Ovitrelle is a medicine containing recombinant hCG and is administered to women in order to trigger ovulation during a cycle of artificial insemination, in vitro fertilisation or ICSI.

Composition

Its active substance is choriogonadotropin alfa, also named recombinant hCG, human choriogonadotropin. The name recombinant means that it has not been purified using human substances. On the contrary, it is synthesised in the laboratory using genetic ingeneering techniques and its origin is artificial.

Apart from its active substance, alfa choriogonadotropin 250 mg per 0.5 ml, as excipients, manitol 27,3 mg , L-methionine 0.1 mg and 0.5 mg of poloxamer 188 can be found.

Generally, Ovitrelle is available in two formats:

Usage instructions

The administration of Ovitrelle is carried out subcutaneously, i.e. injected under the skin. Prefilled syringes are of only one use and must only be administered if the solution has dissolved completely and no suspended particles can be observed.

Its administration is simple, but normally the medical staff of the clinic tend to administer the first dose to show the patient how to use it. It can subsequently be administered at home. The patient can do it himself or a family member can help her.

It’s important to fully read the information pamphlet of the medication before preparing or injecting it. If any doubts arise, the best is to ask them to the medical staff.

Contraindications

In some cases its usage is not recommended:

  • Allergy to the active substance or its excipients.
  • Tumours of the ovaries, uterus or breasts.
  • Vaginal haemorragia of unknown origin.
  • Cysts in the ovaries not caused by the ovarian polycystic syndrome.
  • Ectopic pregnancy.
  • Pregnant women and women that are breastfeeding.

Adverse reactions

The administration of Ovitrelle may have undesired side effects. The most common are:

  • Gastro-intestinal alterations, such as vomits and nausea.
  • Swelling or abdominal pain.
  • Local reactions in the area of the injection.
  • Headaches.
  • Tiredness.
  • Mild or moderate Ovarian Hyperstimulation Syndrome.

Ovitrelle and embryo transfer

Ovitrelle is a drug of choice for triggering ovulation in case the hormones allow the embryo transfer to be performed during the cycle you are in, that is, egg retrieval, egg fertilisation and transfer into the womb after three of five days.

There are also other medicines to trigger ovulation affecting the endometrium. In addition, these medicines do not allow the transfer to be performed after five days. Instead, embryos are frozen until the next cycle, when they are thawed and prepared for implanting after optimising endometrial receptivity.
