In response to the above comments about Victoza making one weak in the legs, and causing dizziness - those are signs are (ultra/very) low blood sugar. They are stated within the patient information packet that accompanies Victoza’s Prescribing Handout under the Side Effect Section that says if you experience any of the following, contact your doctor (immediately). Basically, if you are feeling jittery, sweaty, dizzy, having weakness in certain muscle regions or experiencing loss of control of major muscle groups, (or in some cases, even feeling confused and/or disoriented), then in 99% percent of cases this is not a normal reaction to a normal dose of Victoza but rather a (specific or series of specific) side-effect(s) that need to be reported to your doctor at once. The aforementioned side-effects, according to my pharmacist, and according to the Prescribing Information, very strongly indicate that one’s dose of Victoza is simply disproportionate to one’s needs, i.e. that one’s dosage is simply too high for one’s body and needs to be lowered. Your doctor or prescriber should be able to make that determination without the need for completely discarding the medicine altogether, before starting you on a brand new replacement medicine. My recommendation: if you are feeling side-effects that correspond with too low of blood sugar, try decreasing your Victoza dose first before abandoning it outright, and if you are not feeling/noticing enough of a decrease in your blood sugar or A1C, try increasing your Victoza dose (unless you are already at the max of 1.8mg - in which case, try the same medicine at a higher dose, called Saxenda), before adding more or a new medicine(s) of a whole new, different type with their own set of issues/side-effects. I know of multiple instances where Victoza doses have had to be either raised or lowered in order to reach a therapeutic level. And in most cases, that was sufficient to correct the problem.
Additionally, in the specific case of Victoza, if at the max dosage of 1.8mg a client is not receiving what is yet deemed to be a therapeutic effect, there is also a unique alternative called Saxenda, which is literally the/an identical medication but was branded for weight-loss instead so it has a higher maximum range of dosing which may be helpful for some individuals.
Note: Not all insurance companies will cover Saxenda as a A1C/Diabetes medication (even though it has the same active ingredient as Victoza, just at a higher dose), in the same manner that not all insurance companies will cover Victoza for weight-loss, such as my own insurance (even though it has the same ingredient as Saxenda - a FDA approved weight-loss drug). Ironic, I know.
