Brief Answer:
Medications such as phenergan can affect patients with Alzheimers

Detailed Answer:
Good evening. Thank you for your question. You didn't explain why he was given phenergan on the air ambulance unless they simply do it as routine to prevent people from getting AIRSICK?

However, phenergan's pharmacological action will clearly sedate your husband and more so because of his Alzheimer's condition. The typical duration of action of the drug is likely going to be at least 1.5-2.5x longer because of his already less than optimal cognitive condition.

In the future since you've seen how he responds to the phenergan I would suggest that you make sure he doesn't get this medication unless he is actually suffering from severe nausea and vomiting or is complaining of some kind of motion, air, or sea sickness. This type of response is common in both elderly patients as well as those with conditions such as DEMENTIA of ANY TYPE.

I suggest you keep a very close eye on him and not let him get up on his own since he may just fall and hurt himself. The condition of being exacerbated in his state of mental functioning will get better once the medicine wears off and his brain is "released" from its effects which could take up to double the length of time of the drug's half life. Another I'll mention about Phenergan that I'm not happy about is the fact that it can cause sudden twitches in the face, limbs, and spasms in the face, neck, and torso. Others may call them TICS.....Phenergan can and does cause this type of side effect which will take up to 3-4 weeks to completely clear so do be patients with him.
