Fentanyl is a synthetic opioid drug that can be extremely potent and dangerous when used illicitly. It is important to note that fentanyl can be safe and effective when used as prescribed by a doctor for pain management. However, when used illicitly or in high doses, fentanyl can cause a range of serious health problems, including overdose and death. Some signs of a fentanyl overdose may include slowed or shallow breathing, extreme drowsiness, confusion, or difficulty speaking blue or gray lips and nails, pinpoint pupils, and unconsciousness. If you suspect someone is experiencing a fentanyl overdose, it is important to seek emergency medical attention immediately. Naloxone is a medication that can help reverse the effects of an opioid overdose, including fentanyl. It is important for people who use opioids, including fentanyl, to carry naloxone with them and know how to use it. Naloxone can be obtained without a prescription in many U.S. states and is available in several different forms, including nasal spray and injection. It is also important for people who use fentanyl, or any other substance, to seek help and support if they are struggling with addiction or other related health problems. Treatment options may include medication-assisted treatment, counseling, and support groups.
