Reference for Cymbalta

I have copy/pasted a first page passage from the above - with bolded inclusion:

What are the possible side effects of duloxetine (Cymbalta)?

Get emergency medical help if you have any of these signs of an allergic reaction: skin rash or hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Report any new or worsening symptoms to your doctor, such as: mood or behavior changes, anxiety, panic attacks, trouble sleeping, or if you feel impulsive, irritable, agitated, hostile, aggressive, restless, hyperactive (mentally or physically), more depressed, or have thoughts about suicide or hurting yourself.

Also another part of calling your doctor:

Call your doctor at once if you have any of these serious side effects:

nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
feeling like you might pass out;
agitation, hallucinations, fever, fast heart rate, overactive reflexes;
very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors;
easy bruising, unusual bleeding;
painful or difficult urination;
headache, trouble concentrating, memory problems, weakness, feeling unsteady, loss of coordination, fainting, seizure, shallow breathing or breathing that stops; or
severe skin reaction -- fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain, followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.

This drug is good when it works, but also carries some horrendous side effects when suddenly stopped, and I am not familiar with what time period of use is involved for NOT (meaning, was your limited use not a risk ) suddenly stopping it.

Please, I hope you have contacted , or will be contacting your Doctor soon.
