If you’ve recently been diagnosed with hypothyroidism (an underactive thyroid gland), your doctor may want to prescribe you Synthroid. If you haven’t taken this medication before, you may have lots of questions. Here is some basic information about Synthroid along with reviews from actual users to help you decide whether or not you should take Synthroid.
What is Synthroid?
Synthroid is the brand name for levothyroxine, a synthetic thyroid hormone for people who don’t produce enough thyroid hormone. Synthroid should ONLY be taken by people with low levels of thyroid hormone. People with normal thryoid levels can suffer life-threatening side effects. Synthroid is not intended to help people with normal thyroid function lose weight.
Synthroid Side Effects
Like any medication, Synthroid may cause side effects. Some side effects you may experience include:
- Changes to your menstrual cycle
- Chest pain
- Excessive sweating
- Increased appetite
- Rapid or irregular heartbeat or pulse
- Sensitivity to heat
- Stomach cramps
- Temporary hair loss
- Weight loss
You should not take Synthroid if you have normal thyroid levels; it isn’t intended for weight loss. Synthroid may also lead to osteoporosis, especially in women.
Before taking Synthroid, you should tell your doctor if you have ever had:
- Blood-clotting disorders
- Chest pain
- Heart attack
- Heart disease
- High blood pressure
- Irregular heartbeat
- Kidney disease
- Underactive adrenal or pituitary gland
Also be sure to tell your doctor about any medications you take, especially any of the following:
- Antidepressants or drugs for anxiety
- Anti-seizure medications like phenytoin (Dilantin)
- Blood thinners such as warfarin (Coumadin)
- Diabetes medications, including insulin
- Estrogens and oral contraceptives
- Heart medications, such as metoprolol (Lopressor, Toprol), propranolol (Inderal), and digoxin (Lanoxin)
1/21/19 - "To be honest I'm not a person who has ever taken medications. So when my physician told me I had a under active thyroid I didn't really know what to think because I didn't feel as though I had any of the common symptoms. I just thought the symptoms the doctor mentioned were just normal ageing since I am 55 years old. I have been taking this medication now for a little over 4 months and have started to see some noticeable changes. 1) my hair stopped falling out. 2) nails started growing faster and stronger. 3) All around much more energy. 4) Able to focus better. So far I have been very happy with the results. I cannot give this a total 10 because everything has room for improvement."
12/16/18 - "Since the FDA changed the pills several years ago from the prior I have been struggling with weight and my potassium and magneseum levels off and on. In 2008 I was 150-165 lbs today I am about 205 lbs. I have NO thyroid so its a true struggle, that is barely understood. Pray for a better product!!!!"
10/11/18 - "I started taking 100mcg 14 years ago at 24 after I had my first child, at first it did help with minimal side effects but after the birth of my second child 3 years ago I had to raise the dose to 112mcg and I am always dizzy always have headaches. I have extremely bad anxiety. It does regulate your thyroid but I really dislike all the side effects."
10/1/18 - "I've been taking generic (levothyroxine) for 2.5 years. I took for a little while about 4 years but I didn't keep up with my health as I should have. My TSH was 58.8 and I started on 50 mcg. After seeing my GP and now an Endocrinologist, I am now up to 150 mcg and the last TSH was .99 I have had no side effects from either Synthroid or the generic. The medicine does what it's supposed to do. My hair grew back, the fog lifted, got my energy back, severe muscle pain went away, joints no longer hurt and my cholesterol went down from 280 to 200. I take it in the morning but don't follow any rules. The endo just said to take it. I usually take it with my Vitamin D, prescription pepcid, and Vitamin C. I take it with coffee or milk. The endo said it really didn't matter, just take it because not taking it is not an option."
8/21/18 - "I have been on Synthroid for 12 years and I have had no side effects. I only have good things to say about this drug. However, when you start blood tests are essential to determine the right dosage. You must take on an empty stomach and no food for about an hour. Also, you need to keep the Synthroid level constant in your blood system. If you skip a day or two It is like you have to start over to get back to the dosage you were prescribed. This drug works. Use it as your Dr. tells you to and have blood tests on a regular basis."
8/1/18 - "I was recently diagnosed with slightly sluggish thyroid and put on 50mg Levo ( Thyrax duo tab). My already anxiety condition got worse. After a few weeks my vision became blurred just thought it was my eyes getting old im 54. Two weeks on I collapsed at work from exhaustion. Breathless and weak. Doctor did complete blood anylse everything normal. I told him maybe the Levo, he said no way. I was in a bad state. Back to doctor. Sent me for lung photo. Showed nothing. He went on holiday for 3 weeks without telling me and the stand in cannot get into my records and told me she cannot give me any refferal and my bloods are fine and wont even give me an appointment. I now have full blown asthma and hay fever symptoms and have to wait 2 more weeks before my doctor is back to try to change the meds."
