For Vitamin/Mineral Supplementation and Deficiency "Day 3, I got extreme acid, bloat, gas, and what felt like heart palpitations. I stopped taking ferrous and still, 3 days later after stopping, I still had symptoms. No over-the-counter meds helped, I ended up going to the hospital due to the severity."

For Iron Deficiency Anemia "I've only been taking this for about 3 days, and it's been a 3-day pure gastrointestinal nightmare. Stomach ache, bloating, nausea, and the gas! The gas is out of control, and I'm surprised my family still wants to be around me. I am definitely gonna switch to a non-sulfate version."

For Iron Deficiency Anemia "I've been taking ferrous sulfate for 2 weeks now, and I do notice I have more energy. I still get pretty tired early in the night, but when I wake up, I am no longer exhausted. I suffer from GI issues that can easily be triggered if the wrong thing goes into my stomach. I was very skeptical about iron pills, but my doctor told me to take the pills with breakfast. I feel this has helped me not suffer terrible GI issues. If I eat dinner at 6/7 pm and breakfast at 9 am with no lunch or snacks in between, I have noticed that I get really nauseous about an hour after dinner. Although, if I eat more frequently throughout the day, I am completely fine. There have been a couple of days where I didn't pass a bowel movement, but I did not feel like I had to. Typically, it's normal for me to go once a day. I feel I will sometimes experience very mild constipation on this pill. I take a probiotic every single day with the pill to make sure I am as regular as possible."

For Iron Deficiency Anemia "Okay, so today when I woke up, I had diarrhea, and it made me feel very weak. I lost energy because of taking ferrous sulfate, I think. I pooped dark and watery, and it is really the worst thing ever. I just want to ask, should I still continue the ferrous sulfate? By the way, it'll be four weeks in two days, and I felt better but still pale. But now I have diarrhea. What do I do?"

For Iron Deficiency Anemia "I began to have more energy after about two weeks of taking the iron and vitamin C. Then I began to notice my blood pressure was steadily increasing. Instead of being slightly elevated in the morning and dropping by mid-morning, it was higher levels each morning and staying high all day unless the blood pressure was treated. My doctor and pharmacist say they haven’t heard of this as a side effect. Today was my second morning without the pill, and my systolic pressure has dropped 5 points."

For Iron Deficiency Anemia "Do they have lactose in them? Third day taking them and felt so sick I checked the ingredients-they contain lactose. Iron deficiency is a direct cause of lactose intolerance, and it's reported that 70% of us are intolerant anyway. I don't know why they put that in them! Ask for a lactose-free prescription."

Ferrous sulfate for Vitamin/Mineral Supplementation and Deficiency "It is supplied in non-blister packaging by some manufacturers. Be specific about what you need if you have difficulty with the individual packaging. Pharmacy staff have been able to help me. I have been taking it regularly for over 10 years, and it has kept my blood levels up."

For Iron Deficiency Anemia "The drug makes me severely sick to the stomach with bad stomach pains and frequent loose stools. I have also been having headaches, but I am not 100% sure that it is related. I have taken it off and on for years and never had side effects. Perhaps I need to take it with food or not when I take my other meds."

Ferrous sulfate for Iron Deficiency Anemia "Please pay attention to the comments about the packaging. Always have to look for something-a knife, tine of a fork, etc., etc., to get the stupid pill out-and then hope it doesn't burst out and careen onto the floor."

For Iron Deficiency Anemia "Needed for low iron levels. Reduced my period bleeding, extreme bloating, and some nausea. Even tried taking it with a meal and lots of citrus for vitamin C. Makes stool darker and smellier, I eat lots of vegetables for my normal diet, so no constipation was experienced. Stopped after around a week."

For Iron Deficiency Anemia "Dr. prescribed iron, and I was feeling better at two weeks. Take 3 months, then follow up at 3 months. Only told to watch for constipation. 2 months later, suddenly began having diarrhea with a sudden urge to go… now. This went on for almost a month, thinking it had something to do with the new hypothyroid med. but honestly, it all began about 4 days before I began this med. I was convinced it was to do with something thyroid-related, as the only other thing I was taking was iron, and everybody knows iron makes iron stool, and the doctor told me only of constipation too… this was not the case. I was waiting for a follow-up with the endocrinologist (thyroid doc) to see what she thought, which was scheduled before my regular doc follow-up for iron. She was as confused as me. Between taking iron that supposedly only will back you up and hypothyroid, which also slows that down."

For Iron Deficiency Anemia "Took this for anemia due to menorrhagia. Caused severe abdominal pain, bad taste in my mouth, slight nausea. My doctor was confused and ready to refer me to a gastroenterologist. I got some relief from the abdominal pain with taking low dose OTC iron instead. All these issues stopped when I had a hysterectomy and no longer needed iron."

For Vitamin/Mineral Supplementation and Deficiency "I get cramps from racing motocross. We call it 'arm pump.' I take only one a day for 3 days before the race and get no arm pump. I now have about 15-20 people using it. It's hard to find sometimes."
