Pregnancy/Breast-Feeding
Implications |
|
It is not known whether sevelamer is excreted in human milk. Because
sevelamer may cause a reduction in the absorption of some vitamins, it should be
used with caution in pregnant and/or nursing women. |
|
|
Contraindications |
|
Hypersensitivity to sevelamer or any component of the formulation,
hypophosphatemia, or bowel obstruction |
|
|
Warnings/Precautions |
|
Use with caution in patients with gastrointestinal disorders including
dysphagia, swallowing disorders, severe gastrointestinal motility disorders, or
major gastrointestinal surgery. May cause reductions in vitamin D, E, K, and
folic acid absorption. Long-term studies of carcinogenic potential have not been
completed. Capsules should not be taken apart or chewed. |

Adverse
Reactions |
|
>10%:
Cardiovascular: Hypotension (11%), thrombosis (10%)
Central nervous system: Headache (10%)
Endocrine and metabolic: Decreased absorption of vitamins D, E, K and folic
acid
Gastrointestinal: Diarrhea (16%), dyspepsia (5% to 11%), vomiting (12%)
Neuromuscular and skeletal: Pain (13%)
Miscellaneous: Infection (15%)
1% to 10%:
Cardiovascular: Hypertension (9%)
Gastrointestinal: Nausea (7%), flatulence (4%), diarrhea (4%), constipation
(2%)
Respiratory: Cough (4%) |
|
|
Overdosage/Toxicology |
|
Sevelamer is not absorbed systemically. There are no reports of overdosage in
patients. |
|
|
Drug
Interactions |
|
No formal drug interaction studies have been undertaken. Sevelamer may bind
to some drugs in the gastrointestinal tract and decrease their absorption. When
changes in absorption of oral medications may have significant clinical
consequences (such as antiarrhythmic and antiseizure medications), these
medications should be taken at least 1 hour before or 3 hours after a dose of
sevelamer. |
|
|
Stability |
|
Store at controlled room temperature |
|
|
Mechanism of
Action |
|
Sevalamer (a polymeric compound) binds phosphate within the intestinal lumen,
limiting absorption and decreasing serum phosphate concentrations without
altering calcium, aluminum, or bicarbonate concentrations |
|
|
Pharmacodynamics/Kinetics |
|
Absorption: Not absorbed systemically
Elimination: Feces |
|
|
Usual Dosage |
|
Adults: Oral: 2-4 capsules 3 times/day with meals; the initial dose may be
based on serum phosphorous:
>6.0 mg/dL and <7.5 mg/dL: 2 capsules 3 times/day
>7.5 mg/dL and <9.0 mg/dL: 3 capsules 3 times/day
greater than or equal to 9.0 mg/dL: 4 capsules 3 times/day
Dosage should be adjusted based on serum phosphorous concentration, with a
goal of lowering to <6.0 mg/dL; maximum daily dose studied was 30
capsules/day. |

Patient
Information |
|
Take as directed, with meals. Do not break or chew capsule. You may
experience headache or dizziness (use caution when driving or engaging in tasks
requiring alertness until response to drug is known); upset stomach, nausea, or
vomiting (frequent small meals, frequent mouth care, or sucking hard candy may
help); diarrhea (yogurt or buttermilk may help); hypotension (use caution when
rising from sitting or lying position or when climbing stairs or bending over);
or mild neuromuscular pain or stiffness (mild analgesic may help). Report
persistent adverse reactions. Pregnancy/breast-feeding precautions:
