Contraception - tutorial Flashcards
What contraception is recommended to make periods lighter?
NICE CKS:
1. LNG-IUS (Mirena 5yrs, can have smaller 3yr option if difficult to fit)
2. COCP
3. POP/depot
Contraception that can make periods heavier
- Copper IUD
- POP/depot - unpredictable reaction so can make heavier or lighter
- Emergency contraception
Contraceptions to caution in migraine

Long acting contraception options and -ves
- Implant - can cause irregular bleeding, works for 3 years, can get hormonal side effects (eg acne, weight gain)
- IUS - fitting pain, irregular bleeding, can come out - up to 6yrs
- IUD - fitting pain, heavier periods, can come out but 10 yrs lasting usually
- Depot - injection, need every 12 weeks, takes months for fertility to return, direct cause of weight gain (only one found to be direct cause) but do usually stop periods after 6/12, risk of osteoporosis?
What to refer to for contraindications for contraception?
- UK MEC criteria
- Grade 1-4
- Grade 1 and 2 can use

What should patients know about vasectomy?
- Need to use contraception for up tp 12 weeks after procedure - residual motile sperm in vas
- Local anaesthetic, awake, no pain
- Small risk infection
- Permanent - reversal is non NHS and does not always work
- No effect on sex drive/enjoyment of sex, can still get erections and ejaculate
- 2x semen samples taken after procedure to check success and for residual sperm
- No STI protection - may need barrier
Reversal rate vasectomy vs hysterectomy
- All NON NHS
- 75% males if within 3 yrs though, decreases after this (55% within 10, 25% after this)
- Between 50-80% for women, largely depends on age
Failure rate female vs male sterilisation
- Male - 1 in 2000
- Female - 1 in 200
Emergency contraception options
- Levonelle (levonorgestrel) - if within 3 days of UPSI
- EllaOne (ulipristal acetate) - if within 5 days of UPSI
BUT need to have not ovulated
If ovulated:
* Copper IUD within 5 days of UPSI
EllaOne vs Levonelle
- If used within 24hrs, EllaOne is found to be 2.5x more effective than Levonelle
- BUT is much more expensive so Levonelle recommended if within timeframe and not ovulated
Starting COCP post emergency contraception
If used levonelle:
* Can start straight away at same time, wait 7 days until reliable
If used EllaOne:
* wait 5 days to commence - has been shown to reduce effectiveness of EllaOne

- Zig-zag lines in vision
