The Toxicological Information Center of the Catholic University (CITUC) has released a list of medicines most commonly used in the first half of the year.
Of the nine thousand emergency service and telephone calls, drugs such as clonazepam (8%), paracetamol (6%) and quetiapine (4%) report "top 3".
The first, clonazepam, can cause drowsiness and breathing difficulties in high doses; and if mixed with alcohol, it can be very dangerous.
The other is used as an analgesic, but it is hepatotoxic and the third is an antipsychotic that is used in patients with schizophrenia.
Experts have made sure that human dosing causes a certain degree of toxicity, but not necessarily all exposures cause intoxication.
