[Prophylactic use of prostaglandin synthesis inhibitors in connection with IUD insertion].

In a double-blind, randomized, placebo-controlled study conducted at a contraception clinic, 55 women (three nulliparous) were given either ibuprofen 600 mg or placebo 1-4 hours prior to insertion of IUD, 4-6 hours after insertion of IUD and the following morning. Pain was assessed by ten point Numerical Rating Scales during insertion, in the first 4-6 hours and in the following three days. No benefit of ibuprofen was demonstrated at insertion or at any other time during the first three days. The patients were further randomized to type of IUD: TCu-380A and Nova T (R.). No difference in pain scores was evaluated between these.
