Common Questions and Answers about Phentermine and thyroid medication

phentermine

I just got a prescription to start taking phentermine. Can anyone give me some feed back on this pill? What kind of results have you had, how did you take it and how much, did you change your eatting habits? Also I heard this makes you have bad mood swings, has anyone had any problems with it?

Is it OK to use phentermine and levothyroxine together? If not what diet medications are safe to use with levothyroxine? I suffer with such low energy, even though my levels are good.

normally i would have no problem taking something like phentermine, though i my circumstance, where the hyperactivity is gone and i still have my thyroid, i wouldn't want the phentermine to spark another incidence, i don't know that much yet about the recurrence of hyperactivity and if it could happen at all. thanks for sharing, it is giving me hope.

Last year I went to a diet doctor who gave me phenedrine and a thyroid pill called tcl, he said my thyroid was low but my GP said that he was giving me thyroid medication unneccessarily and that it actually showed up elevated when he took blood and I was still on them. He strongly incouraged me not to take them. However they did work and I lost several pounds with proper dieting and excercizing. Without them it was hard to loose anything by just diet and excercize.

Does your daugther have a hypothyroid - slow thyroid? They tested me for thyroid, and my results were borderline for hypothyroid. So the doctor said that I don't need it just yet. But b/c my thyroid is so slow I am having such a hard time losing any weight at all, I wish I had the drug to help me!! Just can't win!!

I have always understood that phentermine should not be taken with thyroid medication. Most times, once the thyroid medication is adjusted properly, weight will come off without aids like phentermine.

I take a number of medications for several illnesses, but the doctor felt phentermine would work best for me. I thought I would never loose weight with the under active thyroid. The 1500 calorie diet and walking on the tredmill 30 minutes a day seems to work. Best of luck to you!

My internist ordered a CT scan and ultrasound to look for fibroids, cysts, etc. Results were one small fibroid. She also tested my thyroid which revealed a TSH of 4.270 and free T4 of 1.12. Initially, she wanted to just retest in 6 weeks. However, I brought her an article from the AACE that recommends treatment over 3.0. She was receptive to this and agreed to start me on 25mcg. Levothyroxine and retest in 6 weeks.

I am 21 yrs old and I have taken phentermine since I was about 17 to loose weight. For some reason I gain weight really easy. So now I don't really loose any weight, so I just take the medication to keep the weight off. If I stop taking it I gain weight really easy, if I take it I don't gain any weight I stay the same, which is my avg weight for my height.

I want to start taking diet pill phentermine (30 mg) 1x a day but I'm also going to be taking synthroid 100 mg 1x day is that safe?

Thanks for responding! I got the perscription for phentermine from a Dr. at a Weight Loss Clinic. The medication was shipped to me from a pharmacy. The numbers on the pills are A 159 split by an indented line. I spoke with the clinic this a.m. and they couldn't figure out why the pills would not be supressing my appetite. I asked if I might return the pills to the clinic and be sent more pills just to see if the problem is with those particular pills. So what do you think?

and about the phentermine pills I have read that most of the people in that program are taking 37.5 once a day around 10:30am or an hour before lunch; right??. Also how long you are in the program; 3 shots a week for a month then off a month or 4 months then a month off?? Last one; is better a 800 or 600 calories/day. Maybe and average would fine but no more than 800?? If someone please can say something different would help a lot to all of us. Thanks.

For the record, I took my 1st phentermine yesterday but not the thyroid. Felt fine all day - was worried about the phentermine making me crazy or jittery or forget about food but it didn't. I think it worked great. I'd been warned that I'd have to force myself to eat but I got light headed and felt hunger enough to eat regularly throughout the day to keep my metabolism up. This was a positive experience.

phentermine does not list thyroid meds or thyroid disease as a caution or a contra-indication, so it should be alright. You don't want to take ANY drugs or vitamins or supplements at the same time as you take your Synthroid. Take your Synthroid with a glass of water in the morning. No food or anything for an hour. Coffee is ok, cream or milk is a major no-no. Some meds or supplements should be spaced several hours later. You can look up drug interactions here; https://online.epocrates.

But you should always confirm all medications with your doctor. Are you on Synthroid for thyroid issues or weight loss? He'd probably keep you on for thyroid problems, but with pregnancy, weight loss isn't safe.

i was using the phentermine37.

Does anyone know the affects with this type of diet and injections in someone who has a thyroid condition. I am on a Synthroid medication at a low dosage. Would I still be accepted on the plan. I have taken the phentermine before, prescribed by my family physician, but had not heard of this combination or of the plan until recently. I have lost apprx. 45lbs, but have been a t a stand still for about 3 months and still need to lose about 60more.

I wonder if I need a higher dose. Were you prescribed any thyroid medication? I was but I'm afraid to take it because of the warnings about not taking it to lose weight and in combination with weight loss drugs. My pharmacist said that if you take it when you don't need it (I've never had a thyroid problem - and I've been tested a lot) it can shut down your thyroid! Any thoughts? Thanks!

She is also a size 4 and has been on phentermine for 2 years...she however did not realize the thyroid med was permanent and often does not take it consistantly due to financial reasons..she often suffers hand tremers etc! I made a appt. with an Endocrinologist who specializes in thyroid, etc. Results, ABSOLUTLY not! Now for my question I feel he is extremely unethical and intend to take this further..Has anyone else ever ran across this problem?

You should separate vitamins/minerals from thyroid medication by approximately 4 hours. This means if you take your second dose of cytomel at 3:00 pm, you could take your vitamins around dinner/bed time. I agree with your endo, not to take cytomel after 3:00 pm because it could likely interfere with your sleep. For fiber, I take Fiber Advance Gummies - they taste good and are fun to chomp on; be careful starting out with them, though; you don't want too much fiber, too quickly.

Levothyroxine is the generic, and most doctors do not like to perscribe a generic thyroid medication, for good reasons. Armour is a natural form of hormones in a combination of T4 and T3. Anyone with thyroid problems should not ingest large ammounts of iodine unless the doctor perscribes it. The iodine will affect your hormone levels temporarily, and that is what you do not want. You want your hormones to be as stable as possible, not shooting up whenever you have a kelp snack.

utahmomma, all of the good medical information I have read including by Dr.Douglas Ross from Boston who is a co-director of thyroid Associates Massachusetts General Hospital and who wrote several articles including for the recent Journal of Endocrinology and Metabolism about predicting cancer in thyroid nodules,says that death from thyroid cancer is under 1%.

I started taking phentermine 30 mg daily on Feb 4, 2009. To date I have not lost a pound. Infact I gained a 2 lbs. I have increased my exercise on my Elliptical (30-60min/day) and started to eat healthier. How long does it take for phentermine to kick in? Any advice? Anything I should say to my physcian?

DO I have a thyroid problem, what I have to take medications for this? I was taking phentermine for almost 1.5 years on and off. Did that have anything to do with my test results? Please help me!

Eli68 - you should try to get new thyroid blood work done, to determine if your medication dosage is too high, or if the palps and anxiety could be from the phentermine. When you get them, you can post the results and reference ranges here for us to further evaluate.

I can't comment on the thyroid concerning med's at all. I do know that you should be questioning the phentermine though. I take BP med's for my blood pressure and went on phentermine ~1 1/2 years ago to loose weight as a last choice thing. I took 1/2 doses due to the incline in my BP and was having chest pains. I did loose 51 pounds in 6 months in which was great, plus full of energy while on it. Though in the last year it has all came back, plus now my energy level has sunk.

I had my thyroid removed a few years back , will B12 shots help me loose weight? Where can I find a doctor ?
