On this page, you can find all of our Add-Ons. Most of the products below can be administered intravenously (IV) or as an intramuscular (IM) injection. However, some can only be administered by a single route. The products that can only be administered via a single route will state the route in the name. Our IM injections are administered to the ventrogluteal or deltoid muscle. Our IV add-ons are administered concurrently with an IV hydration therapy.

Comparing the two routes of administration, therapies administered via an injection are absorbed more slowly than an IV and therefore stay in your system longer. Conversely, those administered through an IV are more rapidly absorbed and the benefits are more immediate.
