How Safe Are Over-the-Counter Painkillers Like Paracetamol?

Paracetamol is everywhere, you can found it on your shelves, in your bags and in any pharmacy - without a prescription. But the question remains: how safe is this drug, actually?

Paracetamol is the most commonly taken analgesic (painkiller) worldwide and is recommended as first-line therapy in pain conditions by the World Health Organization (WHO). It is widely used as an analgesic (painkiller) and antipyretic (fever-reducing) drug.

How much of this drug is safe to take?

Paracetamol tablets and capsules for adults usually contain 500 mg of paracetamol.

They are available in different forms, including tablets that you swallow with water and those that dissolve in water — often called dissolvable, effervescent, or soluble tablets.

You can take paracetamol with or without food.

For 500 mg tablets or capsules:

• A single dose is 1 or 2 tablets (500–1000 mg)
• Leave at least 4 hours between doses
• Do not take more than 8 tablets (4000 mg) in 24 hours

For 1 g (1000 mg) tablets:

• These are sometimes available by prescription or from a pharmacy
• Take only one tablet per dose
• Do not take more than 4 tablets (4000 mg) in 24 hours

What if you take too much paracetamol?

Taking one extra dose of paracetamol usually isn’t dangerous, but going beyond the recommended limit can harm your liver — so it’s important to seek medical advice if that happens.

If toxicity results from multiple smaller doses taken over time, the first indication of the problem may be abnormal liver function, sometimes with jaundice and/or bleeding.

Other symptoms can affect different parts of the body. The brain may be involved, causing confusion and disorientation (encephalopathy). Kidney function can also decline, leading to reduced urine output or even kidney failure. Blood sugar levels may drop (hypoglycemia), and acid can build up in the blood, resulting in faster breathing. Some people may also experience signs of depression, although this is not always seen.

How can paracetamol overdose be treated?

The medical team will assess you. Based on the information that you give them and the results of your blood tests, they will decide if you need treatment to reduce the chance of damage to your liver. Not everyone will need treatment.

The treatment is a medicine called N-acetylcysteine. It is given as 2 infusions, which take about 12 hours. We give you the medicine through a thin, plastic tube into a vein in your arm. This is called a drip or intravenous (IV) infusion. NAC protects the liver, partly by restoring glutathione levels and partly by helping the liver to combat toxicity.

This treatment might cause mild side effects, such as itching, and feeling or being sick (nausea or vomiting).

Conclusion:

It’s easy to overlook the risks of something so common. But as simple as paracetamol may seem, it carries real consequences when misused. Use it wisely, respect the dosage, and remember — safe use is always in your hands.
