    I'm taking Lipitor 20mg & Niaspan 1000 mg q.d. How serious would it be if I went to q.a.d.?
    billh99 responded:
    I don't know what qad is.

    Did you mean qid - 4 times a day
    or qod - every other day?

    In any case that would be a change in dosage and you need to discuss this with your doctor.

    Sorry. Did mean every other day. Would this effect the efficacy of the meds?

    Note, no medical professional responds in this forum.

    You are reducing the dosing by 1/2. Most likely it will reduce the efficacy, but I have no idea by how much.

    And I don't know why you want to do this.

    If it is for cost Lipitor is now generic and about $15-20/month.

    And you can get plain niacin (not the no-flush stuff) very, very cheaply. But it does have different dosing and can be have worse flushing.

    If it is because of side effects I know that some doctors do prescribe statins every 2 or 3 days.

    I really don't know about the Niaspan, but I suspect that is not practical to change dosing from daily.

    You might ask you pharmacist about this and if you want to change then see your doctor.
