Levothroid Vs Generic
Is generic levothyroxin as effective as brand name Synthroid (thyroxine) for treating hypothyroidism?
NO!: You only want to use brand name T4 replacement. There are several brand names available, but don't switch back and forth from one to another as even subtle differences in potency can cause big changes in your thyroid level. Don't take generics, as they're cheap but unreliable. ...Read more
Are the brand name "synthroid" &levothyroxine equally effective? M taking synthroid. Can I switch 2 levothyroxine, looks like levothyroxine is cheaper
Levothyroxine is: cheaper since it's a generic, but the blood levels with Synthroid (thyroxine) are more consistent and reliable. It is a product with a "narrow therapeutic window" where generics can vary from batch to batch, company to company and prescription to prescription -- while the brand name product does not. If you can afford it, take the brand name drug. ...Read moreSee 1 more doctor answer
Generic: Not much difference. Both work well.Get a more detailed answer ›
Yes: The fda allows for a 5% variance in brand name medications but a larger variance in generic "equivalents." synthroid and levothyroxine are not considered equivalents and thus not interchangeable. Therefore, stick with one; if you have started on synthroid stay with it, if you have started on levothyroxine stay with it. ...Read moreSee 1 more doctor answer
The price!: With very rare exceptions, the vast majority of generic drugs are every bit as good as the brand name. However, the brand name usually costs a whole lot more! the active medicine should be identical but there may be differences in the fillers and binders (most drugs have many ingredients besides the active medicine). Some people may tolerate one more than another due to these minor differences. ...Read moreSee 2 more doctor answers
Yes: Generic synthroid is called levothyroxine. Taking generic version is reasonable and will likely achivevsimilar results , however i would recommend that you inform your endocrinologist about such switch as you may need to have your thyroid levels checked soon (a few weeks) after making the switch to ensure your dosing is appropriate. I would also recommend that you adhere to one kind of preparation. ...Read moreSee 1 more doctor answer
Consistency of med: There is no problem with generic thyroid as long as you have some underlying thyroid function. If you have no thyroid function (i.e. After total thyroidectomy), your thyroid level will fluctuate if you get different brands of thyroid or generics from different companies. The advantage of taking a particular brand is that the amount of medicine is consistent so thyroid levels will not fluctuate. ...Read moreSee 1 more doctor answer
I'm currently taking buproprian (generic for wellbeautrin) is there a big difference between brand name mental health drugs and generic?
In some, yes: By law in the us, all generics are supposed to contain equivalent amounts of active ingredient -- but they sometimes don't. There have been problems with generic bupropion, in some cases. Also different companies use different fillers and dyes in their products -- which can result in differing effects in patients also. Please talk with your doctor & the pharmacist who dispenses your medication. ...Read moreSee 1 more doctor answer
Yes: All generics are equivalent to their brand name counterparts. The active chemical is exactly the same. Some people may react to some additives or fillers used in manufacturing the medicines - brand name or generic, but the medicine itself, it's efficacy, and safety are no different. Provided you get a legitimate medicine that has been authorized by the fda. ...Read more
Should I take named brand thyroid medicine like Synthroid (thyroxine) or generics? I heard name brand dosing is more consistent. Your thoughts?
Thyroid meds: Thyroid medication is one of the most common medications written for. I use generics unless there continues to be a wide variability in the labs (TSH) that are used to follow this condition. Cerainly if the patient desires a branded name i usually comply. ...Read more
No: Hi. No, they're completely unrelated. Thyrocalcitonin (usu. just called calcitonin) is made by thyroid C cells (which do NOT make thyroid hormone) and is used as a tumor marker for medullary thyroid cancer (e.g., MEN-2 syndromes). T3 (liothyronine) is the active form of thyroid hormone that the body makes from T4. ...Read more
Cost: To meet fda rules, all active ingredients in generic medications must be identical to active ingredients in brand-name meds. Generics, however, may use different 'inactive' ingredients: different dyes, binding agents, etc. Since the inactive ingredients 'do nothing, ' the meds are equivalent.The only difference, in theory, is some patients may be allergic to some inactive ingredients & not others. ...Read more
Stick with one: Thyroxine sodium and levothyroxine are simply different forms of generic "synthroid". Neither is better than the other. Whichever form you take, stick with it. The bioavailability of each thyroid preparation is a little different. If you switch from one form to another, your thyroid numbers may change, and you may start to feel hypo or hyper. Sometimes pharmacists switch you to save $. ...Read more
