anastrozole or letrozole

Gave me symptoms. I am now on letrozole. Also experiencing symptoms. Will letrozole keep this cancer away. Is there a smaller does than 2.5 of letrozole that I can take.

It seems there are quite a few posts under Pediatric Endo forum but not able to find any answers if any parents tried Anastrozole/Letrozole and what has been their experience regarding delaying bone age and side effects. I will appreciate if any parent with experience of using Anastrozole for their kids may share their experience.

Please discuss with your treating doctors, the option of switching aromatase inhibitor therapy to one of the other agents, such as Femara (Letrozole) or Exemestane (Aromasin), to determine whether you would better tolerate these other drugs. I wish you well and I hope that something can be done to alleviate your discomfort....

December 14, 2009 (San Antonio, Texas) — New results coming from 2 mature trials with exemestane (Aromasin, Pfizer) suggest that this aromatase inhibitor differs slightly from the other 2 available products, letrozole (Femara, Novartis) and anastrozole (Arimidex, AstraZeneca). Although all 3 are aromatase inhibitors, exemestane is a steroidal product that binds irreversibly to the estrogen receptor; the other 2 products are both nonsteroidal and are reversible inhibitors.

(beyond the initial 5 years) is with letrozole (Femara) after 5 years of tamoxifen. Letrozole and anastrozole (Arimidex) are both aromatase inhibitors and are very similar to one another. In most of the adjuvant studies using these drugs, 5 years of treatment has been given. An ongoing study will compare 5 to 10 years of aromatase inhibitors but there are no results available yet on that study.

I am 63 and just diagnosed with Stage 1, ER/PR Positive, node negative invasive ductal carcinoma. My oncologist is in the process of deciding whether to prescribe Letrozole/Femara or Anastrozole/Arimidex. What considerations factor into which of these two drugs to use? Has anyone had experience with either of them? How serious are the side effects?

I was diagnosed with stage 2 er+/pr+ breast cancer with lymph node involvement in November of 2011. I am 43 years of age. I had a mastectomy with lymph node dissection. I received 4 treatments of Adriamycin and Cytoxan, then 12 treatments of Taxol, followed by 33 radiation treatments. I am currently taking Anastrozole. My ob/gyn wondered why they didn't want me to have a total or partial hysterectomy. Should I do this. Am I at high risk for cancer of the ovaries or uterus?

Have developed a heart rhythm disturbance, shortness of breath, edema of hands and legs/feet since being on Anastrozole. How worried should I be? Should I consider discontinuation discussions with my Dr.? This discussion is related to <a href='/posts/show/542261'>Can Arimidex Cause Skin Lesions?</a>.

If her cancer is hormone responsive (you can ask her doctor to verify this), she may benefit from taking hormonal treatment like anastrozole, letrozole, or fulvestrant, instead of receiving chemotherapy.

im on anastrozole.

Has anyone ever used Letrozole? Was it beneficial? Did you get a BFP? Any side effects?

If you've had Hashimoto's for that long, have you also been on any replacement thyroid hormone medication? If so, what medication, dosage and for how long? Have you had Free T4 and Free T3 tested to determine actual thyroid hormone levels? If so, what are their results, with reference ranges? I've read that there's a connection between breast cancer and thyroid disease, but I'm not exactly sure what it is.

Hi! Doctors will prescribe either clomid or letrozole to assist with ovulation. There's two main differences: it doesn't have anti-estrogenic side effects like clomid; and although studies have proven letrozole is an effective fertility drug it hasn't been approved by the FDA yet for fertility use, thus isn't covered by insurance (beware it's very expensive). Letrozole was developed to treat estrogen-sensitive breast cancers.

I have been on letrozole for 5 months now and nothing.I had a miscarriage in march and have been taking this since march.The only side effects I have had are hot flashes in the beginning but I do get stabbing headaches occasionally.Has anyone else had to go from letrozole to something else that helped get them pregnant.

As of right now we are holding off on meds. He is growing but still just a little each year. He hasn’t hit a growth spurt yet but I’m hoping he does very soon. My son is 4’6” now and I worry so much that he is not going to reach anywhere near his mid parental height. How tall is your son? We have seen an endocrinologist who thinks anastrazole would be a good way for him to get closer to his potential, but I am so scared to put him onedicines just to gain a few inches.

Hello, my husband and I have been trying to conceive since we've gotten married 8 yrs ago. I was diagnosed with pcos (polycystic ovarian syndrome) in 2006. I'm not overweight, and my cycles come every month but not consistently. Well, this entire month of Nov., I have not gotten my period. I thought I might finally be pregnant so I went to my dr. and the test was negative. How can this be?? I get my period every month, finally miss a cycle, and it's negative?

My son is on GH for GHD. Also did 2.25 yrs anastrozole since bone age was slightly ahead. Now only on GH. Age 15.5, bone age 13.5-14. Has all the puberty markers for tanner 4: pubic hair now starting a line to navel. Has to shave a couple times per week but only few hairs in beard area, voice deeper but no prominent adams apple yet. A year ago at endo appt we were told he didnt have to endure anymore testicle size checks. I assume that means they are near adult in size.

well i recieved my negative beta today and they want me to do a cycle of letrozole or femara which is an oral pill simliar to clomid.. my question is has anyone ever tried this med before, any side effects and any success..

Has anyone ever used Letrozole? Was it beneficial? Did you get a BFP? Any side effects?

Letrozole is effective in increasing final adult height. Many medical studies have shown that. Most doctors don't know it yet. The recommended dose of 2.5 mg is actually not necessary. 0.3 mg will provide similar effects.

Anyone get pregnant using femara/letrozole after being given unexplained infertility diagnosis? How many months did you take it before you got your positive? Me: 28 Hubby: 30 Sperms analysis perfect, laparoscopy perfect, all tests for ovulation and ultrasounds looked perfect. Trying since 2012 no pregnancy yet This is my 2nd cycle on femara, next ovulation expected on 1/14. If 3rd cycle not successful, will do iui with femara anyone else done this and got pregnant? ?

I finally broke down after 26 mo of TTC, 8 clomid cycles, 2 IUIs and trigger shots and went to the RE for advice. After AF shows in 2 weeks or so - we will start on letrozole with CD3 blood work and U/S and then do another IUI. If that is unsuccessful - we will do IVF. Has anyone done letrozole vs clomid? side affects? BFPs?
