Iron Injections..any had these?

My PCP is setting me up with a specialist to have an iron injection and I am curious what to expect??.  any advice from those that have had these.  I am pretty excited as it will be nice to not be so tired, so dizzy, hair loss, dry skin...and all the other crud we deal with.  It has all been worth it but at 2 yrs post op I can't get my iron levels up.  Just when I think it is moving in the right direction I drop to the lowest I have ever been..sigh.

Do you mean iron infusions?  I've never heard of iron injections.

I am currently getting iron infusions.  Last year I got 4 days in a row in one week. But this year they changed a protocol and I am getting one infusion a week for 4 weeks. 

This year - I can feel more side effects from it. Last year I was so tired and they were all together - this year... I have done 2 and 2 more to go. 

Some people get side effects - others not so much.  The side effects may be different for different iron they use. 
I am getting iron-sucrose, and what I hear - that is the best tolerated iron by most people. 
The side effects are 2 types. The iron - and the side effects of drugs they give so you don't get allergic reaction. (like IV benadryl, IV steroids and IV antacid). The whole process took app 3- 3.5  hrs.
The IV drugs - the benadryl knocked me out and I was groggy that whole day. I could function, but it made me tired.  The the next day I got the steroids high... a lot of energy, could not sleep much.... that lasted for 2 days.  Then came the after steroids low - one day I felt down and really tired.. (but you have that every day now - so ...)  That lasted for 2 days... and I slowly started getting up ... and I had second infusion.  Great.  The cycle started again.  Being aware what and why I feel the way I do - I could plan accordingly and even warn BF and coworkers.  

Then the iron itself side effects - abdominal - even though I got the iron IV - but the antacid and the iron caused some indigestion and cramping.   I had the iron on Tuesday and today is my "acid burns me" day, even though I am taking additional antacid and I try to take it easy.  
The acid may be due to the iron the body dumps into the digestive track - the extra that will not keep - or a rebound effect from the IV antacid.   But as long as you know it - and are prepared for that - (if may not happen to you) you can handle that. 

For our body to be able to utilize the iron we need to a make sure our proteins level are good (iron binds to protein in ferritin) - so make sure you have that covered.  
Also - really important - make sure they check your copper and B12 and folic acid. Insist on that.  If you copper is low - even if they give you iron -  you body may not be able to make new good blood cells. Same applies to B12, and other minerals. 

Maybe be good idea  if you don't get that - to ask for one B12 shot - unless you know your levels are very good. (>800).

There are iron injections available.  Not sure how they will work for us, I did have a WLS friend that had them (one weekly) for a month prior to her plastics and it did work for her.

I've had iron infusions which did a world of good on how I felt.  Although I'm not officially anemic I'm contacting my PCP to try to get them again, my ferritin dropping significantly since last year.  Looks like infusions may be a part of my life now.

Like H.B., I had ferrous sucrose infusions for awhile. My ferritin was a 2 before I started and my doctor had no clue how I was still functioning daily. The drug name was Venofer and it was pretty tolerable. I was loaded on benadryl for them since I'd had an anaphylactic reaction to ferrous gluconate. They took about an hour or two out of my day once a month for 1.5 years.

I was able to go to work afterward (albeit groggily), but I take the subway and didn't need to drive. I would definitely not have been a safe driver on the IV benadryl.

I'd usually feel sore and have a little bit of joint pain for a day afterward, but after a few infusions I had so much more energy I didn't care! Good luck to you.
