What is with the preferences
and then your question?
That is weird…
You’re lucky I actually bothered to continue to scroll down and actually read your question because I very nearly just left the page thinking it was a mistake.
Anyway… if you were put on amytriptiline for the headaches could it have been because the headaches were actually migraines? Migraines can cause nausea as well as headache and amytriptiline is very commonly prescribed to prevent them.
The concern about using citalopram and amytriptiline together is that very rarely using two drugs of this same group at the same time (SSRI’s) can cause a reaction called Serotonin Syndrome which is where because both the drugs are working in the same way they can cause you to get too much serotonin in your brain giving rise to a various symptoms. I only know about this because I was in hospital last week really sick with a query diagnosis of severe migraine, query MS flare or possibly Serotonin Syndrome. As it turned out in my case it was a MS flare brought on by a particularly bad UTI and a migraine from hell.
Headache and nausea alone are not symptoms of Serotonin Syndrome. Symptoms may include things such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhea.
But as always with any concerns particularly where medications are involved, don’t take our word for it! Do check with your Dr if you have any concerns.
Also do be aware that amytriptiline does take up to a couple of weeks to build up to full therapeutic levels so you may still get migraines for a bit after starting it. (You don’t say how long exactly you have been on it)
Hope this helps and you feel better soon.
PS Please put me out of my misery and explain the preferences, the Union Jack and English stuff… Most odd and confusing
