Patients inhaling nitric oxide may feel light headed, faint or dizzy when they suddenly rise from a lying or sitting position, as stated by Drugs.com. A patient who is experiencing side effects should notify a nurse or doctor at once as they may require medical attention.

Nitric oxide may cause hypotension, blood in the urine, hyperglycemia and hematological effects such as methemoglobinemia, according to Drugs.com.
