In a double-blind randomized controlled trial that evaluated the emergency department treatment of migraine in 66 patients, the combination of IV prochlorperazine (10 mg) and IV diphenhydramine ( mg) was significantly more effective than subcutaneous sumatriptan (6 mg) for the reduction of pain intensity at 80 minutes or time of discharge [ 78 ]. Diphenhydramine was used with prochlorperazine to prevent akathisia and dystonic reactions. However, the possibility of migraine benefit from diphenhydramine cannot be completely discounted. A high drop-out rate upon attempted telephone contact at 72 hours precluded meaningful assessment of headache recurrence, although none of the enrolled patients returned to the emergency department with complaint of headache.

Steroid nasal sprays rarely cause side-effects. This is because they are applied directly to the nose and very little of this medicine is absorbed into the body. Therefore, they are much less likely to cause side-effects in other parts of the body. Occasionally, they cause dryness, crusting, and bleeding of the nose. If this occurs, stop it for a few days and then restart. There have been reports of nasal steroids possibly having an effect on behaviour, particularly in children. This is thought to be rare. However, a few people have reported hyperactivity, problems sleeping, anxiety, depression, and aggression.

The major part of the approximately 150 cm 2 surface in the human nasal cavity is covered by respiratory epithelium, across which systemic drug absorption can be achieved. The olfactory epithelium is situated in the upper posterior part and covers approximately 10 cm 2 of the human nasal cavity. The nerve cells of the olfactory epithelium project into the olfactory bulb of the brain, which provides a direct connection between the brain and the external environment. The transfer of drugs to the brain from the blood circulation is normally hindered by the blood–brain barrier (BBB), which is virtually impermeable to passive diffusion of all but small, lipophilic substances. However, if drug substances can be transferred along the olfactory nerve cells, they can bypass the BBB and enter the brain directly., [12] [13]
