No. Your prescribed Amitriptyline dosage should significantly decrease acidity and gastric (stomach) ulceration. Stomach ulcers produce an intense burning sensation in the stomach. The emptier the stomach, the higher the intensity of pains. Although, if at any time you encounter abdominal distress, stomach pains, or feel tenderness in your pelvic area, let your doctor know immediately.

2. How long does Amitriptyline take to work for migraines?

Amitriptyline for nerve pain can turn out to be a slow solution but has immense long-term benefits. Some patients feel relief within one to two weeks, and some after six to eight weeks. It all depends on how your body reacts and absorbs the drug. Nevertheless, try not to overdose or compensate for any missed doses. Both come with some harsh experiences and side effects.
