also known as Catapress, is often prescribed in adults for high blood pressure. One of the common side effects with it is that it drops the blood pressure. This can result a "head rush", a sense of feeling faint due to too little blood reaching the brain because of low blood pressure.
Clonidine is usually prescribed as a 0.1 mg tablet or as a patch. Small doses (0.05 mg or 1/2of a TTS 1 patch) may be all that is needed to help control overly aggressive ADHD children. There have been some reports of adverse side effects of combining Ritalin and Clonidine.
