling your body down to this new temperature level, the brain directs blood vessels to dilate and sweat formation to occur.

Drug Interactions
1. With other medicines for fever and the common cold:
Most prescription and non-prescription drugs like Combiflam, D Cold Total, Sinarest, Vicks Action 500, and many other cough medicines already include paracetamol.
When taken with Calpol 650 mg, there may be an unintentional overdose of more than 4,000 mg, which results in acute liver failure.
2. In combination with Flucloxacillin:
The administration of Calpol 650 mg alongside an antibiotic flucloxacillin poses a potential danger of developing high anion gap metabolic acidosis (HAGMA).
Patients having severe kidney malfunction, sepsis, or long-standing malnutrition are at much higher risk.
3. Medicines that cause liver toxicity:
Certain medicines cause the liver enzymes responsible for breaking down paracetamol to work faster.
As a result, the liver, thereby damaging the cells in the process, produces increased quantities of the highly toxic chemical compound known as NAPQI.
4. Antiepileptic Medications (Anticonvulsant):
Carbamazepine, Phenytoin, Phenobarbital, Primidone.
5. With blood thinners like Warfarin:
One-off intake of Calpol 650 mg is insignificant. However, long-term, daily consumption of paracetamol will increase the blood-thinning properties of warfarin, thus raising the probability of internal haemorrhage or bruising.
It will be important for you to get your INR monitored by your doctor.
6. Medications that Alter Absorption Speed:
Certain medications can affect the rate at which your stomach empties its contents, leading to changes in the rate at which Calpol begins to work:
7. Metoclopramide or Domperidone:
These medicines help reduce nausea but increase the speed of stomach emptying, thereby increasing the absorption rate of Calpol into the body.
8. Cholestyramine:
This medication is used for lowering blood cholesterol levels or treating some gastrointestinal disorders. It binds to paracetamol in the intestines. Taking it 1 hour before Calpol significantly decreases its absorption.
