Which of the following is a common side effect of Clonidine?

Clonidine is an alpha-2 adrenergic agonist primarily used to manage hypertension and can also be effective in treating attention deficit hyperactivity disorder (ADHD) and opioid withdrawal symptoms. One of the common side effects associated with clonidine is nausea. This occurs due to its action on the central nervous system, which can affect various physiological functions, including gastrointestinal motility and the vomiting center in the brain.

While headache, rash, and insomnia can occur in some individuals taking clonidine, they are not as commonly reported or as significant in terms of prevalence compared to nausea. This clarity on the side effect profile is vital for healthcare providers in order to monitor and manage potential adverse reactions effectively when prescribing clonidine.
