Ovidrel is eliminated from the body with a mean terminal half-life of approximately 29 ± 6 hours following subcutaneous administration and around 26.5 ± 2.5 hours following intravenous administration, reports Drugs.com. This means every 29 or 26.5 hours Ovidrel loses half of its pharmacological activity.
According to Drugs.com the amount of Ovidrel a person is exposed to is not directly proportional to the pharmacological effect it has. It appears that the maximum effect is reached at a dose of 250 micrograms. When given a subcutaneous administration at a dose of 250 micrograms, the serum concentration peaks at approximately between 12 and 24 hours. Of the dose, one-tenth is excreted through the urine.
