When it comes to taking phenylephrine, there are certain medications that should be avoided due to the potential for severe interactions. One such medication is iobenguane I 123, which is used in nuclear medicine imaging. Mixing phenylephrine with iobenguane I 123 can cause a dangerous increase in blood pressure.
Another medication to avoid is isocarboxazid, which is an antidepressant. Combining phenylephrine with isocarboxazid can lead to a potentially life-threatening condition known as serotonin syndrome. Symptoms of serotonin syndrome include rapid heartbeat, high blood pressure, confusion, hallucinations, and seizures.
Linezolid, an antibiotic, is another medication that should not be combined with phenylephrine. Taking these two drugs together can increase the risk of serotonin syndrome as well.
Phenelzine, an antidepressant, is also contraindicated with phenylephrine. Similar to isocarboxazid, combining these two medications can lead to serotonin syndrome. It is important to note that phenelzine should be discontinued for at least 2 weeks before starting any medications that interact with it, including phenylephrine.
Procarbazine, a chemotherapy medication, should not be mixed with phenylephrine. The combination of these drugs can cause a dangerous increase in blood pressure.
Selegiline transdermal, a medication used to treat Parkinson’s disease, should also be avoided with phenylephrine. Taking these two medications together can lead to a hypertensive crisis, characterized by a sudden and severe increase in blood pressure.
Lastly, tranylcypromine, another antidepressant, should not be combined with phenylephrine. Similar to the other antidepressants mentioned, mixing these medications can increase the risk of serotonin syndrome.
It is crucial to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs, herbal supplements, and vitamins, to ensure the safe use of phenylephrine. They can provide guidance on any potential interactions and help you make informed decisions about your medication regimen.
