Patients must tell their doctor immediately if they suspect an overdose with larger amounts of Nitrolingual Spray.
Depending on the extent of overdose, side effects may occur in exaggerated form, e.g. sharp drop in blood pressure (hypotension), with a reflex increase in pulse rate, feeling weak, light-headed and drowsy, as well as headache, skin redness, nausea, vomiting and diarrhoea.
