Quick Start Contraception
Quick Start refers to starting a method of hormonal contraception outside the usual recommendation of commencing on days 1–5 of a cycle. The principles are:
- start active contraception immediately
- use barriers or abstinence until the method becomes effective (seven days for most methods; 48 hours for progestogen-only pills)
- do a pregnancy test in four weeks.
Quick Start is suitable for all types of contraception except intrauterine devices.
Causes of irregular vaginal bleeding on contraception
pregnancy, medication interactions, cervical cancer, endometrial cancer and endometrial polyps
Management of irregular vaginal bleeding on contraception
Depending on the patient’s wishes and the absence of contraindications to medications, the following management options can be tried:
Wait and see if the bleeding settles
Trial a combined hormonal contraceptive for three months
Trial a five-day course of nonsteroidal anti-inflammatory drugs such as mefenamic acid 500 mg twice to three times daily
Trial a five-day course of tranexamic acid 500 mg twice daily, particularly if bleeding is heavycommence another method and remove the implant once the new method is effective.
Other options with lower levels of evidence for their effectiveness include:
norethisterone 5 mg three times daily for 21 days
levonorgestrel progestogen-only pill, 30 µg twice daily for 20 days
early replacement of implant.
Complications of IUD insertion
infection occurring in the first three weeks after insertion (approximately one in 300 people)
non-insertion (due to excessive pain or technical factors)
perforation of the uterus (1–2 in 1000 people)
malposition of the IUD.
