Synthroid makes the heart beat faster?

Ok so I have a patient and she was recently put on a Synthroid and I noticed that her heart rate is faster than usual,also she takes another newly prescribed drug for better breathing Singular and lately her chest X-ray showed some abnormalities (nodules) When I saw her on my last visit I took a look at her morning VS (I go see her before lunch around 11-nish and in the morning her caregiver take her BP electronically and also does accu check and her pulse was 110 and diastolic BP over 100.When I did my own set of vital signs the BP was normal 120/80,and pulse was 95.She was asymptomatic.
Yes, Synthroid replaces the T3 and T4 not being produced by the thyroid gland. Speeds up everything, including HR and metabolism (although the later may be negligible) and may raise her BP. Synthroid dosing is kind of tricky, especially in the beginning, so she should be having levels drawn until she's within a therapeutic range. If her HR is consistently elevated, her dose may be too high. I'd definitely keep an eye on her labs. Hope this helps!

Best sources for information for this type of thing is:1. Nursing drug book2. MD3. PharmacistYou can even search for "Synthroid side effects" in google and you might find something there.I even did the work for you: Synthroid Side Effects | Drugs.com

Hmm ... well ... if you read the link, tachycardia and HTN are clearly listed. I'm not trying to sound like a jerk, but there are many people that don't use their resources.Thinking logistically you're giving what a thyroid gland is lacking. Using the good old critical thinking skill, if a patient is getting TOO much, you might expect s/s of hyperthyroidism. When going back to nursing classes, hyperthyroidism, depending on the severity, will cause tachycardia, hyperactivity, loss of weight, etc.

Synthroid raises HR, sometimes blood pressure...along with a host of other stuff. Tachycardia can be a symptom of excessive synthroid dosing...if your patient is newly starting on it, it bears watching. Some other things to watch for: hypertension, sleeplessness, palpitations, subjective feelings of being too hot, fatigue, excessive irritability...basically all the same symptoms as hyperthyroidism, since taking too much is like induced hyperthyroidism. And DEFINETLY make sure she keeps her lab draw appointments! She'll probably have them every 6 weeks or so until her labs are acceptable, then they'll drop down to every 6 months, then every year.

And, effects of Singulare added to the synthroid? Doesn't it also increase chance of tachycardia?

Shoot, I want to know too because I'm supposed to be taking Synthroid and have been putting it off! Not good for a future nurse, but I'm just so skeptical of taking some artificial substance for the rest of my days for some condition I don't even feel like I have. Apparently, the blood tests say otherwise. Argh!!!! I don't want to be borderline hypothyroidism and then turn around and be borderline hyperthyroidism. Que por favor??!!Eh, at least Kroger has it on the cheap generic plan.

I'm hypo and take a more natural compounded thyroid medicine, I've found doc's tend to just throw some Synthroid at you and don't do much follow up. I'm fortunate in that my doc is in a similar position as me, I also take bio-identical HRT's and thyroid so it's a real balancing act to get them all working right and to maintain.I can recommend:http://www.stopthethyroidmadness.com/http://forums.realthyroidhelp.com/index.phpI also belong to a Yahoo group called Coalition for Natural Desiccated Thyroid.Good luck!

I've been looking, but I can't find any information on how long it takes for hypothyroidism to take effect. Does anyone know? I possess none of the symptoms. When I feel tired, it could be debated that it's my iron deficiency anemia or just plain lack of enough sleep.The doctor discovered it by pure accident. They were drawing a whole bunch of blood to run some tests on an infected toe blister I had and ended up finding that. Don't ask me how they ran TSH for a toe blister. Anyway, they had me come in again for just a T3/T4 test and the results were the same and they sent me prescription in the mail. I have no idea what my levels are.

I have no experience with Synthroid, either personally or clinically. However, I was able to answer the question simply by using critical thinking. Synthroid is used for hypothyroidism = increases thyroid function = increases metabolic functions. Critical thinking skills are not something that we only have to use in nursing school. :-)
