Hydrocodone is a narcotic-type medication commonly used in combination with acetaminophen for treatment of mild to moderate pain. Because it's an opiate medication, it may cause physical dependence with long-term use. When medication containing hydrocodone is discontinued, it can cause a number of withdrawal symptoms. Though these symptoms are generally not considered life-threatening, they may be bothersome and debilitating for awhile.
Aches and Pain
Because hydrocodone is used as a pain reliever, its discontinuation may cause increased pain sensation. Some patients experience generalized body aches, especially during the first few days after discontinuation. Others may experience pain in specific areas such as the head or lower back. Lower back pain caused by hydrocodone withdrawal may last for a much longer period. Aches and pain caused by opiate withdrawal may be reduced somewhat by the use of over-the-counter pain medications such as ibuprofen or acetaminophen.
Anxiety
Hydrocodone, like all opiate-type pain medications, produces a sedating or relaxing effect in many patients. Discontinuation of hydrocodone may produce the opposite effect and result in agitation or anxiety. Some patients may experience insomnia as well. These withdrawal symptoms may be reduced somewhat by avoiding high-stimulus activities and environments.
Flu-like Condition
These symptoms may include achiness, fatigue and a general feeling of sickness. Some patients also experience unusual sweating alternating with chills that may produce goose bumps. Over-the-counter medications for pain and fever may help reduce these symptoms.
Intestinal Complaints
Many opiate medications, including hydrocodone, may cause constipation with long-term use. When hydrocodone is discontinued, diarrhea may occur. Other patients may experience loss of appetite or nausea. Excessive diarrhea or vomiting may result in fluid and electrolyte loss, leading to dehydration. Stay hydrated by drinking plenty of water and caffeine-free electrolyte beverages. Severe diarrhea may benefit from the use of an anti-diarrheal medication after consultation with a physician.
Dilated Pupils
Opiates such as hydrocodone may cause constricted pupils in some patients. When the drug is discontinued, one symptom may be dilation. Because exposure to bright or direct light may damage the eyes, take care to avoid direct sun exposure. Wearing sunglasses may also help to protect the eyes if exposure to sunlight or other bright light is necessary.
