French winter cold medicine habit risks overdose

A common practice in France during winter—using paracetamol-based pain relievers like Doliprane alongside over-the-counter cold medicines—can lead to unintentional overdoses, according to warnings from the National Agency for the Safety of Medicines and Health Products (ANSM).

ANSM sets strict paracetamol limits

The ANSM sets a daily limit of 3 grams of paracetamol from all sources combined, with a maximum of 1 gram per dose spaced at least 4 hours apart. Exceeding these limits, even modestly, can cause cumulative liver toxicity.

Hidden paracetamol in cold medicines

Most cold or flu medicine packets sold without a prescription contain paracetamol, often hidden in small print behind commercial names that suggest winter or cold remedies. This can lead individuals to take a paracetamol tablet for fever and then a cold medicine packet containing additional paracetamol, believing they are using complementary treatments when they are actually combining doses of the same active ingredient.

Combined sources can reach dangerous levels

The ANSM emphasizes that the 3-gram limit applies to all sources of paracetamol, including tablets, cold medicine packets, cough syrups, and other products. For example, taking a 1000 mg Doliprane tablet and a cold medicine packet containing 500 mg or more of paracetamol a few hours apart could dangerously approach or exceed the recommended limit, especially if repeated throughout the day.

Paracetamol's metabolism and risks

Paracetamol is generally considered safe but must be metabolized by the liver before elimination by the kidneys. Repeated exceedance of recommended doses, even modestly, can lead to cumulative liver toxicity, which may not show immediate symptoms. When symptoms do appear, they can be subtle and easily confused with cold symptoms, such as unusual fatigue, nausea, loss of appetite, or discomfort on the right side of the abdomen.

ANSM advises checking medication components

To avoid this risk, the ANSM recommends systematically checking the list of components on medication packaging, not just the commercial name. It also advises consulting a pharmacist before combining multiple treatments for cold or flu symptoms and strictly respecting the 4-hour interval between doses. If unusual symptoms appear after taking several medicines containing paracetamol, a rapid medical consultation is necessary.
