Ferric carboxymaltose for Iron Deficiency Anemia "Injectafer gave me my life back. I had been dragging myself along for five years and could not get better no matter how much iron I took or how much liver, beans, and spinach I ate. Every little task seemed exhausting, and I pulled back from life. About six weeks after Injectafer, all of my symptoms disappeared. It's not quick and easy. I'm on my third infusion, and about 12 to 24 hours after each treatment, I experience fatigue, body aches (deep in your bones), and a slight fever on and off for two or three days. I also feel spaced out and stupid. My hematologist recommended Claritin and Tylenol to help with the aches and fever. From last time I was treated, I know that feeling steamrolled and stupid will pass and that a renewed vitality lies ahead, so it's bearable. Schedule your infusions for Fridays so you can crash on the couch all weekend if you need to. I am so grateful for this medication. It rescued my quality of life."

Ferric carboxymaltose for Iron Deficiency Anemia "I've battled IDA (iron deficiency anemia) for 30 years due to heavy periods. My first iron infusion was with Ferrlecit in 2006, which worked well for me (no side effects), but was time-consuming; 8 infusions over 2 weeks (4 one week, 4 the next). Each infusion lasted about 3 hours from start to finish. Plus 8 IV start pokes. My first Injectafer was in 2015. I had it in 2017 & 2019 too. What a game changer! Only two infusions, spaced a week apart. I was at the infusion center about an hour both times! So much easier to schedule around work/children! Plus only 2 IV starts. I feel fatigued and anxious/sad for about 48 hours after the first infusion day, but it's not a deal breaker, & it goes away. I only have fatigue after the second week infusion, no anxiety/sadness (not sure why). No other side effects. My IDA symptoms begin improving 1-2 weeks after the second infusion. Overall, Injectafer is great & lasts me just as long (2 years) as the Ferrlecit & involves less time/pokes. Hope this helps!"

Ferric carboxymaltose for Iron Deficiency Anemia "My doctor called and told me I was overdosed on Injectafer. I don't know how it happened, but after the second dose, I passed out, and I have been dizzy, nauseous, completely drained of energy. Blurred vision since then. And I have to go for blood work twice a week for I don't know how long. It's been over a month now, and I still feel the same. It's just not getting better. I have been through many medical treatments and surgeries but have never felt this bad. I pray that the iron in my blood gets lower soon. Never again."

Ferric carboxymaltose for Iron Deficiency Anemia "Okay, so everyone reacts differently to medications, we all know that. However, in a lot of situations, you see more people leave reviews if they had a negative experience more often than if it was a good experience. Either way, if you’re on the fence about it, just try it! For me, it was so worth it and literally life-changing for me. My anemia was ridiculously low, the weight on my chest and feeling like I couldn’t breathe was nothing compared to the debilitating fatigue I was experiencing. Not to mention dry hair and nails, pale skin, and in a zombie state feeling bad every minute of every day! Tried oral supplements for 3 months, no improvement. My doctor finally sent me for this particular infusion, and I had two, 7 days apart. I was hopeless still even after the 2nd one, I felt no difference. But by week 4, I was so much better! Life-changing!"

For Iron Deficiency Anemia "I came here after searching the internet for a few symptoms after using this IV medication. I received 1 injection of 1,000 in total, and the week after I was in hard muscular pain, especially in my lower back, feeling depressive, anxious, sweating in my sleep, very fatigued, and with insomnia. It’s been a month, and the symptoms are decreasing, but not ended. My iron levels are higher, but not yet my HB. There is no info on this anywhere, and my doctor didn’t say any precautions before. It just now that I did the math on the date this started and the injection. It is 4 am, and I cannot sleep. After a month, the result is in my blood levels as with Venofer for me, the good part is 1 injection vs. 5, but with Venofer, it was just 2 days of fatigue, no pain, no insomnia or others after a month. I’ll be back to Venofer."
