I think it is a very dangerous idea. I do not know about the legal issues in US about telephonic or online consultations, but I do think this website is unethical.
The website does not take any detailed history at all, or even ask questions to confirm the diagnosis. All it asks about the current condition is:
Please list any current medical conditions: Taking an example of acyclovir for herpes infection, I have the following questions about the whole thing:
a) Is the patient supposed to know that he/she has got herpes? Apparently, after reading the Patient Responsibility statement, I got this impression that the patient has to do the whole reasoning from rash to diagnosis of herpes to deciding that acyclovir is suited for herpes of the severity that he/she has got to deciding the dosage and the duration of treatment. He/she is supposed to have read available text about the disease and the drug to be sure that he/she needs it, and won't mind taking it. This is all complete BS. What is over-the-counter if not this?
b) What if the patient does not have herpes, but some other viral rash? A doctor would have diagnosed the presence or absence of herpes at a glance, but which the site is not bothered to check the patient's self-diagnosis.
c) Acyclovir reduces GFR in patients with kidney disease. What if an elderly patient, with so many complaints he can't keep track of, forgets to mention his prostatic hypertrophy. Who will be responsible for any adverse effects? The site cleverly absolves itself, saying it is the patient. Needless to say, the family practitioner looking after this patient would at least remember his BPH, and modify dose or change the medication.
In short, it is like justifying the over-the-counter sale of acyclovir by saying that there is a doctor that will screen patients for any contraindications to the use of medicines that the patients demand, for ailments that the patients have diagnosed, in past/present medical conditions that the patients enumerate. Does not look ethical, does it?
And an odd thing that I noted. Before opening the website, a notice came on my screen, saying that the license of this website was for a duration exceeding the validity of the licensing authority. I donot know what all this means, but it does add to my list of uncomfortable feelings.
