Pharmacist tips for FeRiva 21/7

pharmacist

  • 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.

        • 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.

          faqs

          Frequently asked questions about FeRiva 21/7

          What does the "21/7" mean in "FeRiva 21/7"?
          FeRiva 21/7 comes as a 28-day blister pack that has 21 red active medication tablets and 7 purple placebo (sugar pill) tablets. You'll need to take 1 red tablet by mouth once daily for 21 days, followed by 1 purple tablet by mouth once per day for 7 days. After you finish the 28-day blister pack, your provider will decide if you need to take another blister pack of FeRiva 21/7 or not.
          What are the 7 purple placebo tablets that come with the 28-day blister pack for?
          The 7 purple placebo tablets don't have any vitamins or supplements in them. The manufacturer claims that the purpose of the 7-day, iron-free period is to prevent iron build-up in your stomach and intestines. Taking placebo tablets can help keep you in the habit of remembering to take a pill once daily. This will help you to not miss any doses of pills with active medication if you're taking additional packs.
          How is FeRiva 21/7 different from other iron supplements?
          FeRiva 21/7 differs from some other iron supplements in that it contains additional vitamins and supplements besides iron. Also, the iron in FeRiva 21/7 is in the form of ferrous asparto glycinate, whereas the iron in most iron supplements is in forms such as ferrous sulfate or ferrous gluconate. The manufacturer claims that these factors help you absorb iron more easily into your body. Finally, FeRiva 21/7 can be taken with or without food whereas most other iron supplements need to be taken without food to help with absorption of iron into the body. Ask your provider if you're not sure which iron supplement are good options for you.
          Can I take FeRiva 21/7 if I'm pregnant?
          Ask your provider whether FeRiva 21/7 is the right multivitamin for you to take during pregnancy. FeRiva 21/7 contains vitamins and minerals that are important in pregnancy, such as iron and folic acid. For example, iron (and folic acid) helps prevent and treat anemia for both mother and baby. And folic acid is key in helping your baby's brain and spinal cord develop properly. But before starting FeRiva 21/7, ask your provider to see if the ingredients in this multivitamin and their dosages are appropriate for your needs.

          What are the 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.

          risk-warning

          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.

            risk-warning

            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.
