Drug Interactions With Fesoterodine

Fesoterodine Drug Interactions Explained

The following sections explain in detail the potentially negative interactions that can occur when fesoterodine is combined with any of the drugs listed above.
 
Acetylcholinesterase Inhibitors
Taking fesoterodine 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 fesoterodine (which is also an anticholinergic medication) can increase your risk of fesoterodine side effects, such as dry mouth, constipation, dry eyes, or difficulty passing urine.
 
Certain Antifungals or Antibiotics
Some antibiotic or antifungal medications may increase the level of fesoterodine in your blood. Your healthcare provider may recommend that you take a lower fesoterodine dosage if you are taking certain antibiotics or antifungals.
 
Nefazodone (Serzone)
Nefazodone can increase the level of fesoterodine in your blood. Your healthcare provider may recommend that you take a lower dose of fesoterodine if you are taking nefazodone.
 
Pramlintide
Both pramlintide and anticholinergic medications (including fesoterodine) 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.
 
Protease Inhibitors
Protease inhibitors may increase the level of fesoterodine in your blood. Your healthcare provider may recommend that you take a lower fesoterodine dosage if you are taking a protease inhibitor.
