The lethal dose of morphine in Servedol varies depending on the patient's tolerance to opioid drugs, age, weight, health condition, and how the drug is administered - whether orally or intravenously. As for the oral dose, a dose of 120-200 mg can be fatal for a person who has not developed a tolerance to morphine. In the case of an intravenous dose, it is 30-60 mg.

If a patient takes opioids regularly, their tolerance to morphine may be much higher, meaning they can take higher doses without the risk of serious life-threatening, respiratory depression, coma, or death. If a morphine overdose is suspected, prompt medical attention is necessary.

Apo-Zolpin does not contain morphine, but the active ingredient zolpidem. Great caution should be exercised when using both drugs. If you know a person who wants to increase the dose of the medication on their own and thus it may end badly for them, call the emergency number (112 in Poland) or take them to the nearest hospital.
