Pharmacist tips for FeRiva 21/7
- Make sure to tell your provider and pharmacist about all the medications you're taking before starting an iron multivitamin. Certain medications, such as antacids (e.g., calcium carbonate (Tums)), tetracyclines, and fluoroquinolones, interact with the iron in FeRiva 21/7. Don't start any new medications while taking an iron multivitamin without talking to your provider or pharmacist first.
- Check the labels of any other vitamins (including multivitamins) and supplements you're taking. Don't take additional iron or multivtamins than what's prescribed by your provider. Doing so can lead to side effects from too much iron, such as upset stomach, nausea, and constipation.
- Make sure to have a healthy and balanced diet high that contains iron while taking FeRiva 21/7. Depending on your iron levels and why you're taking an iron multivitamin, it's possible you might be able to stop taking the iron multivitamin if your nutrient levels are enough with diet alone.
- FeRiva 21/7 can cause your stool to be discolored, which is a common side effect of iron supplements. Don't be alarmed if you see your stool turn a black color from this supplement.
- Keep FeRiva 21/7 out of reach of children so that they don't accidentally take it. If your child took FeRiva 21/7 and you notice them vomiting up blood or having diarrhea and stomach pain, call your local Poison Control Center right away at 1-800-222-1222.
Risks and warnings for FeRiva 21/7
FeRiva 21/7 can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Iron overdose
- Risk factors: Taking too much iron | Receiving multiple blood transfusions | Medical problems that raise your blood iron level | Children under 6 years of age
If you take multiple supplements that contain iron or take more FeRiva 21/7 than recommended, there's a chance that your iron level will become too high. This is dangerous because it can lead to problems such as tears in the gut, seizures, and liver damage. Your provider will regularly do blood tests to check your iron level while you're taking FeRiva 21/7. Let your provider know immediately if you experience symptoms of too much iron, such as nausea, vomiting, stomach pain, and diarrhea.
Accidental overdose of iron-containing products, like FeRiva 21/7, can be extremely harmful to children under 6 years of age. Keep FeRiva 21/7 out of reach of children so that they don't accidentally take it. If your child took FeRiva 21/7 and you notice them vomiting up blood or having diarrhea and stomach pain, call your local Poison Control Center right away at 1-800-222-1222.
Masking anemia due to low vitamin B12
FeRiva 21/7 contains folic acid. If you have a low red blood cell (RBC) count that's related to having low vitamin B12 levels (pernicious anemia), then taking folic acid might hide your condition. This is because your lab results for your RBC count might show it's within normal range, even though you still have anemia. This means that you might not get the medical attention you need. If you have a history of low vitamin B12 levels, let your healthcare provider know.
