Atarax Drug Interactions
Atarax Drug Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when Atarax is combined with any of the drugs listed above.
You should avoid alcohol while taking Atarax, as undesirable side effects (such as excessive drowsiness, dizziness, or confusion) may result.
Acetylcholinesterase Inhibitor Medications
Taking Atarax 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.
Combining an anticholinergic medication with Atarax (which has anticholinergic properties) can increase your risk of Atarax side effects, such as dry mouth, constipation, dry eyes, or difficulty passing urine. Check with your healthcare provider before taking these medications together.
Other Medications That Cause Drowsiness
Check with your healthcare provider before combining Atarax 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 Atarax, since this medication improves the effectiveness of opioids.
Atarax may increase the risk of a dangerous irregular heart rhythm (arrhythmia) due to a phenothiazine medication if these drugs are taken together. In addition, combining Atarax with a phenothiazine increases the risk of excessive drowsiness.
