Can Benadryl, Cetirizine, Pseudoephedrine And Melatonin Be Taken Together?

My friends therapist told them to mix the drugs 2 benedrills, 3 citrizenes, 2 sudo-effedren, 3 melatonins, and two aderols. She is allergic to sudo-effedren. What would happen if she did do this. The therapist said it would help her sleep and not to tell anyone she recommended that.So I was a little suspicious.

Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

It may cause harmful interactions. Both Adderall and Pseudoephedrine can increase your blood pressure and heart rate, and combining them may enhance these effects. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Taking Cetrizine together with Benadryl may increase side effects such as excessive drowsiness, difficulty concentrating, impaired thinking, and motor in coordination which may result in falls and injuries.You should avoid activities requiring mental alertness such as driving or operating hazardous machinery while taking these medications.

Hope I have answered your query. Let me know if I can assist you further.
