| ==Overdosage==
| |
| | |
| | |
| ===Symptons===
| |
| Inhaled doses of 5 to 10 drops of amyl nitrite may cause violent flushing of the face, accompanied by a feeling of imminent bursting of the head and very excessive heart action. The inhalation of larger amounts may produce a feeling of suffocation and muscular weakness. Symptons comparable to shock may be produced such as weakness, restlessness, sweating, [[pallor]], [[nausea]], [[vomiting]], [[syncope]] and [[incontinence]] attributable to pooling of blood in the postarteriolar vessels and failure of the venous blood to return to the heart.

| | |
| ===Treatment===
| |
| Measures which facilitate venous return such as head low posture, deep breathing and movement of extremities may be used. The use of [[epinephrine]] aggravates the shock like reaction. [[Methylene blue]] should be injected for treatment of severe [[methemoglobinemia]] with [[dyspnea]]. For treating [[cyanide poisoning]], [[methylene blue]] is contraindicated where nitrites cause iatrogenic [[methemoglobinemia]].<ref name="dailymed.nlm.nih.gov">{{Cite web | last = | first = | title = AMYL NITRITE INHALANT [JAMES ALEXANDER CORPORATION] | url = http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=c1b6e536-df5f-4f76-8e3c-6dc2f1e9975e | publisher = | date = | accessdate = 30 January 2014 }}</ref>
