My medication I received a few weeks back to deal with my IBS pain (amitriptyline) is also an antidepressant. I knew this beforehand and didn't mind it. It's been working wonders for my neuropathic pain (from the IBS) AND it's making me less anxious, and it's almost entirely removed my headaches.
However, this weekened I noticed that my pulse was really high. I always have a high resting pulse at around 80-something, but it's been way over normal now, between 90 and 100. When it first happened I had my fourth ever panic attack which sucked (luckily I wasn't alone so it went over easily).
Apparently this is a very common side effect (more than 1 in 10) and might just be my body adjusting to the medication, as they said it usually takes a month for the medication to completely start working (I've been on it for about three weeks), but I'm going to book an appointment with a GP tomorrow just to be sure (I didn't have time today), because it was really scary. I'm on a small dose of 25mg once a night before I go to bed, and apparently there's even 10mg doses if I need to take a lower amount.
Thankfully I've not had any chest pain nor have I had any other scary heart-related symptoms, which leads me to believe it's the medication. Still sucks though because I really want to keep taking it as it's improving my quality of life so much, as I've walking around with untreated IBS pain for 13 years.
