The following sections explain in detail the potentially negative interactions that can occur when protriptyline is combined with any of the drugs listed above.
Protriptyline may enhance the effects of alcohol. This can lead to an increased risk of suicidal thoughts and other overdose symptoms. Make sure to talk with your healthcare provider about drinking alcohol while taking the drug.
Taking protriptyline with anticholinergic medications may cause increased side effects. Talk to your healthcare provider before using these medications together, as your dosages may need to be reduced. Since anticholinergic medications are found in some over-the-counter medicines, do not treat yourself for the common cold, a cough, or allergies without first talking to your healthcare provider.

Also, certain arrhythmia medications can increase the level of protriptyline in your blood, increasing your risk of side effects. Talk to your healthcare provider before taking these medications together.

Taking cisapride with protriptyline can increase your risk of a dangerous irregular heart rhythm called QT prolongation. Do not take these two medications together.
