Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

  • Stay out of direct sunlight, especially between the hours of 10:00 a.m. and 3:00 p.m., if possible.

  • Wear protective clothing, including a hat. Also, wear sunglasses.

  • Apply a sun block product that has a skin protection factor (SPF) of at least 15. Some patients may require a product with a higher SPF number, especially if they have a fair complexion. If you have any questions about this, check with your doctor.

  • Apply a sun block lipstick that has an SPF of at least 15 to protect your lips.

  • Do not use a sunlamp or tanning bed or booth.

If you have a severe reaction from the sun, check with your doctor.


For diabetic patients:


  • Carbamazepine may affect urine sugar levels. While you are using this medicine, be especially careful when testing for sugar in your urine. If you notice a change in the results of your urine sugar tests or have any questions about this, check with your doctor.

Before having any medical tests, tell the medical doctor in charge that you or your child are taking this medicine. The results of some pregnancy tests and the metyrapone test may be affected by this medicine.


Before having any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are taking this medicine. Taking carbamazepine together with medicines that are used during surgery or dental or emergency treatments may increase the CNS depressant effects and cause other unwanted effects.


Your doctor may want you to carry a medical identification card or bracelet stating that you are taking this medicine.


Do not stop suddenly taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping completely. This may help prevent worsening of seizures.

Uses for Capoten


Hypertension


Management of hypertension (alone or in combination with other classes of antihypertensive agents).100 115 215 259 316 317


One of several preferred initial therapies in hypertensive patients with heart failure, postmyocardial infarction, high coronary disease risk, diabetes mellitus, chronic renal failure, and/or cerebrovascular disease.382


Can be used as monotherapy for initial management of uncomplicated hypertension;115 however, thiazide diuretics are preferred by JNC 7.382

Capoten Dosage and Administration


Administration


Oral Administration


Administer orally 1 hour before meals to maximize absorption.115


Dosage


Pediatric Patients


Hypertension

Oral

Dosage has been reduced in proportion to body weight; titrate carefully.115 Some experts recommend an initial dosage of 0.9–1.5 mg/kg daily (given as 0.3–0.5 mg/kg 3 times daily).398 Increase dosage as necessary to a maximum of 6 mg/kg daily.398


Adults


Hypertension

Oral

Initially, 25 mg 2 or 3 times daily.115 316 382 If BP is not adequately controlled after 1–2 weeks, increase dosage to 50 mg 2 or 3 times daily.115


Lower initial dosages (e.g., 6.25 mg twice daily to 12.5 mg 3 times daily) may be effective in some patients, particularly those already receiving a diuretic.a (See Hypotension under Cautions.)


Usual dosage: Manufacturers recommend 25–150 mg 2 or 3 times daily (usually not necessary to exceed 450 mg daily).115 316 JNC 7 recommends 25–100 mg daily given in 2 divided doses; JNC 7 recommends adding another drug, if needed, rather than continuing to increase dosage.382


If combination therapy is initiated with captopril/hydrochlorothiazide fixed-combination preparation, captopril 25 mg and hydrochlorothiazide 15 mg daily initially;102 259 adjust dosage (generally at 6-week intervals) by administering each drug separately or by advancing the fixed-combination preparation.102 259


Hypertensive Crises

Oral

25 mg 2 or 3 times daily, initiated promptly under close supervision with frequent monitoring of BP.115 May continue previous diuretic therapy, but discontinue other hypotensive agents.115 May increase dosage at intervals of ≤24 hours under continuous supervision until optimum BP response is attained or 450 mg daily is given.115 Adjunctive therapy with other hypotensive agents may be necessary.a


Acute therapy (e.g., 12.5–25 mg, repeated once or twice if necessary at intervals of 30–60 minutes or longer) has been effective231 232 236 259 in adults with hypertensive urgencies231 232 259 and emergencies.233 234 235 236 237 238 259 310


Nephropathy

Diabetic Nephropathy

Oral

25 mg 3 times daily.115 262


CHF

Oral

Manufacturers recommend initial dosage of 25 mg 3 times daily;115 in patients with normal or low BP who may be volume- and/or salt-depleted, initial dosage of 6.25 or 12.5 mg 3 times daily.115 Increase dosage gradually to 50 mg 3 times daily; delay further dosage increases for ≥2 weeks to assess response.115


Some clinicians recommend initial dosage of 6.25 or 12.5 mg 3 times daily, with gradual titration over several weeks to 50 mg 3 times daily, regardless of BP, salt/volume status, or concomitant diuretic therapy.321 333 377 Generally titrate dosage to prespecified target (i.e., ≥150 mg daily) or highest tolerated dosage rather than according to response.333 377


Left Ventricular Dysfunction after AMI

Oral

Manufacturers recommend initiation of therapy ≥3 days post-MI with single dose of 6.25 mg, followed by 12.5 mg 3 times daily.115 Increase dosage over next several days to 25 mg 3 times daily and then over next several weeks (as tolerated) to 50 mg 3 times daily.115


Some clinicians recommend initiation of therapy <24 hours post-MI with initial dose of 6.25 mg, followed by 12.5 mg 2 hours later, 25 mg 10–12 hours later, and then 50 mg twice daily as tolerated.319 Recommended maintenance dosage: 50 mg 3 times daily.115


Prescribing Limits


Pediatric Patients


Hypertension

Oral

Maximum 6 mg/kg daily.398


Adults


Hypertension

Oral

Maximum 450 mg daily.115


Dosage of captopril/hydrochlorothiazide fixed-combination generally should not exceed captopril 150 mg and hydrochlorothiazide 50 mg daily.102


CHF

Oral

Maximum dosage recommended by manufacturer and some experts is 450 mg daily.115 333 Other experts suggest maximum dosage of 50 mg 3 times daily.377


Special Populations


Renal Impairment


Manufacturers recommend initial dosage of <75 mg daily; increase dosage in small increments at 1- to 2-week intervals.115 After desired therapeutic effect has been attained, slowly reduce dosage to minimum effective level.115


Patients with Clcr 10–50 mL/minute: 75% of usual captopril dosage or administration of usual dose every 12–18 hours suggested by some clinicians.211


Clcr <10 mL/minute: 50% of usual dosage or administration of usual dose every 24 hours suggested by some clinicians.211


Patients undergoing hemodialysis may require supplemental dose after dialysis.211


Fixed-combination captopril/hydrochlorothiazide tablets usually are not recommended for patients with severe renal impairment.102


Geriatric Patients


Hypertension

Usual adult dosages generally have been used; dosages of 6.25–12.5 mg 1–4 times daily used occasionally.175


Volume-and/or Salt-Depleted Patients


Correct volume and/or salt depletion prior to initiation of therapy or initiate therapy under close medical supervision using lower initial dosage.115 116 148 153 (See Dosage: CHF, under Dosage and Administration.)


Cautions for Capoten


Contraindications



  • Known hypersensitivity (e.g. history of angioedema) to captopril or another ACE inhibitor.115 147 325 326 333



Warnings/Precautions


Warnings


Hematologic Effects

Possible neutropenia or agranulocytosis; risk of neutropenia appears to depend principally on degree of renal impairment and presence of collagen vascular disease (e.g., systemic lupus erythematosus, scleroderma).115


Use with caution and only after careful risk/benefit assessment in patients with collagen vascular disease or those taking drugs known to affect leukocytes or immune response.115


If used in patients with renal impairment, determine complete and differential leukocyte counts prior to initiation of therapy, at about 2-week intervals for the first 3 months of therapy, and periodically thereafter.115 Discontinue therapy if confirmed neutrophil count is <1000/mm3.115


Proteinuria

Proteinuria possible, particularly in patients with prior renal disease and/or those receiving relatively high dosages (>150 mg daily).115 Usually occurs by the 8th month of treatment1 3 46 and subsides or clears within 6 months whether or not therapy is continued;115 however, may persist in some patients.a


Hypotension

Possible excessive hypotension, particularly in volume- and/or salt-depleted patients (e.g., those treated with diuretics or undergoing dialysis, patients with severe CHF).1 5 17 23 25 31 66 85 115 116 148 154 156


Hypotension may occur in patients undergoing surgery or during anesthesia with agents that produce hypotension; recommended treatment is fluid volume expansion.115


Transient hypotension is not a contraindication to additional doses; may reinstate therapy cautiously after BP is stabilized (e.g., with volume expansion).115


To minimize potential for hypotension, consider recent antihypertensive therapy, extent of BP elevation, sodium intake, fluid status, and other clinical conditions.a (See Special Populations under Dosage and Administration.) Discontinue other antihypertensive therapy, if possible, 1 week before initiating captopril, except in patients with severe hypertension.115 a Withholding diuretic therapy and/or increasing sodium intake approximately 3–7 days prior to initiation of captopril may minimize potential for severe hypotension.115 116 148 153


Initiate therapy in patients with CHF under close medical supervision; monitor closely for first 2 weeks following initiation of captopril or any increase in captopril or diuretic dosage.115


Fetal/Neonatal Morbidity and Mortality

Possible fetal and neonatal morbidity and mortality when used during pregnancy.102 115 239 240 241 402 (See Boxed Warning.) Such potential risks occur throughout pregnancy, especially during the second and third trimesters.402


Also may increase the risk of major congenital malformations when administered during the first trimester of pregnancy.401 402


Discontinue as soon as possible when pregnancy is detected, unless continued use is considered lifesaving.402 Nearly all women can be transferred successfully to alternative therapy for the remainder of their pregnancy.239


Hepatic Effects

Clinical syndrome that usually is manifested initially by cholestatic jaundice and may progress to fulminant hepatic necrosis (occasionally fatal) reported rarely with ACE inhibitors.102 115 370


If jaundice or marked elevation of liver enzymes occurs, discontinue drug and monitor patient.115


Sensitivity Reactions


Anaphylactoid reactions and/or angioedema possible; if associated with laryngeal edema, may be fatal.115 333 Immediate medical intervention (e.g., epinephrine) for involvement of tongue, glottis, or larynx.115 Intestinal angioedema possible; consider in differential diagnosis of patients who develop abdominal pain.115


Anaphylactoid reactions reported in patients receiving ACE inhibitors while undergoing LDL apheresis with dextran sulfate absorption115 275 276 277 or following initiation of hemodialysis that utilized high-flux membrane.102 115 242 243 244


Life-threatening anaphylactoid reactions reported in at least 2 patients receiving ACE inhibitors while undergoing desensitization treatment with hymenoptera venom.102 155 278


Not recommended in patients with a history of angioedema associated with or unrelated to ACE inhibitors.a


General Precautions


Renal Effects

Transient increases in BUN and Scr possible, especially in patients with preexisting renal impairment, sodium depletion, or hypovolemia; patients with renovascular hypertension, particularly those with bilateral renal-artery stenosis or those with renal-artery stenosis in a solitary kidney;5 86 115 117 122 123 124 207 208 209 333 372 or patients with chronic or severe hypertension in whom the glomerular filtration rate may decrease transiently.1 115


Possible increases in BUN and Scr in patients with CHF;115 206 333 rapidity of onset and magnitude may depend in part on degree of sodium depletion.148 156 206 372


Closely monitor renal function following initiation of therapy in such patients.86 87 115 117 122 123 124 333 372 Some patients may require dosage reduction or discontinuance of ACE inhibitor or diuretic and/or adequate sodium repletion.115 156 206 207 209


Hyperkalemia

Possible hyperkalemia,5 7 38 69 70 85 115 122 125 126 162 163 164 177 especially in patients with impaired renal function, CHF, or diabetes mellitus and those receiving drugs that can increase serum potassium concentration (e.g., potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes).38 85 115 125 126 148 162 163 164 333 372 (See Interactions.)


Monitor serum potassium concentration carefully in these patients.126 162 163


Cough

Persistent and nonproductive cough; resolves after drug discontinuance.102 115 333


Valvular Stenosis

Possible risk of decreased coronary perfusion in patients with aortic stenosis when treated with captopril.a 115


Use of Fixed Combinations

When used in fixed combination with hydrochlorothiazide, consider the cautions, precautions, and contraindications associated with hydrochlorothiazide.102


Specific Populations

Pediatric Use

Safety and efficacy not established; however, captopril has been used in children.115 Manufacturer states that captopril should be used only when other measures for controlling BP have not been effective.115


Possible excessive, prolonged, and unpredictable decreases in BP and associated complications (e.g., oliguria, seizures) in infants.115


Renal Impairment

Systemic exposure to captopril may be increased.115 (See Special Populations under Pharmacokinetics.) Initial dosage adjustment recommended in patients with severe renal impairment.115 (See Renal Impairment under Dosage and Administration.)
