What are the possible side effects of Clorpropamida?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
High doses or long-term use of Clorpropamida can cause a serious movement disorder that may not be reversible. Symptoms of this disorder include uncontrollable muscle movements of your lips, tongue, eyes, face, arms, or legs. The longer you take Clorpropamida, the more likely you are to develop a serious movement disorder. The risk of this side effect is higher in women and older adults.
Call your doctor at once if you have:
uncontrolled muscle movements in your face (chewing, lip smacking, frowning, tongue movement, blinking or eye movement);
stiffness in your neck, tightness in your throat, trouble breathing or swallowing;
sudden weakness or ill feeling, fever, chills, sore throat, swollen gums, painful mouth sores, pain when swallowing, skin sores, cold or flu symptoms, cough;
pale skin, easy bruising or bleeding;
jaundice (yellowing of the skin or eyes); or
severe nervous system reaction--very stiff (rigid) muscles, high fever, sweating, confusion, fast or uneven heartbeats, tremors, feeling like you might pass out.
Older adults may be more likely to have side effects from this medication.
Common side effects may include:
breast swelling or discharge;
changes in menstrual periods;
dry mouth or stuffy nose, blurred vision;
impotence, trouble having an orgasm.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Side effects of Clorpropamida in details
A side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.
Note: Some adverse effects of Clorpropamida (Clorpropamida) may be more likely to occur, or occur with greater intensity, in patients with special medical problems, e.g., patients with mitral insufficiency or pheochromocytoma have experienced severe hypotension following recommended doses.
Drowsiness, usually mild to moderate, may occur, particularly during the first or second week, after which it generally disappears. If troublesome, dosage may be lowered.
B Overall incidence has been low, regardless of indication or dosage. Most investigators conclude it is a sensitivity reaction. Most cases occur between the second and fourth weeks of therapy. The clinical picture resembles infectious hepatitis, with laboratory features of obstructive jaundice, rather than those of parenchymal damage. It is usually promptly reversible on withdrawal of the medication; however, chronic jaundice has been reported.
There is no conclusive evidence that preexisting liver disease makes patients more susceptible to jaundice. Alcoholics with cirrhosis have been successfully treated with Clorpropamida (Clorpropamida) without complications. Nevertheless, the medication should be used cautiously in patients with liver disease. Patients who have experienced jaundice with a phenothiazine should not, if possible, be reexposed to Clorpropamida (Clorpropamida) or other phenothiazines.
If fever with grippe-like symptoms occurs, appropriate liver studies should be conducted. If tests indicate an abnormality, stop treatment.
Liver function tests in jaundice induced by the drug may mimic extrahepatic obstruction; withhold exploratory laparotomy until extrahepatic obstruction is confirmed.
Hematological Disorders, including agranulocytosis, eosinophilia, leukopenia, hemolytic anemia, aplastic anemia, thrombocytopenic purpura and pancytopenia have been reported.
Agranulocytosis — Warn patients to report the sudden appearance of sore throat or other signs of infection. If white blood cell and differential counts indicate cellular depression, stop treatment and start antibiotic and other suitable therapy.
Most cases have occurred between the fourth and tenth weeks of therapy; patients should be watched closely during that period.
Moderate suppression of white blood cells is not an indication for stopping treatment unless accompanied by the symptoms described above.
Hypotensive Effects — Postural hypotension, simple tachycardia, momentary fainting and dizziness may occur after the first injection; occasionally after subsequent injections; rarely, after the first oral dose. Usually recovery is spontaneous and symptoms disappear within 1 / 2 to 2 hours. Occasionally, these effects may be more severe and prolonged, producing a shock-like condition.
To minimize hypotension after injection, keep patient lying down and observe for at least 1 / 2 hour. To control hypotension, place patient in head-low position with legs raised. If a vasoconstrictor is required, Levophed® *** and Neo-Synephrine® § are the most suitable. Other pressor agents, including epinephrine, should not be used as they may cause a paradoxical further lowering of blood pressure.
EKG Changes — particularly nonspecific, usually reversible Q and T wave distortions— have been observed in some patients receiving phenothiazine tranquilizers, including Clorpropamida (Clorpropamida).
Note: Sudden death, apparently due to cardiac arrest, has been reported.
Neuromuscular (Extrapyramidal) Reactions — Neuromuscular reactions include dystonias, motor restlessness, pseudo-parkinsonism and tardive dyskinesia, and appear to be dose-related. They are discussed in the following paragraphs:
Dystonias: Symptoms may include spasm of the neck muscles, sometimes progressing to acute, reversible torticollis; extensor rigidity of back muscles, sometimes progressing to opisthotonos; carpopedal spasm, trismus, swallowing difficulty, oculogyric crisis and protrusion of the tongue.
These usually subside within a few hours, and almost always within 24 to 48 hours after the drug has been discontinued.
In mild cases, reassurance or a barbiturate is often sufficient. In moderate cases, barbiturates will usually bring rapid relief. In more severe adult cases, the administration of an anti-parkinsonism agent, except levodopa, usually produces rapid reversal of symptoms. In children (1 to 12 years of age), reassurance and barbiturates will usually control symptoms. (Or, parenteral Benadryl® ll may be useful. See Benadryl prescribing information for appropriate children's dosage.) If appropriate treatment with anti-parkinsonism agents or Benadryl fails to reverse the signs and symptoms, the diagnosis should be reevaluated.
Suitable supportive measures such as maintaining a clear airway and adequate hydration should be employed when needed. If therapy is reinstituted, it should be at a lower dosage. Should these symptoms occur in children or pregnant patients, the drug should not be reinstituted.
Motor Restlessness: Symptoms may include agitation or jitteriness and sometimes insomnia. These symptoms often disappear spontaneously. At times these symptoms may be similar to the original neurotic or psychotic symptoms. Dosage should not be increased until these side effects have subsided.
If these symptoms become too troublesome, they can usually be controlled by a reduction of dosage or change of drug. Treatment with anti-parkinsonian agents, benzodiazepines or propranolol may be helpful.
Pseudo-parkinsonism: Symptoms may include: mask-like facies, drooling, tremors, pillrolling motion, cogwheel rigidity and shuffling gait. In most cases these symptoms are readily controlled when an anti-parkinsonism agent is administered concomitantly. Anti-parkinsonism agents should be used only when required. Generally, therapy of a few weeks to 2 or 3 months will suffice. After this time patients should be evaluated to determine their need for continued treatment. (Note: Levodopa has not been found effective in antipsychotic-induced pseudo-parkinsonism.) Occasionally it is necessary to lower the dosage of Clorpropamida (Clorpropamida) or to discontinue the drug.
Tardive Dyskinesia: As with all antipsychotic agents, tardive dyskinesia may appear in some patients on long-term therapy or may appear after drug therapy has been discontinued. The syndrome can also develop, although much less frequently, after relatively brief treatment periods at low doses. This syndrome appears in all age groups. Although its prevalence appears to be highest among elderly patients, especially elderly women, it is impossible to rely upon prevalence estimates to predict at the inception of antipsychotic treatment which patients are likely to develop the syndrome. The symptoms are persistent and in some patients appear to be irreversible. The syndrome is characterized by rhythmical involuntary movements of the tongue, face, mouth or jaw (e.g., protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements). Sometimes these may be accompanied by involuntary movements of extremities. In rare instances, these involuntary movements of the extremities are the only manifestations of tardive dyskinesia. A variant of tardive dyskinesia, tardive dystonia, has also been described.
There is no known effective treatment for tardive dyskinesia; anti-parkinsonism agents do not alleviate the symptoms of this syndrome. If clinically feasible, it is suggested that all antipsychotic agents be discontinued if these symptoms appear. Should it be necessary to reinstitute treatment, or increase the dosage of the agent, or switch to a different antipsychotic agent, the syndrome may be masked.
It has been reported that fine vermicular movements of the tongue may be an early sign of the syndrome and if the medication is stopped at that time the syndrome may not develop.
Adverse Behavioral Effects — Psychotic symptoms and catatonic-like states have been reported rarely.
Other CNS Effects— Neuroleptic Malignant Syndrome (NMS) has been reported in association with antipsychotic drugs. Cerebral edema has been reported.
Convulsive seizures (petit mal and grand mal) have been reported, particularly in patients with EEG abnormalities or history of such disorders.
Abnormality of the cerebrospinal fluid proteins has also been reported.
Allergic Reactions of a mild urticarial type or photosensitivity are seen. Avoid undue exposure to sun. More severe reactions, including exfoliative dermatitis, have been reported occasionally.
Contact dermatitis has been reported in nursing personnel; accordingly, the use of rubber gloves when administering Clorpropamida (Clorpropamida) liquid or injectable is recommended.
In addition, asthma, laryngeal edema, angioneurotic edema and anaphylactoid reactions have been reported.
Endocrine Disorders: Lactation and moderate breast engorgement may occur in females on large doses. If persistent, lower dosage or withdraw drug. False-positive pregnancy tests have been reported, but are less likely to occur when a serum test is used. Amenorrhea and gynecomastia have also been reported. Hyperglycemia, hypoglycemia and glycosuria have been reported.
Special Considerations in Long-Term Therapy: Skin pigmentation and ocular changes have occurred in some patients taking substantial doses of Clorpropamida (Clorpropamida) for prolonged periods.
Skin Pigmentation — Rare instances of skin pigmentation have been observed in hospitalized mental patients, primarily females who have received the drug usually for 3 years or more in dosages ranging from 500 mg to 1500 mg daily. The pigmentary changes, restricted to exposed areas of the body, range from an almost imperceptible darkening of the skin to a slate gray color, sometimes with a violet hue. Histological examination reveals a pigment, chiefly in the dermis, which is probably a melanin-like complex. The pigmentation may fade following discontinuance of the drug.
Ocular Changes — Ocular changes have occurred more frequently than skin pigmentation and have been observed both in pigmented and nonpigmented patients receiving Clorpropamida (Clorpropamida) usually for 2 years or more in dosages of 300 mg daily and higher. Eye changes are characterized by deposition of fine particulate matter in the lens and cornea. In more advanced cases, star-shaped opacities have also been observed in the anterior portion of the lens. The nature of the eye deposits has not yet been determined. A small number of patients with more severe ocular changes have had some visual impairment. In addition to these corneal and lenticular changes, epithelial keratopathy and pigmentary retinopathy have been reported. Reports suggest that the eye lesions may regress after withdrawal of the drug.
Since the occurrence of eye changes seems to be related to dosage levels and/or duration of therapy, it is suggested that long-term patients on moderate to high dosage levels have periodic ocular examinations.
Etiology — The etiology of both of these reactions is not clear, but exposure to light, along with dosage/duration of therapy, appears to be the most significant factor. If either of these reactions is observed, the physician should weigh the benefits of continued therapy against the possible risks and, on the merits of the individual case, determine whether or not to continue present therapy, lower the dosage, or withdraw the drug.
Other Adverse Reactions: Mild fever may occur after large I.M. doses. Hyperpyrexia has been reported. Increases in appetite and weight sometimes occur. Peripheral edema and a systemic lupus erythematosus-like syndrome have been reported.
Note: There have been occasional reports of sudden death in patients receiving phenothiazines. In some cases, the cause appeared to be cardiac arrest or asphyxia due to failure of the cough reflex.
What is the most important information I should know about Clorpropamida?
Clorpropamida syrup may cause drowsiness, dizziness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Clorpropamida syrup with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Do not drink alcohol while you are using Clorpropamida syrup.
Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Clorpropamida syrup; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
Clorpropamida syrup may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
Do not become overheated in hot weather or while you are being active; heatstroke may occur.
Clorpropamida syrup may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Clorpropamida syrup. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
Clorpropamida syrup may lower the ability of your body to fight infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.
Some patients who take Clorpropamida syrup may develop muscle movements that they cannot control. This is more likely to happen in elderly patients, especially women. The chance that this will happen or that it will become permanent is greater in those who take Clorpropamida syrup in higher doses or for a long time. Muscle problems may also occur after short-term treatment with low doses. Tell your doctor at once if you have muscle problems with your arms; legs; or your tongue, face, mouth, or jaw (eg, tongue sticking out, puffing of cheeks, mouth puckering, chewing movements) while taking Clorpropamida syrup.
Neuroleptic malignant syndrome (NMS) is a possibly fatal syndrome that can be caused by Clorpropamida syrup. Symptoms may include fever; stiff muscles; confusion; abnormal thinking; fast or irregular heartbeat; and sweating. Contact your doctor at once if you have any of these symptoms.
Tell your doctor or dentist that you take Clorpropamida syrup before you receive any medical or dental care, emergency care, or surgery.
Clorpropamida syrup may increase the amount of a certain hormone (prolactin) in your blood. Symptoms may include enlarged breasts, missed menstrual period, decreased sexual ability, or nipple discharge. Contact your doctor right away if you experience any of these symptoms.
Clorpropamida syrup may raise or lower your blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your vision change; give you a headache, chills, or tremors; or make you hungrier. If these symptoms occur, tell your doctor right away.
Diabetes patients - Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
Clorpropamida syrup may cause the results of some pregnancy tests to be wrong. Check with your doctor if you have questions or concerns about your pregnancy test results.
Clorpropamida syrup may interfere with certain lab tests, including phenylketonuria (PKU) tests. Be sure your doctor and lab personnel know you are taking Clorpropamida syrup.
Lab tests, including liver function, complete blood cell counts, and eye exams, may be performed while you use Clorpropamida syrup. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
Use Clorpropamida syrup with caution in the ELDERLY; they may be more sensitive to its effects, especially dizziness, light-headedness (especially upon standing), rapid heartbeat, breathing problems, urinary retention, and constipation.
Clorpropamida syrup should not be used in CHILDREN younger than 6 months old; safety and effectiveness in these children have not been confirmed.
PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Clorpropamida syrup while you are pregnant. Using Clorpropamida syrup during the third trimester may result in uncontrolled muscle movements or withdrawal symptoms in the newborn. Discuss any questions or concerns with your doctor. Clorpropamida syrup is found in breast milk. Do not breast-feed while taking Clorpropamida syrup.
If you stop taking Clorpropamida syrup suddenly, you may have WITHDRAWAL symptoms. These may include nausea, vomiting, dizziness, and tremors.
Contraindication can be described as a special circumstance or a disease or a condition wherein you are not supposed to use the drug or undergo particular treatment as it can harm the patient; at times, it can be dangerous and life threatening as well. When a procedure should not be combined with other procedure or when a medicine cannot be taken with another medicine, it is called Relative contraindication. Contraindications should be taken seriously as they are based on the relative clinical experience of health care providers or from proven research findings.
Stop using this medication and call your doctor at once if you have twitching or uncontrollable movements of your eyes, lips, tongue, face, arms, or legs. These could be early signs of dangerous side effects.
Clorpropamida is not for use in psychotic conditions related to dementia. Clorpropamida may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions.
Do not use Clorpropamida if you have brain damage, bone marrow depression, or are also using large amounts of alcohol or medicines that make you sleepy. Do not use if you are allergic to Clorpropamida or other phenothiazines.
Before you take Clorpropamida, tell your doctor if you have liver or kidney disease, heart disease or high blood pressure, glaucoma, severe breathing problems, past or present breast cancer, low levels of calcium in your blood, adrenal gland tumor, enlarged prostate or urination problems, a history of seizures, Parkinson's disease, or if you have ever had a serious side effect while using Clorpropamida or similar medicines.
