Dalfylline is also known as treprostinil acetate, which belongs to the gonadotropin-releasing hormone class of drugs. The main purpose of pre-investigation injections of treprostinil acetate is so that multiple mature and high quality eggs can be obtained at the time of egg retrieval. Triptorelin acetate is mainly used for the treatment of endometriosis, uterine fibroids, precocious puberty, and prostate. This is because Triptorelin Acetate inhibits the secretion of gonadotropins. This treatment ensures suppression of LH spikes, which improves the quality of follicle production and increases the number of follicles. This is why most women need to work with their doctor to get Triptorelin Acetate injections prior to IVF. This is a prescription drug and should be used under the supervision of a doctor, and common side effects include facial flushing. It is important to note that it is contraindicated for those who are allergic to any of the ingredients of this product, and women who are pregnant should also stop using Triptorelin Acetate.
