Diphenhydramine, an antihistamine, can cause hypotension primarily due to its anticholinergic effects and central nervous system depression. It blocks histamine H1 receptors, which can lead to vasodilation and decreased vascular resistance. Additionally, its sedative properties may impair the body's ability to regulate blood pressure, particularly in older adults or those with pre-existing conditions. These combined effects can result in lower blood pressure.
not sure
Hypertension can cause vomiting, diarrhea and fever.
Not a good idea,ambien for sleeping,but diphenhydramine can cause sleepiness too.
by di receptor stimulation
This low level can be a cause of hypotension.
Possibly, yes, especially in large dosage.
Diphenhydramine (Benadryl) is a Type I sedating antihistamine and should have auxiliary label "May Cause Drowsiness".
The prognosis for a patient with orthostatic hypotension depends on the underlying cause. In some cases, treating the underlying condition can improve or resolve the symptoms. However, in more severe cases or if left untreated, orthostatic hypotension can lead to complications such as falls and fainting episodes. Regular monitoring and management are important for improving outcomes.
Medications that can cause orthostatic hypotension include Tricyclic antidepressants, antipsychotics, monoamine oxidase inhibitors, antihypertensives, diuretics, vasodilators, Levodopa, beta-blockers (heart medications), and blood pressure medications
In the context of hypotension, orthostatic hypotension is the same as postural hypotension.
it will cause hypotension, dizziness when standing up, dry cough. So no not really
