Some treatments are more direct than others. In the case of IV Therapy, this treatment is used in order to achieve faster absorption of medication for the patient which cannot be accomplished through orally taken medication. It involves directly injecting fluids through the veins.
Aside from delivering medication through the blood stream, IV Therapy can also be used for fluid replacement to avoid dehydration.
IV Therapy has to be administered by a skilled nurse under the direction of a physician.
