About a week ago, one of my doctors put me on 10 mg of Elavil at bedtime to help with pain and sleep. After several days, when it was doing neither, I called and was advised that I should up the dosage to 20 mg. I tried that last night and woke up with a horrible headache. I used to awaken with headaches a lot because of TMJ problems, but that hasn't been happening recently, and I wear an NTI device over my front teeth to keep my teeth from grinding in my sleep. Buffered aspirin was able to take care of the headach (at least temporarily), but I also noticed I was stiffer and more achy today. I did have PT on my shoulder yesterday, but it was mostly ultrasound treatment that certainly felt good as I was receiving it. I called my doctor and left two messages today about my experience with Elavil at the higher dose, but although his nurse called back, she said she needed to check with him about whether I should continue at 20 mg, drop back to 10 mg or drop the Elavil completely. As of this writing (just past 6:30 p.m.), I haven't heard back from the doctor. I know a lot of people on this board have tried Elavil (amitriptilene) with varying results, but I don't recall whether anybody mentioned headache as a side effect. Headache *is listed* as a side effect on the information sheet the pharmacist gave me with the prescription. I realize that everybody is different, but I'd appreciate it if you would share your Elavil experience with me. Thanks. --Laura R.M.
