Neocitran

I pulled this up on google for interactions with phenylephrine hcl.

This drug should not be used with the following medications because very serious interactions may occur: MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine).

Avoid taking MAO inhibitors within 2 weeks before, during, and after treatment with phenylephrine. In some cases a serious, possibly fatal drug interaction may occur.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: blood pressure medications (especially reserpine, guanethidine, methyldopa, beta blockers such as atenolol, or calcium channel blockers such as nifedipine), other decongestants (taken by mouth or applied in the nose), digoxin, tricyclic antidepressants (e.g., amitriptyline, imipramine).

This medication may worsen the serious side effects of some medications used for migraine headaches (e.g., sumatriptan, naratriptan, zolmitriptan, ergotamine). Consult your pharmacist or doctor for more details.
