Risk of Misuse and Addiction. Misusing Conzip can lead to serious side effects like coma or death. Misuse means taking a medicine in a way other than how it was prescribed. Take Conzip exactly as prescribed. Tell your healthcare provider if you feel that Conzip is not working. Call your healthcare provider right away or go to the nearest emergency room if you have any of the following serious symptoms.

Breathing Problems. Conzip may cause slow or shallow breathing, especially if you have breathing problems from another condition or take other medicines that can slow your breathing.

Get emergency help right away if you have any of the following symptoms.

- Feeling dizzy, lightheaded, or fainting
- Changes in your heart rate or rhythm, such as a fast, slow, pounding or skipping heartbeat

Increased Pain Sensitivity (Hyperalgesia). Conzip can cause an increased sensitivity to pain. It can cause things that normally cause pain to feel more painful than usual. Conzip can also cause allodynia. This happens when things that normally do not cause pain, such as wearing glasses or brushing your hair, become painful. If your pain increases, do not take extra doses of Conzip. This could cause you to overdose or develop other serious side effects. Call your healthcare provider right away if your pain increases, you feel more sensitive to pain, or if you develop pain in other areas of the body.
Serotonin Syndrome. Serotonin syndrome is when there is too much of a substance called serotonin in your body. Conzip can cause serotonin syndrome when it is taken alone or with other medicines that affect serotonin. This condition can be life-threatening. Get emergency help if you have any of the following symptoms of serotonin syndrome.

- New or increased thoughts of suicide or death
- Suicide attempt
- New or increased feelings of anxiety, depression, or other unusual changes in mood or behavior
Reduced Adrenal Function. Long-term use of Conzip can cause your body’s adrenal glands to stop making as much cortisol (the stress hormone). This is known as adrenal insufficiency. Adrenal insufficiency can get worse if your body is under stress because of fever, surgery, or trauma. Tell your healthcare provider if you have any of the following symptoms of adrenal insufficiency.
- Nausea and vomiting

- Feeling weak or tired
Sphincter of Oddi Spasm. The sphincter of Oddi is a muscular valve in your body that controls the flow of bile and digestive juices from the pancreas into the small intestine. When this valve spasms, it may feel like getting a tight muscle cramp, causing pain and blocking the flow of these juices, which can lead to discomfort and digestive problems. This is more likely to happen if you do not have a gallbladder. Get emergency medical help if you have new or worse stomach pain or pain in the upper right side of your stomach-area that travels to your back or shoulder, with or without nausea and vomiting.
