Methods of Administration
Scopolamine can be administered orally, subcutaneously, ophthalmically and intravenously, as well as via a transdermal patch. The transdermal patch (e.g., Transderm Scōp) for prevention of nausea and motion sickness employs scopolamine base, and is effective for up to three days. The oral, ophthalmic, and intravenous forms have shorter half-lives and are usually found in the form scopolamine hydrobromide (for example in Scopace, soluble 0.4 mg tablets or Donnatal).
NASA is currently developing a nasal administration method. With a precise dosage, the NASA spray formulation has been shown to work faster and more reliably than the oral form.

“If men got pregnant, there would be safe, reliable methods of birth control. They’d be inexpensive, too.”
—Anna Quindlen (b. 1952)
“A writer who writes, “I am alone” ... can be considered rather comical. It is comical for a man to recognize his solitude by addressing a reader and by using methods that prevent the individual from being alone. The word alone is just as general as the word bread. To pronounce it is to summon to oneself the presence of everything the word excludes.”
—Maurice Blanchot (b. 1907)
