Can you give gravol to a normally altered (Alzheimer’s) patient?

Hi Doc(s), Two unrelated questions I've been pondering over the last couple of days: 1. In the field I've noticed some paramedics withhold dimenhydrinate administration if the patient has already taken any Gravol in the last 4-6 hours. However, the medical directive does not specify a time and simply states overdose on antihistamines or anticholinergics or tricyclic antidepressants. My understanding of their logic is that additional Gravol may cause an overdose in the patient however Gravol brand themselves recommend a dose of 1-2 50mg capsules every 4hrs PRN... Could you please provide some further clarification on this practice, and if we should still be administering it if we do not suspect an overdose but that the medication has been taken appropriately. (and similar practice for if the patient is taking tricyclics or anticholinergics as prescribed to them) 2. I recently had a COPD exacerbation patient who I believe would have benefitted greatly from CPAP. He had equal lung sounds through all fields with no paroxysmal chest movement, however there was a recent history of a collapsed lung approx. 6 weeks prior. (Unknown cause, from his history I suspect possibly a bleb/bullae) The current extenuating circumstance of COVID-19 aside, should CPAP be considered in this patient? Although I am not suspecting a current pneumothorax, due to the recent history I would think that weakening of the lung tissues could put the patient at greater risk for a recurrent event if subjected to significant positive pressures. Thank you and stay safe!

I am an PCP IV certified paramedic, working with a non IV medic. If we have a hypoglycemic patient do I need to attend & consider D10/D50 or can my non IV partner treat the patient with Glucagon instead?” Same question for Gravol; do they need to get it IV or can non IV certified medic give it IM?

How should I proceed if the patient I’m treating tells me that they have already self-administered Gravol, within the past hour, but has since vomited multiple times. Do I proceed with IV Gravol as she has likely thrown up her self-administered dose?

When considering Gravol, if the pt has taken any antihistamines, anticholinergics, or tricyclic anti depressants should we withhold Gravol or only if they already appear to have overdosed? For example, would it be o.k. to give the patient Gravol if they take a daily antihistamine for allergies?

Question: In reference to LOA and gravol administration: a patient who has had a fall and struck their head, has a GCS of 14 (4,4,6) and is alert to person but not place and time, confused about previous events, but can follow commands and is answering some questions appropriately (ie... Birthday, wifes name). Does this rule them out for gravol? My concern is if they are nauseated and we dont treat it early, vomiting and being supine on a spinal board can be very difficult to manage by yourself. I appreciate the definition of LOA is a GCS less than normal for the patient. Can you explain the reasoning for this condition?

Question: I had a scenario where my patient stated he had a few drinks and was slightly drowsy, he answered all my questions fine and was alert to person place and time, once in the ambulance he became nauseous and began vomiting two emesis bags full, I gave gravol in this situation after listing off the contraindications and patient confirming there were none. My question is, would this have been acceptable?

Question: In regards to gravol. Pregnancy is not a contradiction but after doing research most medical journals state the following: because the studies in humans cannot rule out the possibility of harm, Dimenhydrinate should be used during pregnancy only if clearly needed. What are your thoughts?

Question: According to the PCP Dimenhydrinate Learner's Certification Package on the SWORBHP website under training materials, it says "It is also very important to note that Dimenhydrinate should not be administered to anyone with a recent history of closed head injury or medical history of a seizure disorder" (due to the decrease of seizure threshold)

However, history of seizure disorders is not a contraindication in our medical directives. Does this mean we are able to treat patients presenting under the nausea and vomiting protocol with a history of seizure disorders with Dimenhydrinate?
