Fosrenol contains the active ingredient lanthanum carbonate. It is a prescription medication used to help lower high phosphate levels in people with advanced chronic kidney disease, especially those receiving dialysis.

It does not treat kidney disease itself. Instead, it helps control one of the mineral problems that can develop when the kidneys can no longer remove enough phosphate from the blood.

What is Hyperphosphatemia?

Hyperphosphatemia means that the amount of phosphate in the blood is too high.

Phosphate is a mineral found naturally in many foods. Your body needs some phosphate for healthy bones, cells, and energy production, but too much can become harmful.

Healthy kidneys normally remove extra phosphate through the urine. When kidney function becomes severely reduced, phosphate can begin to build up in the bloodstream.

Why High Phosphate Levels Can Be a Problem

High phosphate levels can upset the balance between phosphate, calcium, and other minerals in the body.

Over time, this imbalance may contribute to weakened bones and abnormal mineral deposits in blood vessels or other tissues.

For people with advanced kidney disease, keeping phosphate under control is an important part of long-term treatment.

Why People on Dialysis May Need Fosrenol

Dialysis removes many waste products from the blood, but it may not remove enough phosphate to keep levels within the desired range.

Because of this, some people need additional treatment with a phosphate binder such as Fosrenol.

Fosrenol is generally used together with dialysis, dietary phosphate control, and regular blood testing.

How Fosrenol Works

Fosrenol belongs to a group of medicines called phosphate binders.

It works inside the stomach and intestines rather than relying on the kidneys to remove phosphate.

How Fosrenol Binds to Phosphate

When you eat, phosphate from food enters the digestive tract.

Fosrenol binds to this dietary phosphate and forms a compound that is difficult for the body to absorb.

As a result, less phosphate enters the bloodstream.

What Happens to the Bound Phosphate?

After Fosrenol binds to phosphate, the bound material passes through the digestive system.

It is then removed from the body through the stool instead of being absorbed into the blood.

This helps lower the amount of phosphate that reaches the bloodstream after meals.

Why Fosrenol is Taken With Food

Fosrenol works best when it is taken with or immediately after meals.

This timing is important because the medication needs to be present in the digestive tract while phosphate from food is being released.

Taking it away from meals may make it less effective.

How Fosrenol Fits Into Kidney Disease Treatment

Fosrenol is usually only one part of a broader treatment plan.

Your healthcare provider may also recommend a phosphate-controlled diet, dialysis, and other medicines to help manage mineral balance.

These treatments work together to reduce the complications that can occur when phosphate remains too high.

Foods Can Affect Phosphate Levels

Many foods contain phosphate, including dairy products, processed meats, cola beverages, some packaged foods, and foods containing phosphate additives.

Your kidney care team or dietitian may recommend limiting certain high-phosphate foods while making sure you still get enough nutrition.

Fosrenol does not replace dietary recommendations. It helps reduce how much phosphate your body absorbs from the food you eat.

Monitoring During Treatment

Your healthcare provider will usually check your blood phosphate levels regularly while you are taking Fosrenol.

Other blood tests, including calcium and related mineral levels, may also be monitored.

These results help your healthcare provider decide whether your dose should be adjusted.

Dose Adjustments

The dose of Fosrenol is individualized.

Your healthcare provider may increase or decrease the amount you take depending on your phosphate levels and how well you tolerate the medication.

Do not change your dose on your own.

Fosrenol Does Not Cure Chronic Kidney Disease

Fosrenol does not restore normal kidney function and does not cure end-stage kidney disease.

Its role is to help control excess phosphate and reduce the problems associated with long-term phosphate buildup.

Why Consistent Use Matters

Phosphate levels can rise again if the medication is not taken as prescribed.

For the best results, take Fosrenol with meals, follow your recommended diet, attend dialysis as scheduled, and complete your regular blood tests.

Consistent treatment helps your healthcare team keep your phosphate levels within the recommended range and manage your kidney disease more effectively.

Fosrenol is available as chewable tablets in several strengths, including 250 mg, 500 mg, 750 mg, and 1,000 mg.

It is used to lower high phosphate levels in people with advanced kidney disease. Because Fosrenol works by binding to phosphate from food, it should be taken with or immediately after meals.

Chew the Tablet Completely

Fosrenol chewable tablets should be chewed thoroughly before swallowing.

Do not swallow the tablets whole. Swallowing an intact tablet may increase the risk of digestive blockage or other complications, especially if you have difficulty chewing or poor dental health.

If chewing is difficult, the tablet may be crushed completely before taking it, according to your healthcare provider’s instructions.

Why It Should Be Taken With Meals

Fosrenol works inside the digestive tract by attaching to phosphate from the food you eat.

Taking the medication with or immediately after a meal allows it to bind to phosphate before that phosphate can be absorbed into your bloodstream.

Taking Fosrenol away from meals may reduce how effectively it controls your phosphate level.

Starting Dose

A common recommended starting amount is a total of 1,500 mg per day.

This total daily amount is usually divided among meals. Your healthcare provider may tell you to take different amounts with different meals depending on your phosphate levels, eating habits, and treatment needs.

How the Daily Dose May Be Divided

For example, if your total daily dose is 1,500 mg, your healthcare provider may divide that amount between breakfast, lunch, and dinner.

The exact amount taken with each meal can vary. Do not divide or adjust your dose unless your healthcare provider tells you to do so.

Dose Adjustments

Fosrenol dosing is individualized according to your serum phosphate level, which is measured through blood tests.

Your healthcare provider may adjust your dose every 2 to 3 weeks until your phosphate level reaches the desired range.

Dose changes are usually made gradually so your response can be monitored safely.

Usual Daily Dose Range

Many patients need a total daily dose between 1,500 mg and 3,000 mg to achieve adequate phosphate control.

Some people may require more or less depending on their diet, dialysis treatment, phosphate levels, and response to the medication.

Clinical studies in people with end-stage renal disease have evaluated total daily doses of up to 4,500 mg.

Do Not Increase the Dose on Your Own

Do not take extra Fosrenol because you have eaten a high-phosphate meal unless your healthcare provider has specifically instructed you to adjust your dose this way.

Taking more than prescribed may increase the risk of side effects without providing additional benefit.

Regular Blood Tests Are Important

Your healthcare provider will check your serum phosphate level during treatment.

Testing may be more frequent when you first start Fosrenol or when your dose is being adjusted.

Once your phosphate level becomes stable, your healthcare provider will continue checking it periodically to make sure treatment remains effective.

Why Your Dose May Change Over Time

Your phosphate level can change because of several factors, including:

  • Changes in your diet
  • Changes in dialysis
  • Missed doses
  • Changes in your overall health
  • The amount of phosphate in the foods you regularly eat

Because of this, the dose that works well at one point may need to be adjusted later.

Take Each Dose Consistently

Take Fosrenol with each meal or snack for which it has been prescribed.

Skipping doses may allow more phosphate from food to enter your bloodstream, making it harder to keep your phosphate level controlled.

If You Miss a Dose

If you forget to take Fosrenol with a meal, do not usually take the missed dose later when you are no longer eating.

Because Fosrenol works by binding to phosphate in food, it is most useful when taken with a meal.

Take your next scheduled dose with your next meal, unless your healthcare provider gives you different instructions.

Follow Your Phosphate-Controlled Diet

Fosrenol works best when combined with a phosphate-controlled diet.

Your kidney care team or dietitian may recommend limiting foods that are particularly high in phosphate or contain added phosphate ingredients.

The medication helps reduce phosphate absorption, but it does not replace dietary management.

Fosrenol and Dialysis

If you are receiving dialysis, continue attending all scheduled dialysis sessions.

Fosrenol and dialysis work in different ways. Dialysis removes some phosphate that is already in the bloodstream, while Fosrenol reduces how much phosphate from food is absorbed in the first place.

Tell Your Healthcare Provider About Other Medicines

Fosrenol can affect the absorption of some oral medications.

Tell your healthcare provider or pharmacist about all prescription medicines, over-the-counter products, vitamins, and supplements you take. Some medicines may need to be taken at a different time from Fosrenol.

If You Have Trouble Chewing

Tell your healthcare provider if you have poor dentition, dentures, swallowing difficulties, or problems chewing tablets.

Because Fosrenol tablets must be thoroughly chewed or crushed, your healthcare provider may need to give you additional instructions or consider another formulation.

When to Contact Your Healthcare Provider

Contact your healthcare provider if you develop persistent or severe digestive symptoms, such as significant abdominal pain, severe constipation, vomiting, or difficulty passing stool.

You should also contact your provider if your phosphate levels remain high despite taking Fosrenol as directed.

Getting the Best Results

For the best phosphate control, take Fosrenol with or immediately after meals, chew or crush the tablets completely, follow your prescribed daily dose, attend dialysis as scheduled, and complete regular blood testing.

Do not change the amount you take without speaking with your healthcare provider.

Gastrointestinal Side Effects

Fosrenol may cause digestive side effects, especially when treatment is first started.

Common problems can include nausea, vomiting, diarrhea, constipation, abdominal discomfort, or indigestion. Tell your healthcare provider if these symptoms become severe, persistent, or difficult to manage.

Bowel Obstruction and Severe Constipation

Fosrenol may not be appropriate for people with certain serious gastrointestinal conditions, such as bowel obstruction, ileus, or severe constipation.

Because the chewable tablets must be thoroughly broken down before swallowing, it is especially important to follow the administration instructions carefully.

Contact your healthcare provider promptly if you develop severe abdominal pain, persistent vomiting, significant bloating, or an inability to pass stool or gas.

Chewing the Tablets Properly Is Important

Fosrenol chewable tablets should be chewed completely or crushed before swallowing.

Do not swallow the tablets whole. This is particularly important for people with poor dental health, difficulty chewing, or swallowing problems because improperly chewed tablets may increase the risk of gastrointestinal complications.

Use in Older Adults

Older adults can use Fosrenol when prescribed, but they may be more likely to have underlying digestive problems or other medical conditions that require closer monitoring.

Your healthcare provider may pay particular attention to symptoms such as constipation, abdominal pain, or changes in bowel habits.

Medication Interactions

Fosrenol can interfere with the absorption of certain medications taken by mouth.

Tell your healthcare provider or pharmacist about all prescription medicines, over-the-counter products, vitamins, minerals, and supplements you use.

Some medicines may need to be taken several hours before or after Fosrenol so they can be absorbed properly.

Separating Other Medicines From Fosrenol

Certain medications are especially sensitive to changes in absorption when taken with phosphate binders.

Your healthcare provider or pharmacist can tell you whether a particular medicine should be separated from Fosrenol and how much time should be allowed between doses.

Do not change the timing of an important medication without professional advice.

Vitamins and Mineral Supplements

If you take iron, calcium, magnesium, or other mineral supplements, tell your healthcare provider.

Fosrenol can bind substances in the digestive tract, so your healthcare provider may recommend separating certain supplements from your Fosrenol dose.

Your need for mineral supplements should be based on your blood tests and overall treatment plan rather than taking them automatically.

Fosrenol Can Appear on X-Rays

Lanthanum has radiopaque properties, which means it can be visible on certain imaging tests.

Fosrenol tablets or lanthanum remaining in the digestive tract may therefore appear on an abdominal X-ray or other imaging study.

Tell the healthcare professional performing or interpreting an abdominal imaging test that you are taking Fosrenol.

Liver Problems

Lanthanum is eliminated mainly through the digestive system rather than through the kidneys.

However, people with significant liver or biliary problems may require additional caution because the liver and bile help process and eliminate absorbed lanthanum.

Tell your healthcare provider if you have liver disease before starting treatment.

Kidney Disease and Fosrenol

Fosrenol is specifically used in people with advanced kidney disease, including patients receiving dialysis.

Unlike many medications, lanthanum does not rely primarily on the kidneys for elimination. Therefore, reduced kidney function itself is not generally the reason for adjusting the dose.

Instead, dosing is mainly adjusted according to your blood phosphate levels and response to treatment.

Tell Your Healthcare Provider About Your Medical History

Before using Fosrenol, tell your healthcare provider about any history of bowel obstruction, severe constipation, gastrointestinal surgery, digestive disorders, liver problems, or difficulty chewing or swallowing.

This information helps your provider decide whether Fosrenol is appropriate and how closely you should be monitored.

Regular Monitoring

Your healthcare provider will monitor your serum phosphate levels while you are taking Fosrenol and may adjust your dose depending on the results.

Report significant digestive symptoms or any problems taking the tablets. Regular monitoring helps ensure that Fosrenol continues to control phosphate levels safely and effectively.

Is Fosrenol safe during pregnancy?

The safety of Fosrenol during pregnancy has not been fully established. Available human data are limited, and the current U.S. prescribing information recommends using a non-lanthanum phosphate binder during pregnancy when possible. If you are pregnant or planning to become pregnant, talk to your healthcare provider before using Fosrenol.

Can Fosrenol be used while breastfeeding?

There is not enough information to know whether lanthanum from Fosrenol passes into human breast milk or how it might affect a nursing infant. Because lanthanum has been found to deposit in developing bone in animal studies, the prescribing information recommends using a non-lanthanum phosphate binder while breastfeeding.

How often should I take Fosrenol?

Fosrenol is generally taken with or immediately after meals. Many patients take it three times a day with their main meals, but the exact schedule depends on your prescribed total daily dose and eating pattern. Your healthcare provider will determine how much you should take based mainly on your serum phosphate levels and response to treatment.

Why does Fosrenol need to be taken with meals?

Fosrenol works by binding to phosphate from food inside your digestive tract. Taking it with or immediately after eating allows the medication to trap dietary phosphate before it can be absorbed into your bloodstream.

How long does it take for Fosrenol to start working?

Fosrenol begins binding phosphate from food as soon as it is present in the digestive tract. However, it may take several weeks and one or more dose adjustments before your blood phosphate level reaches the desired range. Your healthcare provider will usually monitor your phosphate level and adjust your dose as needed.

Can Fosrenol interact with other medications?

Yes. Fosrenol can interfere with the absorption of certain medicines taken by mouth. Some medications that bind to minerals or antacids may need to be taken at least 2 hours apart from Fosrenol. For other important oral medicines, your healthcare provider or pharmacist may recommend a different amount of separation depending on how the drug is absorbed.

What about vitamins and mineral supplements?

Tell your healthcare provider if you take calcium, iron, magnesium, vitamins, or other mineral supplements. Some products may need to be taken at a different time from Fosrenol to avoid possible absorption problems. Do not automatically start or stop supplements without discussing them with your kidney care team.

Can Fosrenol be used in children?

Fosrenol is not currently recommended for pediatric patients in the U.S. Its safety and effectiveness in children have not been established. In animal studies, lanthanum was found to accumulate in developing bone, including the growth plate, and the long-term significance of this finding in children is unknown. Therefore, the statement that Fosrenol can routinely be used in children as young as 6 years old is not consistent with the current U.S. prescribing information.
