Causes and Treatment of Paresthesia

6. Causes: Medication

Some medications can cause paresthesia, including certain anticonvulsants and chemotherapy medications. Strong intravenous drugs such as opioids and narcotics can also cause the sensation, especially when used in non-medically. Withdrawal can also cause paresthesia; in particular, people withdrawing from benzodiazepines, a class of drugs used to treat anxiety, panic disorder, and insomnia, often experience tingling sensations. People exposed to certain poisons, including mercury, radiation, and some insecticides may also have paresthesia.
