Some patients ask, “Why does it have to be IV? I don’t like needles!”
IV is the best route for your brain to receive ketamine because of something called bioavailability. In addition, it is also more effective, more precise, and safer for you.
Receiving a medication intravenously is the only way to have 100% bioavailability. Let’s take a look at the different bioavailability percentages based on what route you receive ketamine:
Intravenous: 100%
Intranasal: 25-50%
Sublingual (under the tongue): 30%
Orally (by mouth): 16-24%
When we give ketamine intravenously, we know exactly where your entire dose is going: straight to your brain. The same cannot be said for other forms of ketamine.
IV ketamine is by far the safest and most effective approach in using ketamine to treat depression. You are in a comfortable setting with healthcare providers with you the whole time, the potential for side effects is low, and you are certain that the dose you receive is the dose that is going to your brain, maximizing the benefits of this cutting-edge treatment.
