Effectiveness
How Synarel Affects PatientsNafarelin is a drug that works to stimulate the pituitary gland to release hormones, LH and FSH, which in turn lead to a rise in gonadal steroid production. Taking this drug twice a day lead to decreased gonadal steroid levels after about 4 weeks. When the treatment is stopped, normal pituitary and ovarian function is restored, and the levels of estradiol return to the pre-treatment levels. It should be noted that endometriosis may return after stopping any hormonal therapy or surgery that leaves the ovaries and/or uterus intact.
How Synarel works in the bodyNafarelin works by blocking the GnRH receptor and decreasing production of hormones like estrogen and testosterone. This leads to a decrease in secondary sexual characteristics in children, a dramatic decrease in the hormones that cause endometriosis, and the suppression of growth in children. When nafarelin is stopped, hormone levels usually return to what they were before treatment.

Synarel Reviews: What are patients saying about Synarel?
4.3Patient Review
2/22/2017 This is the only treatment that has given me any relief from my endometriosis. I've been using it for three months now, and it's really helped. However, under the new insurance program, I won't be able to afford it.
3Patient Review
5/15/2014 This was my doctor's go-to recommendation for endometriosis after two surgeries. It took a little while to start working, but it completely changed my life for the better. I was pain-free for three years – something I hadn't experienced since I was a preteen. Unfortunately, when my original prescribing doctor retired, their replacement refused to let me continue taking it because they said I had been on it for too long (six years). Just a few short years later, I ended up getting a complete hysterectomy. If only I could have stayed on the Synarel!
2.3Patient Review
2/19/2014 This treatment caused me severe sinus pain, and I developed ringing in my ears after using it for just two weeks. The ringing/fuzzy sound is still happening even after stopping the spray five weeks into the course.I have stopped using it and, two weeks later, I am still having trouble hearing over the noise in my ears. It did start to ease some of my abdominal pains but, overall, this was a very unpleasant experience.
1Patient Review
5/8/2010 Do not use this medication under any circumstances. It caused me debilitating, long-term depression and I will never be the same.

Answered by AI
How quickly does Synarel work?
"For that reason, you need to take it as an intranasal spray two to three times a day, starting two to three months before you want your periods to stop.
Reduced oestrogen levels will usually be observed after one month of taking Synarel, in the form of either stopped or reduced periods. Synarel needs to be absorbed into the bloodstream in order to be effective, so it is administered as an intranasal spray two to three times a day, ideally starting two to three months before periods are desired to be stopped."
