ED drug dosing

How does a prescriber determine which strength of an ED medication to dispense? My coworkers and I have come up with all sorts of serious and comical ways, but I am seriously asking if anyone actually knows.

I guess it depends on the hardness...er...difficulty

I would guess its dose would be limited if there was a concern about another concurrent disease state that could cause hypotension or some other adverse effect. Other than that, beats me.

I guess degree of ED, experience with other ED drugs, and other health conditions/cause of ED?

Since everybody's guessing... I'd guess that you start out with the lowest dose and then increase the dose until the patient achieves satisfactory results.

ETA: My guess was incorrect... most patients start out with Levitra 10mg ( if >65 yo - 5mg), Viagra 50mg or Cialis 10mg and then dose is adjusted from there depending on results.

Most of the ones I've seen will write for the highest strength available and have people split the tab if they can get by with a lower dose. Lower dose tabs seem to be reserved for the non-pill splitting population who is willing to pay roughly the same price per tab for a lower dose tab.

I'm not trying to hijack this thread, but can ED drugs lower your blood pressure? I mean, they should if they are vasodilators. But if that's the case, can they be used for hypertensive patients? Why or why not?

This question probably shows how little I know of drugs...😳

I think I read on a packet insert that it doesn't typically cause a blood pressure drop unless taken concurrently with other blood pressure medications. But I don't quite understand that because if its a vasodilater it should but who knows? It is also puzzling that drugs like Cialis are only good once in the 36-hour period although the drug is still in circulation. Weird because the drug should still be effective but you only get one shot.

Side note: the other day an insurance sent back a notice that "oral sex medication" not covered. After laughing like a 4th grader in sex ed for twenty minutes the pharmacist had to explain to me that it referred to sex medications to be taken orally.

I do not like your pharmacist's definition.

They make a low dose Viagra called Revatio.
