Taking Synthroid (thyroxine) 125 and felt a sudden adrenaline rush on my heart. Should I be worried?
Been on armour for two months was on synthyroid for 20 yrs, feeling better but certain days I feel like I'm on an adrenaline rush, heart rate 95bpm?
Thyroid replacement: This is why most endocrinologists don't use armour. It contains a mixture of hormones, and often does makes you hyperthyroid. And it is hard to follow the blood tests. ...Read more

Depends.: Levoxyl (thyroxine) does not cause irritation to the stomach. But it depends on what you took it with and how soon after taking it, unless it was with a small sip of water. It is always best to wait 45 minutes to 1 hour before lying down after significant water intact, or eating. ...Read more
The dentist may use anesthetic such as 0.3ml lidocaine with 1:100, 000 epinephrine. Would this interact/ have problems with my heart or BP medication.
Stress form the procedure, particularly if you were not numb, would cause your body to release more Epinephrine then what is in the local anesthetic.
That said I do try to error on the side of caution depending on the heart condition by not using the maximum dose (approximately 8 full injections) and breaking up multiple procedures over several appointments. ...Read more

If a person is having anaphylactic shock, their blood vessels may suddenly dilate.

What would be the problem causing chest pain and irregular heart beat while taking synthroid (thyroxine)? Can it cause mi?
See Below: Any chest pain needs to be investigated by a physician to rule out cardiac origin. Synthroid (thyroxine) may cause tachycardia or irregular heart beats if the dose of the medication is higher that what the patient needs. That is why thyroid functions tests need to be done while on Synthroid (thyroxine) to make sure that the dose is adequate. ...Read more

What does gait weakness mean? Also, any idea what would cause elevated epinephrine levels and heart rates that race multiple times a night and races at the slightest movement?
Pheochromocytoma: A pheochromocytoma is a growth in the area of the adrenal glands that causes hypertension, elevated catecholamine levels and palpitations. It is not a common condition and an endocrinologist is best qualified to evaluate for one and I recommend that you consult one in view of your symptoms. He/she will order the appropriate tests and refer you to a cardiologist if it is deemed advisable. ...Read more
How high does epinephrine have to be to be considered a pheochromocytoma? Also, I have attacks multiple times a night (every night) with heart rates as high as 174bpm. Used to have episodes of nausea,
This question is: Really complex, and I am concerned that an answer may only make things more confusing if it is too specific. I think in situations like this a thorough history and physical by an internal medicine doctor and possibly a second opinion would be a great way to shed light on something that seems foggy. Pheochromocytoma is truly rare. There are common things that should be looked into first. Best 2 U. ...Read more

I forgot my Synthroid (thyroxine) for three days could that cause me to have rapid heart rate at 3 am? I take 112 mcg 6 days a wk. No thy gland. Almost went to ER
If I was not compliant with taking Synthroid (thyroxine) will heart pills like amiodarone make me feel worst?
Yes: In general, not taking medications that were prescribed to you in the way they were prescribed is not healthy. Sometimes this will not make you feel bad (cholesterol medicine, eg), but other times like with levothyroxine (synthroid), this will leave you hypothyroid, which can make you feel tired, constipated, cold, depressed, etc. This is irrespective of whether you were compliant with amio or not. ...Read more

Your dose suggests that you have mild to moderate low thyroid. Without your medication you could expect weight gain, hair loss, constipation, depression, feeling cold, and feeling lethargic. In cases of severely low thyroid, coma and heart damage can occur.

What does ER do if a patient with heart disease and tachycardia has anaphylaxis shock? Do they still give epinephrine injection?
Usualloy yes.: Tachycardia is frequently caused by anaphylaxis. The only drug that truly treats the condition is epinephrine. Therefore, the drug should still be used in patients with heart disease. However, a good way of reducing the danger from the medication is to give lower initial doses, e.g. A pediatric dose of 0.15mg im, which can be repeated every 10 minutes as necessary. ...Read more
Can't use epinephrine I get rapid heart rate, endodontist wants to give me 20 mg Valium crushed 1/2 hour before root canal. Is this ok?
Epinephrine: After over 40 years of dental practice I have had only a handful of patients who truly are sensitive to Epinephrine in local anesthetics. Almost all patient who say they react with an increased heart rate do so because of the release of their own epi due to anxiety, or react from poor injection technique. Ask your dentist about the use of sweet air instead of valium. Btw ok with precautions. ...Read more

Started Synthroid (thyroxine) 7/18, TSH was 9.19 retest 9/26 TSH 11.25 after starting Synthroid (thyroxine) breathing difficulties & rapid heart, doc wants to up synth to 88?
Thyroid problem: You may be having more than a thyroid problem, e.g. Female hormone imbalance or other. Ask for complete hormone testing and also more thyroid tests e.g. Free t4, free t3. You may not be converting the synthroid (thyroxine) which is T4 to the biologically active t3. Probably should ask for consultation with specialist e.g. Endocrinologist. ...Read more

My TSH levels are at a 4.25. I am currently taking 50mcg of synthroid (thyroxine). My doctor upped my dose to 75mcg. I am afraid of side effects like racing heart?
Take it: Adjusting a thyroid medicine is both an art and science. You need to be "euthryroid" meaning normal tsh, t3, (liothyronine) T4 and must feel well as the normal range is made for a population and not your particular body. Fine adjustments must be made between you and a trusted doctor with an aim to make you feel well and healthier and avoid side effects such as palpitations. So go slow. ...Read more
Can hypothyroid symptoms be fast heart rate and insomnia? Will adding cytomel to Synthroid (thyroxine) help?
Maybe hyperthyroid: Hyperthyroidism (too much circulating thyroid hormone) will often produce rapid heart rate and insomnia - along with other symptoms like diarrhea, weight loss, and jitteriness. Low thyroid may cause weight gain, sluggishness, coarse/dry skin, and constipation. Ask your care provider about your symptoms. Please do not "freelance" with Cytomel or synthroid, (thyroxine) as this may harm you! Lgromko md. ...Read more
