Vistaril Drug Interactions

Vistaril Drug Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when Vistaril is combined with any of the drugs listed above.
 
Alcohol
You should avoid alcohol while taking Vistaril, as undesirable side effects (such as excessive drowsiness, dizziness, or confusion) may result.
 
Acetylcholinesterase Inhibitor Medications
Taking Vistaril with an acetylcholinesterase inhibitor can make both medications less effective. Your healthcare provider may need to monitor you more closely and adjust your dose of these medications to prevent interactions from occurring. Check with your healthcare provider before combining these medications.
 
Anticholinergic Drugs
Combining an anticholinergic medication with Vistaril (which has anticholinergic properties) can increase your risk of Vistaril side effects, such as dry mouth, constipation, dry eyes, or difficulty passing urine. Check with your healthcare provider before combining these medications.
 
Other Medications That Cause Drowsiness
Check with your healthcare provider before combining Vistaril with any other medication that also causes drowsiness, as undesirable side effects (such as excessive drowsiness, dizziness, or confusion) may result. Also, the dosage of opioids (such as morphine) can usually be reduced significantly, often by as much as 50 percent, when combined with Vistaril (as Vistaril improves the effectiveness of opioids).
 
Phenothiazines
It is possible that Vistaril may increase the risk of a dangerous irregular heart rhythm (arrhythmia) due to a phenothiazine medication. Additionally, combining Vistaril with a phenothiazine increases the risk of excessive drowsiness.
