Effectiveness
How Implanon Affects PatientsEtonogestrel works by blocking the release of a reproductive hormone called luteinizing hormone. This prevents ovulation and makes it harder for sperm to enter the uterus and fertilize an egg. In clinical trials, etonogestrel had a 100% success rate in preventing pregnancy over 3 years. When the implant was removed, normal periods returned within 90 days in 91% of people and fertility returned quickly, with 20 reported pregnancies within 3 months of implant removal. The implant releases 40 mcg of etonogestrel daily and typically provides effective contraception for 3 years. Its failure rate is reported to be 0.
How Implanon works in the bodyEtonogestrel attaches to progesterone and estrogen receptors in the reproductive tract, breast, pituitary, and hypothalamus. This process reduces the production of hormones that control ovulation, resulting in contraceptive effects.

Drug Name
Risk Level
Description
Tranexamic acid
Major
Etonogestrel may increase the thrombogenic activities of Tranexamic acid.
Abacavir
Minor
Etonogestrel may decrease the excretion rate of Abacavir which could result in a higher serum level.
Acetohexamide
Minor
The therapeutic efficacy of Acetohexamide can be decreased when used in combination with Etonogestrel.
Aclidinium
Minor
Etonogestrel may decrease the excretion rate of Aclidinium which could result in a higher serum level.
Acrivastine
Minor
Etonogestrel may decrease the excretion rate of Acrivastine which could result in a higher serum level.
Implanon Toxicity & Overdose RiskThe toxic dose of oral etonogestrel in rats is greater than 2000mg/kg. If a person takes more than one implant, the extra implant should be removed. There is no evidence that etonogestrel is linked to cancer, genetic mutations, or fertility problems.

Implanon Reviews: What are patients saying about Implanon?
5Patient Review
1/19/2017 I had the implant for 2 years and it was great. I decided to get it removed because we are ready to start a family. I had a period almost every 6 months, for a full week, which was really manageable.
5Patient Review
11/8/2016 I highly recommend this form of birth control! I got it inserted with minimal pain and it stopped my period, which was amazing. If you're looking for an effective method of birth control that doesn't require taking a pill every day or dealing with too much pain, this is definitely the way to go!
5Patient Review
1/15/2016 I've had the implant for a little over two years and so far, it's been great! I have very light spotting 2-3 days once every couple of months, but other than that, no period. It's been really nice not having to remember to take something or worry about it falling out.
5Patient Review
9/15/2016 I've been using Implanon for seven years now, and it's fantastic. I love that I don't have to worry about any negative side effects or bleeding.
5Patient Review
4/21/2022 I got the implanon in March 2020 and I'm really happy with it so far. My periods aren't as regular as they used to be, but that's to be expected. The nausea has been tough to deal with, especially after sex, but hopefully it means the implant is working well. Overall, this is the best birth control method I've tried!
5Patient Review
5/1/2022 I've had two implants since 2014 and my third one's term is up in a year. I have light flow that lasts a little longer; it went from 2-3 days to 5-7 days. I haven't had any other side effects that are cause for concern.
4.3Patient Review
10/1/2016 I liked how this product worked in terms of protection, but unfortunately it had some not-so-great side effects. I developed acne and vaginal dryness/swelling/itching, so I'm going to be getting it removed as soon as possible.
4Patient Review
10/12/2021 On average, I bled for seven days with this treatment and my menstrual cycle shortened to 23-26 days.
3Patient Review
11/13/2019 I had an implant put in November 2018, and by January 2019 I started having severe headaches. In March, my eyesight also began to deteriorate--at first I thought it was just from staring at a computer all day, but it turns out the pressure the implant was putting on my brain was causing my optic nerves to swell. So if you're experiencing any of these symptoms, please go see a doctor.
2Patient Review
11/5/2018 Since I began this treatment, I've noticed some unwanted side effects like tingling in my breasts and back, as well as spotting and breast tenderness. I'm not sure if it's just anxiety though. Has anyone else experienced anything similar?
1Patient Review
5/16/2022 This medicine ruined my life. I had to endure 15 years of abuse because of it, all because the doctor asked my wife if she wanted it when she was just 19 years old. My family is destroyed because of this drug, and I will never forgive those who created it.
