Drug Interactions With Trihexyphenidyl

Trihexyphenidyl Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when trihexyphenidyl is combined with any of the drugs listed above.
 
Acetylcholinesterase Inhibitor Medications
Taking trihexyphenidyl 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.
 
Anticholinergic Drugs
Combining an anticholinergic medication with trihexyphenidyl (which is also an anticholinergic medication) can increase your risk of trihexyphenidyl side effects, such as dry mouth, constipation, dry eyes, or difficulty passing urine.
 
Pramlintide
Both pramlintide and anticholinergic medications (including trihexyphenidyl) can slow down the movement of food through the digestive tract. Taking them together can increase the risk of constipation or nausea. Talk with your healthcare provider before combining these medications.
