When taken as prescribed, Vicodin is an effective treatment for pain. However, it is also one of the most frequently abused prescribed painkillers and can become dangerous long term. Unfortunately, someone taking Vicodin to treat an injury or chronic pain can slide into an accidental addiction and dependency. When used as prescribed, Vicodin is taken in tablet form. However, some abusers may crush it into a powder for snorting, or combine it with water for injection.
Addiction versus Side Effects
According to The Canyon rehabilitation and substance abuse treatment center, Vicodin will produce side effects the first few times the medication is taken. This happens as the body gets used to the drug. However, addiction symptoms appear after time has passed and the body has built up a tolerance. Side effects can include drowsiness, dizziness, disorganization of thoughts and difficulty paying attention.
Lethargy
According to Michael's House chemical dependency treatment center, families of individuals who are addicted to Vicodin will notice that their loved ones are lethargic and have difficulty staying focused. When questioned, the individual will likely snap and explain that they are just tired; when this occurs repeatedly, including in the middle of conversations, it may be a symptom of Vicodin addiction.
Anxiety and Irritability
When the user begins to run out of medication, he may begin to take just a few in order to fight off the symptoms of withdrawal. According to National Rehabs nationwide drug alcohol and rehab referral, the user's behavior will be quite anxious and they will exhibit irritability until they are able to acquire more medication. An individual's behavior can also become distracted as they become more obsessed about getting the medication required to stave off withdrawal symptoms.
Flu-like Symptoms
According to Casa Palmera treatment center in California, withdrawal from Vicodin can also result in flu-like symptoms, such as joint and muscle aches, night sweats and insomnia. Individuals may suffer from general malaise, runny nose, diarrhea and nausea and vomiting.
