Narcan is a medicine that contains Naloxone, a substance that is able to cancel the effects of opioid drugs, such as Morphine, Methadone, Tramadol or Heroin, in the body, especially during episodes of overdose.
Thus, Narcan is often used as an emergency medicine in cases of overdose by opioids, preventing the onset of serious complications, such as respiratory arrest, which can be life-threatening in a few minutes.
Although this medication can completely nullify the drug's effect in cases of overdose and save the person's life, it is very important to go to the hospital to assess all vital signs and start another type of treatment, if necessary. See how treatment is done in case of overdose.
How to use Narcan
Narcan should ideally only be administered by a healthcare professional at the hospital, even in overdose situations. The form of administration that presents the fastest result is to apply the medicine directly in the vein, with effect within 2 minutes.
In some cases, the effect of the drug that caused the overdose may last longer than that of Narcan, which is approximately 2 hours, so it may be necessary to administer several doses during the treatment of an overdose. Thus, the person needs to be hospitalized for at least 2 or 3 days.
In very rare situations, the doctor may prescribe Narcan for personal use, especially if there is a very high risk of someone overdosing. However, the form of administration of the drug must be previously indicated by the doctor, and the dose must be adapted according to the weight and type of drug used. The best way to avoid the complications of an overdose is always to avoid using the drug, so here's how to combat drug use.
