Synthroid medication causing hair loss

Taking the medication Synthroid has caused me to suffer a severe hair loss.  What would be the result if I stopped taking Synthroid?

if you are HYPO then you need some sort of thyroid replacement -- hair loss is a symptom of HYPO and it may be that you need mroe time with adequate replacement - may take 2-3 months at a target TSH of about 1.0 to see improvement in hair/nail changes

Don't stop your medication without your doctors knowledge and approval.  This can cause a big set back among other possible problems.

It is not the Synthroid but rather the disease process.  A lot of thyroid patients have suffered hair loss or thinning. Hair loss or thinning is just one of the many thyroid symptoms.

Once you are on the right level for you to feel your best hair loss will subside and grow back.

Some have found certain shampoos help but I never had this problem so never paid attention to the brands.  Perhaps others will come along with that info.  

Good Luck.

I was on 200 mcg and that's when the hair loss became severe.  Reported it to my doctor.  He did another blood test 8 weeks ago and reduced my Synthroid to 150 mcg.

I had really bad hair loss right before being diagnosed with Hashimoto's.  In fact, the hairloss is was drove me to see a dermatologist who did some blood work and checked my TSH levels.  It took about a month of using the Synthroid before the hair loss subsided.  Hang in there.

Hey, I am having the same thing happen right now.  I am scheduled for thyroid scan on the 21st.  Found two nodules on my thyroid.  Been taking meds for several years - just started having these problems.  I went to the pharmacy to get some rogaine but my pharmacist said that I should just stick it out until we get my thyroid problems taken care of.  I have always had really thick healthy looking hair - so I am really upset about my hair loss.  I get handfuls of it out of the shower drain!  I wish you lots of luck - just wanted you to know that I sympathize.

I've read on several sites that there can be initial hair loss with Synthroid.

I also had extreme hair loss with hyperthyroidism. And doesn't seem to be improving that much with treatment. It was so bad I* had to wear a wig. :-(

Hey guys it happened to me too but after 2 months on euthyrox-levothyroxine my hair grew back thicker than I have had for 24 years. I switched to pantene hair products too as I heard that cancer patients use it after radiation treatments and it helps .  It works for me. Always remember you are beautiful even without hair.

Due to insurance issues I haven't been on my synthroid for about 6 years. (I have hypo. by the way) My thyroid corrected itself during pregnancy so it wasn't an issue for a while. Now I have found that if I use pantene conditioner and take prenatal vitamins my hair, nails and skin issues are better. Good luck to you!

Hi friends,

I have hypothyroid as well and have been taking synthroid for 17yrs now.  I also experienced some thinning of the hair and also quite some hair loss in the past few years....it was getting pretty bad at onepoint but then slowly recovered.  I defintely do NOT have my same hair but at least some grew back although it is still very thin.  Thansk for the Pantene shampoo advice!  I will give it a try.

My hair loss is so bad that I've considered just shaving all my hair off.  Because I'm female it would be a little wierd.  I don't know what else to do.  I'm 28 and have longer hair, but have to put it back every day so I don't get hair all over.  Every day seems to be worse than the day before.  Today I pulled out a HUGE chunk of hair when I was washing my hair.  I already use pantene, so I don't know what else to do.  I've been on Synthroid since my cancer treatment in April and still no luck on getting it regulated.  HELP!!!!
