There's no way to know if it is actually good or not. It should not have been left out at room temperature for that long. You will have to make the decision whether or not to use it.
Yes. If it's only been out three hours and it's still in the packaging, it's fine. Take some and put it back in the fridge as soon as you can, but probably even longer than that would be okay. If it's out of the packaging, it would still be safe, but probably dry out and perhaps unappealing.
If acetylcysteine has been left out at room temperature for 3 hours, it may still be safe to use, but this can depend on the specific product and its storage instructions.

I've had a couple of huge pots of Gumbo spoil on me because (1st time) I left it out over night (2nd time) I though I refrigerated it too fast, while it was still hot.You tell it's spoil when the soup is all bubbly with a foam like film and has a tainted smell/taste.Here's what I found out at ehow:Store your gumbo immediately after you're done cooking. For short-term storage, the gumbo can go in an airtight plastic container in the refrigerator. Seafood gumbo will last at most three or four days in the refrigerator. Keep the container at the bottom of the refrigerator, where it's coolest.2 Check the thermometer in the refrigerator, and ensure that the temperature is 40 degrees Fahrenheit or below. The freezer should be at least 0 degrees Fahrenheit.3 Freeze your gumbo to store it for longer periods. Put it in a sealable freezer bag, squeeze out the air and seal the bag before placing in the freezer. If you don't need to defrost it all at once, freeze smaller portions in several bags.4 Defrost your gumbo before eating it by transferring it from the freezer to the refrigerator, or letting it sit in a sealed bag in a bowl of cold water. Change the water every half an hour. Reheat your gumbo and eat it immediately after it finishes defrosting.Read more: How to Prevent Gumbo From Spoiling | eHow.com http://www.ehow.com/how_7295611_prevent-gumbo-spoiling.html#ixzz1c9YGHtpD
