What should I avoid taking alongside my synthroid?

What should I avoid taking alongside my synthroid?

Potentially: hundreds of other meds might interact in some way with Synthroid. Your doctor can run an interaction check between Synthroid & your other Rx's. In general, however, if you take Synthroid 2 hours after and 1/2 hour before meals, other meds, mineral & fiber supplements and antacids, you will avoid most interactions with Synthroid. Best wishes!

I just seen my synthroid expired 13 months ago. I have been useing it for sometime now. Will it still be effective I wonder or make me ill?

I just seen my synthroid expired 13 months ago. I have been useing it for sometime now. Will it still be effective I wonder or make me ill?

It will not be 100%: effective. Most prescription expiration dates are estimated to be two years from when it's manufactured. So if your Synthroid expired in March 2016, meaning it was manufactured in 2014. So in 2017, it may be only 50% effective. Since it's important to know if your synthroid is effectively treating your hypothyroidism, it's best to use Synthroid that's in date. ...Read more

Each morning before I take my synthroid I feel very bad and about 1 hr after taking it feel good. Why is that? Does it wear off by the morning?

Possibly,..: Everyone metabolizes medications differently, and in your case, your symptoms are what they are, so it is possible the meds are waxing in the AM. Try talking to your Dr. and maybe taking the meds at Noon or even in the PM hours may help decrease the feeling you get in the AM. Best wishes. ...Read more

Is generic (levothyroxine) instead of Synthroid not as good?

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 more

Can the generic for Synthroid (levothyroxine) be broken into 4? I take half one day and a half of a half the next.

Can the generic for Synthroid (levothyroxine) be broken into 4? I take half one day and a half of a half the next.

Break into four: Sure it will work but probably not as well as half a tablet each day. Don't forget to have your doctor check your thyroid levels every 3-4 months till it is sure that your levels are stable. ...Read more

Does generic of Synthroid (levothyroxine) disperse the dosage equally throughout pill. I'm on 75mcg so if i cut in half will i get 37.5mcg?

It's not the: Cutting in half that's a problem, as even if the cut is uneven it won't matter since the half-life of T4 is 7 days and the doses will overlap. The problem is that the generics aren't as reliable and the dose and potency will vary every time you get a new prescription, or the pharmacy changes suppliers, or with age and storage of the rx, etc. It is better and safer to stick w/brand name t4. ...Read more

Is there a difference between levothyroxine and synthroid? I was told to take name brand because it's better. I thought it was the same thing.

Synthroid (thyroxine) better: Synthroid is a brand name t4, levothyroxine is the name of the generic. Many studies have indicated the brand name is more reliable and consistent. However, your insurance company will probably want you to take the generic because it's cheaper. A yugo is cheaper than a cadillac, but they are both cars -- so they're the same thing -- right? ...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 more

No. : No. You should be ok. Side effects of too much thyroid include: rapid heartrate, chest pain, fatigue, sweating. It should be temporary. You really need to make sure that you don't do this again. I suggest using a 7 day pill box to help remind you whether you took the medicine already or not. Best wishes. ...Read more
