Compared to certain other plants, peace lilies don't need to be pruned very frequently. However, if, for whatever reason, one or more of your lily's limbs or leaves become brown or wilted, you may want to prune the leaves to keep the plant from wasting energy on the dying appendage.
Accutane is a retinoid, and not related to anti-biotics so the side effects are different. However, the list of potential rare side effects of accutane is long and includes headaches, nausea, muscle pain and depression.
Accutane has permanent side effects. I took Accutane at 30 years old for 3 months. I was a healthy, active woman with no pains. I began to have severe back and joint pain, as well as hair loss. Now, eight years later, the pain continues. It took me out of work full-time. It prohibits most of my activities.
