Recombinant FSH + LH Pregnancy: There is no indication for use during pregnancy and it is not indicated during breast-feeding. Data on a limited number of exposed pregnancies indicate no adverse reactions of follitropin alfa and lutropin alfa on pregnancy, embryonal or foetal development, parturition or postnatal development following controlled ovarian stimulation; no teratogenic effect reported in animal studies, but clinical data are not sufficient to exclude a teratogenic effect in case of exposure during pregnancy.

Follitropin alfa with lutropin alfa

Brand names: Pergoveris

A combination of recombinant follicle-stimulating hormone (follitropin alfa) and recombinant luteinising hormone (lutropin alfa) given by subcutaneous injection to stimulate follicular development in women with severe gonadotrophin deficiency undergoing assisted conception or ovulation induction.

Auto-extracted from the source labelling — not yet independently clinician-verified. These values were distilled from the UK SPC (or the US label where noted) but have not had a clinician sign-off. Confirm against the current SmPC before prescribing.

Adult dose

Dose: One vial of Pergoveris (150 IU follitropin alfa with 75 IU lutropin alfa) daily
Route: Subcutaneous injection
Frequency: Once daily, as a course of daily injections
Indication in the fetched SPC: LH and FSH deficient women, to promote follicular development followed by final maturation after hCG. Treatment must be initiated under the supervision of a physician experienced in fertility disorders. If the patient is amenorrhoeic and has low endogenous oestrogen secretion, treatment can commence at any time. SPC §4.2 verbatim caution: 'If less than one vial daily is used, the follicular response may be unsatisfactory because the amount of lutropin alfa may be insufficient.' Tailor to the individual patient's response, assessed by follicle size on ultrasound and oestrogen response. If an FSH dose increase is deemed appropriate, adapt preferably after 7 to 14 day intervals and preferably by 37.5 to 75 IU increments USING A LICENSED FOLLITROPIN ALFA PREPARATION (i.e. added as separate FSH, not by increasing the number of combination vials). It may be acceptable to extend the duration of stimulation in any one cycle to up to 5 weeks. FINAL MATURATION: when an optimal response is obtained, a single injection of 250 micrograms r-hCG or 5 000 IU to 10 000 IU hCG should be administered 24 to 48 hours after the last Pergoveris injection; coitus is recommended on the day of and the day following hCG, or intrauterine insemination / another medically assisted reproduction procedure may be performed. Luteal phase support may be considered, since lack of luteotrophic activity (LH/hCG) after ovulation may lead to premature failure of the corpus luteum. If an excessive response is obtained, stop treatment and withhold hCG; recommence in the next cycle at a lower FSH dose. ADMINISTRATION: the powder should be reconstituted immediately prior to use with the solvent provided; the first injection should be performed under direct medical supervision; self-administration only by patients who are well motivated, adequately trained and with access to expert advice. No relevant indication in the elderly; no relevant use in the paediatric population.

Dose adjustments

Renal

Safety, efficacy and pharmacokinetics in patients with renal or hepatic impairment have not been established (SPC §4.2 Special populations). No dose adjustment is stated.

Dose auto-extracted from UK Summary of Product Characteristics (SPC) via the eMC; US FDA prescribing information (openFDA / DailyMed) — cross-check; US labelling may differ from UK — not yet clinician-verified. Always confirm against the product SmPC and your local formulary before prescribing.

Contraindications

  • Hypersensitivity to the active substances or to any of the excipients
  • Tumours of the hypothalamus and pituitary gland
  • Ovarian enlargement or ovarian cyst unrelated to polycystic ovarian disease and of unknown origin
  • Gynaecological haemorrhages of unknown origin
  • Ovarian, uterine or mammary carcinoma
  • Must not be used where an effective response cannot be obtained: primary ovarian failure; malformations of sexual organs incompatible with pregnancy; fibroid tumours of the uterus incompatible with pregnancy

Side effects

  • Headache (very common)
  • Ovarian cysts (very common)
  • Mild to severe injection site reactions — pain, erythema, haematoma, bruising, swelling and/or irritation (very common)
  • Breast pain, pelvic pain, and mild or moderate ovarian hyperstimulation syndrome (common); severe OHSS (uncommon)
  • Abdominal pain, abdominal distension, abdominal discomfort, nausea, vomiting, diarrhoea (common)
  • Thromboembolism usually associated with severe OHSS, and mild to severe hypersensitivity reactions including anaphylaxis and shock (very rare)

Clinical monograph

How it works

Follitropin alfa stimulates ovarian follicular growth and granulosa-cell oestrogen production, while lutropin alfa supports follicular maturation and theca-cell androgen substrate supply, together mimicking physiological gonadotrophin drive.

Prescribing in practice

  • Ovarian hyperstimulation syndrome is the key risk, potentially severe with fluid shifts, ascites and thromboembolism, so treatment must be individualised with ultrasound and hormonal monitoring under specialist supervision.
  • Multiple pregnancy risk is increased with gonadotrophin stimulation and should be discussed and minimised by careful cycle monitoring.
  • This combination is reserved for women with significant LH as well as FSH deficiency and is initiated only within specialist reproductive medicine services.

Monitoring

Monitor ovarian response with serial transvaginal ultrasound and serum oestradiol to titrate stimulation and detect early hyperstimulation.

Counselling the patient

  • Report abdominal swelling, severe pain, breathlessness or reduced urine output promptly, as these can signal ovarian hyperstimulation.
  • You will be taught how to give the injection under the skin and how to rotate sites.
  • Attend all scan and blood-test appointments so the dose can be adjusted safely.

Evidence & guidelines

Use is supported by NICE fertility guidance and the SPC, which recommend specialist monitoring to balance follicular response against the risks of hyperstimulation and multiple pregnancy.
