Interactions between your drugs

Major

HYDROcodone QUEtiapine

Applies to: Vanex Expectorant (guaifenesin / hydrocodone / pseudoephedrine), quetiapine

Using narcotic pain or cough medications together with other medications that also cause central nervous system depression such as QUEtiapine can lead to serious side effects including respiratory distress, coma, and even death. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Do not drink alcohol or self-medicate with these medications without your doctor's approval, and do not exceed the doses or frequency and duration of use prescribed by your doctor. Also, because these medications may cause dizziness, drowsiness, difficulty concentrating, and impairment in judgment, reaction speed and motor coordination, you should avoid driving or operating hazardous machinery until you know how they affect you.

Using narcotic pain or cough medications together with QUEtiapine may also increase the risk of constipation. Severe complications may include intestinal obstruction, fecal impaction, or other serious and even life-threatening injuries to the bowel that may require hospitalization or surgery. You should maintain adequate hydration, physical activity, and fiber intake during treatment with these medications to help prevent constipation. Talk to your healthcare provider to see if taking a laxative prophylactically may be appropriate for you. Seek immediate medical attention if you experience signs and symptoms of constipation such as difficulty passing stool, incomplete passage of stool, hard or dry stool, and decreased bowel movement frequency (especially if less than three times a week), or if you have symptoms that could indicate more serious gastrointestinal problems such as nausea, vomiting, bloating, and abdominal pain or swelling. Prompt treatment with appropriate laxatives and other measures are essential to minimize the risk of complications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Major

HYDROcodone food

Applies to: Vanex Expectorant (guaifenesin / hydrocodone / pseudoephedrine)

Do not use alcohol or medications that contain alcohol while you are receiving treatment with HYDROcodone. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. If you are taking certain long-acting formulations of hydrocodone, consumption of alcohol may also cause rapid release of the drug, resulting in high blood levels that may be potentially lethal. Likewise, you should avoid consuming grapefruit and grapefruit juice, as this may increase the blood levels and effects of hydrocodone. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of HYDROcodone, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

Moderate

pseudoephedrine food

Applies to: Vanex Expectorant (guaifenesin / hydrocodone / pseudoephedrine)

Both pseudoephedrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
