The prolonged use of opioids changes how the brain functions, thus causing physical dependence and requiring a steady supply of opioids. If an individual becomes physically sick after cessation of opioid use, it can be a sign that dependency has developed. Opioid withdrawal is a set of symptoms that arises from the sudden reduction of opioid consumption.
There are multiple signs of opioid withdrawal; they are as follows:
• Anxiety
• Restlessness
• Insomnia
• Yawning
• Cold
• Watery eyes
• Dilated pupils
• Body aches
• Sweating
• Vomiting
• Belly cramps
• Diarrhea
• Fever
• Fast heartbeat
• Rapid breathing
• High blood pressure
• Hallucinations
• Seizures
If you see the above symptoms in a loved one, they may be experiencing opioid withdrawal. Symptoms typically begin within the first 24 hours of opioid cessation and usually start to improve within 72 hours.
Different drugs remain in your system for different amounts of time; this can affect the onset of withdrawal symptoms.
