Treatment Info
Condition / reason:   hypothyroidism
Dosage & duration:   100mcg (dosage frequency: once daily) for the period of still taking since 10 years on
Other conditions:   none
Other drugs taken:   none
  
Reported Results
Benefits:   Clearer thinking; improved outlook and energy level.
Side effects:   I have had a persistent cough since taking this drug.
Comments:   Taken first thing with glass of water and no food for 30 minutes. Doctor did not see the connection between cough and Synthroid,(chest Xray came back fine) however as it did bother my stomach briefly at time of dosing, I decided it might be affecting the stomach lining. Recently towards late afternoon or before retiring will take Tagamet or some generic stomach med. I DO NOT experience heartburn, however, this routine seems to reduce the embarrassing cough significantly. This was my own resolution after trying many allergy medicines once or twice which did not stop the cough at all. Was also given sample of Advair which I did not use due to negative side effects I read about on internet before using. I am seeking a more natural and effective solution to replace the Synthroid with something that will treat source of low thyroid as well as the symptoms.

Dosage & duration:   various over lifetime, currently 75mcg (dosage frequency: once a day) for the period of 25 years
Other conditions:   none
Other drugs taken:   none

Benefits:   Synthroid replaces the thyroid hormones not manufactured by the body. When proper levels are achieved, the endocrine system operates as it should. Important to note that generic versions CAN NOT be substituted if patient is currently treated with name brand. Start on generic, stay on generic. Start on Synthroid, stay on Synthroid. This is common knowledge among endocrinologists and pharmacists, but your insurance company may interfere.
Side effects:   Provided annual blood tests are administered to check thyroid levels, there are no side effects and ensures healthy operation of endocrine system.
Comments:   Treatment includes annual blood test to monitor thyroid levels, adjust dosage if necessary, and annual check-up with endocrinologist or internist.

Synthroid review by 40 year old female patient

Overall rating:  
Effectiveness:   Moderately Effective
Side effects:   Mild Side Effects
  
Treatment Info
Condition / reason:   hypothyroidism
Dosage & duration:   200 mcg (dosage frequency: daily) for the period of 11 years
Other conditions:   iron-deficiency anemia, metrorrhagia
Other drugs taken:   ferrous sulfate
  
Reported Results
Benefits:   The synthetic thyroid hormone treatment made it so I was at least able to function, sped my metabolism up enough to keep warm and have regular menses.
Side effects:   Side effects come from taking either too little or too much Synthroid. It is a tightrope balancing act and the blood work is not specific enough to guide the clinical course.
Comments:   Compared to others who naturally have a functioning thyroid, it is clear to see that Synthroid is an inferior product to what the thyroid makes naturally in a healthy individual. I know that I still have minor hypothyroid symptoms even when my blood counts show that I have therapeutic levels of the medication. Additionally, generic versions of Synthroid seem to be even less effective at relieving all the symptoms, even though the blood counts could be normal. With hypothyroidism becoming a very common condition these days, one would think that new medications would be coming out, but the medical professionals seem content to stick with Synthroid because "on paper" it seems to be safe and effective.

Treatment Info
Condition / reason:   weight gain
Dosage & duration:   .05 now .15 (dosage frequency: once a day) for the period of 17 years
Other conditions:   none
Other drugs taken:   none
  
Reported Results
Benefits:   Initially, I was concerned because I had knee surgery and was on crutches for six months. I gained weight rapidly and didn't know why. After taking a blood test, it was determined that my thyroid level was low. Once taking the medicine, my blood tests came back ok, but the weight did not decrease as the doctor had said it would.
Side effects:   There have been no side effects to my knowledge. I do realize that if I do not take the medicine as indicated that I get tired more frequently and feel slugish. I am concerned that there may be a better alternative to taking synthroid. I have heard of medicine that can be taken in two pill form and that may better correct the thyroid imbalance.
Comments:   I take one pill everyday at the same time.

Benefits:   Increase in energy, immediate weight loss.
Side effects:   None noticable.
Comments:   I had long complained of fatigue, listlessness, disinterest. I exhibited classic symptoms of hypo-thyroid, but did not check out as such in the standard blood test. A new doctor understands that not every person will fall within "standard" test results. God bless her. The results were rapid and positive with an increase in energy, loss of about 10 pounds of excess weight.

Condition / reason:   Hypothyroid
Dosage & duration:   175mcg (dosage frequency: once/day) for the period of 10 years
Other conditions:   being a menopausal and postmopausal woman
Other drugs taken:   none
  
Reported Results
Benefits:   better mental acumen, energy,hair texture,better physical endurance and strength
Side effects:   I would not term the effects as negative side effects, nor would I say they the effects were as beneficial as I expected them to be. 10 years later and I am still suffering the same symptoms, though not as severe. I have had a very difficult time getting traditional Dr.s to look beyond the Thyroid and to realize that for a woman it becomes a package deal. Once you hit menopause and the chemical balance shifts it is not enough to look at one part of the body and blame that for all your symptoms. I was NEVER sick as a child or young adult. I never had female problems, but once menopause set in my body went haywire. I KNOW, in speaking with women my own age,that I am not an isolated case. Thyroid disease is more prevalent than ever and this drug does not cut it for some patients.
Comments:   One pill every morning 1 hour before breakfast. Just recently instructions have included not taking vitamins with Calcium 2 hrs after the pill, but this has not made a difference.

Reported Results
Benefits:   with the treatment I feel less tired and more energetic.I comeback to my normal weight and I stop losing my hair. Also I do not get cold as I use to.
Side effects:   I did not have any side effects after the doctor find the right dosage I was able to function like I used to before I have the symptoms of the hypothyroid.
Comments:   I take one tablet everyday in the morning in a empty stomach around the same time and I wait an hour before I eat. Sometimes I can only wait 30 minutes and it does not seems to alter the effect of the medication.

Side effects:   I experienced no discernible side effects.
Comments:   Although this drug did alleviate my hair loss it only lessened my depression, exhaustion, and weight gain. I still have difficulty with concentration and memory and experience "brain fog" every day. My endocrinologist says my dose is perfect based on my blood test results but my symptoms persist.

Treatment Info
Condition / reason:   low under active thyroid
Dosage & duration:   .05mg taken one a day for the period of still taking
Other conditions:   n/a
Other drugs taken:   n/a
  
Reported Results
Benefits:   I became more active and lost 10 of the 14 pounds I had gained. I have more energy, and feel like myself again.
Side effects:   I never had any side effects. The only drawback is that you have to take the medication on an empty stomach or wait three hours after you eat. However, they prefer you take it in the morning. So what I do is keep my medicaton next to my bed and take it the very first time I wake up in the morning whether it's 4, 5, or 6 am.
Comments:   I returned from vacation in August by November I had gained 14 pounds. I did not know why. I was eating the same amount of food. I went to see the doctor and after a complete check up and blood tests they found I had a low under active thyroid. As I think back, I did feel more tired, I did not want to join my kids and spouse to do anything instead I would go to bed early. That is not like me. I am the type of person who would get up and go anytime. I thought I was just tired. Now, I reflect and remember that I stopped doing things with my family, became less active and all along I thought it was because I was tired when in actuality my thyroid was off.

Treatment Info
Condition / reason:   Thyroid cancer
Dosage & duration:   100 mcg (dosage frequency: once a day) for the period of 8 years and continuing
Other conditions:   None
Other drugs taken:   None
  
Reported Results
Benefits:   The treatment benefits of taking Synthroid have everything to do with metabolism regulation. Because I had thyroid cancer the entire thyroid was removed. Since thyroid hormone keeps the body running at optimum speed, it is now essential for me to take medication that will accomplish what my body is no longer capable of doing on its own.
Side effects:   There have been no treatment side effects for me thus far.
Comments:   Treatment consists simply of taking a 100 mcg Synthroid pill each morning. This should be taken on an empty stomach and no food should be taken for one full hour. It is also important not to take any calcium supplement for four hours after taking Synthroid. Calcium interferes with the body's ability to effectively utilize the Synthroid.

Reported Results
Benefits:   Increased energy, ability to focus, and increased ability to lose weight. Patient suffered fewer low blood sugar episodes. Thirty pounds of weight were lost in the first year.

Comments:   Patient has Hashimotos disease. Prescribed synthroid. Patient also working to follow a low carb diet, regular exercise, and normal sleep. Over time, synthroid dosage has increased, to 112 mcg per day from the original dose of 50. This is some cause of concern re: progression of the disease, but so far, no alternative approach/therapy seems to counteract this progression. Blood work required every 6 months in order to help ensure proper dosage.

Dosage & duration:   100 mcg (dosage frequency: once daily) for the period of to the present time
Other conditions:   None
Other drugs taken:   None
  
Reported Results
Benefits:   Treatment benefits consisted of weight gain after pronounced weight loss due to thyroid tumor. Although the patient felt that there was a greater weight gain than she desired.
Side effects:   A greater than desired weight gain and a decrease in energy and libido are the most bothersome side effects as per the patient. The dose is still being titrated in order to moderate these effects.
Comments:   Post thyroidectomy, the patient was placed on Levothyroxin 120 mcg, but the patient complained of pronounced weight, lack of energy, lack of sex drive and some depression. Blood work was done and the dose has been adjusted to 100 mcg and will be re-evalutated in 2 months.

 

Synthroid review by 44 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   No Side Effects
  
Treatment Info
Condition / reason:   Hypothroidism after radioactive iodine
Dosage & duration:   .125 mcg (dosage frequency: once daily and twice on sunday) for the period of 16 years
Other conditions:   Graves Disease - headaches racing heart
Other drugs taken:   multivitamin with Iron
  
Reported Results
Benefits:   Medications for the graves disease were not keeping the thyroid levels at a constant state. Had to continually change dosage. The medication for hyperthyroid also can cause birth defects. I was anticipating having children within a few years. I went in and had the radio active iodine. After one month my thyroid was destroyed. Had tried generic brands of synthroid but was still expereincing changes in my thyroid level. My doctor perscribed only name brand syntroid and it has been at a cosistant level for at least 5 years.
Side effects:   When taking synthroid it must be taken on an empty stomach around the same time every day. Multivitamins with Iron decrease the sythroids effectiveness so they must be taken at least 3 hours after taking sythroid. Never miss a dosage. I once missed a few days in a row and became very depressed almost suicidal. Will need to take sythroid for the rest of my life and keep regular appointments to have my thyroid levels checked.
Comments:   The radio active iodine treatment was conducted as outpatient surgery at the local hospital. I was given a pill to swallow. I was then asked to come back after 6 hours to have a scan done of my thyroid. I came back the next day for another scan. After one week I had a blood test and was perscribed synthroid. I have my thyroid checked on an annual basis. In some cases depending on any changes in my thyroid levels I have had to go back on a six month check up schedule.

Overall rating:  
Effectiveness:   Marginally Effective
Side effects:   Moderate Side Effects
  
Treatment Info
Condition / reason:   Hypothyroidism
Dosage & duration:   0.15mg taken one every day for the period of continuous until age 40
Other conditions:   none
Other drugs taken:   none
  
Reported Results
Benefits:   This dosage was supposed to help the thyroid function correctly. However, it appeared to make me more lethargic, even though the blood test showed that it was working correctly. I experienced more benefit from exercise than from taking this mandatory drug.
Side effects:   I experienced weight gain fluctuations and loss of energy. I complained to several doctors over the period of 20 years without effect. There is no alternative treatment if the patient does not feel the benefit. The doctor only sees the blood test to show that the treatment is effective.
Comments:   No treatment, other than taking a blood test every 6 months to see if the level was correct, regardless of the side effects. I found this offensive since I clearly gained 20 pounds when on the medication than when I was not on the medication (or the dosage was reduced).

Benefits:   Synthyroid replaces thyroid hormones that provide energy and increase your metabolism. I had a small goiter that was diminished when I began taking the medicine. If I miss a few days I have very little energy and feel as if I'm carrying heavy suitcases around.

Other conditions:   None
Other drugs taken:   None
  
Reported Results
Benefits:   Having been diagnosed with hypothyroidism when I was only twenty, I was administered varying levels of Synthroid. Prior to taking the medication, my hypothyroid condition was so severe that my metabolism was adversely affected. Not only did I feel sluggish, but my liver was even slow to act because I started turning orange! My fingertips were calloused, my speech was slurred and my hair had begun falling out. When the first dosage was given, it was too high. Then when it was adjusted and my blood levels determined that it was the right amount, the symptoms all began to subside and slowly I became functional again. I don't normally take any over-the-counter medications but as for this prescription medication, I need it to effectively manage my hypothyroidism.
Side effects:   Initially, when the dosage given to me was too high, I became a little jittery. If the doctor prescribes the right dosage for you, there should be minimal to no side effects at all.
Comments:   Synthroid (generic name: Levoxyl) is taken once a day, preferably in the morning on an empty stomach. There do not seem to be any extra details concerned with the daily administration of the drug.

Contraceptives MIN-OVRAL and supplements of Ca, Mg and iron were taken at the evening to avoid the interractions.

Benefits:   The drug Levothyroxine 100 mics daily that I took for hypothyroidism was advantagious for my metobolic effect. I did have more energy and felt more alert and awake, as before where I felt lithargic and brain dead.If I inadvertantly skipped a day of medication, I felt like I would notice my sluggishness a few days later.
Side effects:   I had no side effects.
Comments:   I have since stopped taking the Levothyroxine 100 mics daily. My provider explained to me since I was still feeling tired was to switch to the brand name Synthroid 100 mics daily. I have noticed a big difference in my energy level and alertness. I can't believe I have gone this long (15 years) feeling tired and out of sorts. I wish now I had been taking the brand name all along. No telling what things I may acomplished.

Condition / reason:   Hashimoto's Thyroiditis
Dosage & duration:   75 mcg (dosage frequency: daily) for the period of almost two years now
Other conditions:   initially high blood pressure
Other drugs taken:   initially, toprol
  
Reported Results
Benefits:   Most importantly, my blood pressure went back down to normal when my heart rate rose to a more normal level. I was then taken off the topral and my blood pressure has remained at a good level. Additionally, my hair stopped falling out and wasn't as dry. Also, my skin improved. Before the medication, my skin was horribly dry and flaky. The changes did not take place overnight. I would say that it took about 3-4 months to see any improvement in my hair and skin.
Side effects:   I really experienced very few side effects, if any. Initially, they started me off on a very low dosage because they just thought it was simply hypothyroidism but after a blood test, they realized that I has Hashimooto's thyroidities and moointored it more closely. At low dosages, there wasn't much improvement in my symptoms. I do have excessive sweating but they aren't sure if that is the synthroid or menopause and the doctors don't really seem concerned.
Comments:   Initially I was being treated for high blood pressure and put on topral but they did a TSH test and realized that something was wrong with my thyroid. I was originally started off on a very low dosage ( 12.5 mcg/daily) and had to keep going back for blood work every month. Slowly they increased it until they did another test and found out that it was Hashimoto's thyroiditis. At that point, they increased the dosage to 75 mcg/daily and so far it has worked out but I do have to keep having the TSH levels checked.

Reported Results
Benefits:   Had to take a thyroid replacement, so it did that, but not as well as I would have expected.
Side effects:   Was very tired, had memory problems, weight gain. Had trouble moving around, joint pain.
Comments:   Synthroid was prescribed as thyroid replacment hormone after total Thyroidectomy due to nodules, etc from Graves disease. Was determined that 75 mcg was the correct dose. However after 2 years of taking Synthroid and endocrinologist unwilling to try alternative medication, I found another doctor who did some additional testing. She found that I was low in Free t3 & t4 and the prescribed Armour thyroid. I feel much better on this thyroid replacement than I did using Synthroid.

Reported Results
Benefits:   I had Graves disease in 1990 which indicated that my thyroid function was way too high. The symptoms were anxiety, sleeplessness, depression and restlessness. I was administered an uptake test and I received radioactive iodine therapy to slow down my thyroid function. This threw me into a state of low thyroid function. Synthoid balances my thyroid function to normal and the negative symptoms disappeared.

Dosage & duration:   200 mcg (dosage frequency: 1 time per day) for the period of 10 years
Other conditions:   none
Other drugs taken:   none
  
Reported Results
Benefits:   The synthroid medication did, for most of the ten years while I took it, keep my thyroid levels where they were supposed to be.
Side effects:   After taking this synthroid medication for a period of about 10 years, here is what happened. We were on vacation in another state and all of a sudden I began to feel extremely horrible-- very weak, with a rapid heart beat. We were getting ready to get on an airplane and come home. So I thought if I can just get to my home town and get to a hospital, they can surely figure out what is wrong with me. We arrived at our home airport and then we went straight to the emergency room, where they ran several tests and I was there for several hours, but they could find nothing wrong with me. So they told me to go to my regular doctor the next day, which I did of course and he ran a blood test and found that it was the thyroid medication that was causing my problems.
Comments:   I was able to find an osteopathic doctor who put me on a natural thyroid, not a synthetic, he calld it a dessicated thyroid which came from an animal source, so I was able to get off the synthetic. Then after being on that for a while, he was able to get me off of that and I took a natural supplement, L- tyrosine It was wonderful to get off of a prescription medication. I hope this information may be helpful to someone out there.

Benefits:   Once I was diagnosed properly and began taking the synthroid, my dry skin cleared up, my energy level increased and my depression lifted. My hair is now thick and shiny again. I did not have weight gain so I cannot comment on that.

Comments:   I take one pill every morning with a very large glass of water. I must wait one hour before eating or drinking anything but water. I take this pill at the same time every morning and it took about 2 to 3 weeks to begin feeling better. I must get regular, every 3months, bloodwork to check thyroid levels.
