Side effects of Platless 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.
Clinical Studies Experience: Platless has been evaluated for safety in >44,000 patients, including >12,000 patients treated for ≥1 year. The clinically relevant adverse effects observed in the CAPRIE, CURE, CLARITY, COMMIT and ACTIVE-A studies are discussed as follows. Platless 75 mg/day was well tolerated compared to ASA 325 mg/day in CAPRIE. The overall tolerability of Platless in this study was similar to ASA, regardless of age, gender and ethnicity.
Haemorrhagic Disorders: In CAPRIE, in patients treated with either Platless or ASA, the overall incidence of any bleeding was 9.3%. The incidence of severe cases was 1.4% for Platless and 1.6% for ASA. In patients that received Platless, gastrointestinal bleeding occurred at a rate of 2% and required hospitalisation in 0.7%. In patients that received ASA, the corresponding rates were 2.7% and 1.1%, respectively.
The overall incidence of other bleedings was higher in patients that received Platless compared to ASA (7.3% vs 6.5%). However, the incidence of severe events was similar in both treatment groups (0.6% vs 0.4%). The most frequently reported events in both treatment groups were: Purpura/bruising and epistaxis. Other less frequently reported events were haematoma, haematuria and eye bleeding (mainly conjunctival).
The incidence of intracranial bleeding was 0.4% in patients that received Platless and 0.5% for patients that received ASA.
In CURE, the administration of Platless + ASA as compared to placebo + ASA was not associated with a statistically significant increase in life-threatening bleeds (event rates 2.2% vs 1.8%) or fatal bleeds (0.2% vs 0.2%), but the risk of major, minor and other bleedings was significantly higher with Platless + ASA: Major bleeds (3.7% Platless + ASA vs 2.7% placebo + ASA), non-life-threatening major bleeds (1.6% Platless + ASA vs 1% placebo + ASA), primarily gastrointestinal and at puncture sites, and minor bleeds (5.1% Platless + ASA vs 2.4% placebo + ASA). The incidence of intracranial bleeding was 0.1% in both groups.
The major bleeding event rate for Platless + ASA was dose-dependent on ASA (<100 mg: 2.6%; 100-200 mg: 3.5%; >200mg: 4.9%) as was the major bleeding event rate for placebo + ASA (<100 mg: 2%; 100-200 mg: 2.3%; >200 mg: 4%).
The risk of bleeding (life-threatening, major, minor, other) decreased during the course of the trial: 0-1 months [Platless: 599/6259 (9.6%); placebo: 413/6303 (6.6%)], 1-3 months [Platless: 276/6123 (4.5%); placebo: 144/6168 (2.3%)], 3-6 months [Platless: 228/6037 (3.8%); placebo: 99/6048 (1.6%)], 6-9 months [Platless: 162/5005 (3.2%); placebo: 74/4972 (1.5%)], 9-12 months [Platless: 73/3841 (1.9%); placebo: 40/3844 (1%)].
There was no excess in major bleeds within 7 days after coronary bypass graft surgery in patients who stopped therapy >5 days prior to surgery (4.4% Platless + ASA vs 5.3% placebo + ASA). In patients who remained on therapy within 5 days of bypass graft surgery, the event rate was 9.6% for Platless + ASA and 6.3% for placebo + ASA.
In CLARITY, there was an overall increase in bleeding in the Platless + ASA group (17.4%) versus the placebo + ASA group (12.9%). The incidence of major bleeding was similar between groups (1.3% vs 1.1% for the Platless + ASA and the placebo + ASA groups, respectively). This was consistent across subgroups of patients defined by baseline characteristics, and type of fibrinolytic or heparin therapy. The incidence of fatal bleeding (0.8% vs 0.6% in the Platless + ASA and the placebo + ASA groups, respectively) and intracranial hemorrhage (0.5% vs 0.7% in the Platless + ASA and the placebo + ASA groups, respectively) was low and similar in both groups.
In COMMIT, the overall rate of noncerebral major bleeding or cerebral bleedings was low and similar in both groups (0.6% vs 0.5% in the Platless + ASA and the placebo + ASA groups, respectively).
In ACTIVE-A, the rate of major bleeding was greater in the Platless + ASA group than in the placebo + ASA group (6.7% vs 4.3%). Major bleeding was mostly of extracranial origin in both groups (5.3% in the Platless + ASA group; 3.5% in the placebo + ASA group), mainly in the gastrointestinal tract (3.5% vs 1.8%). There was an excess of intracranial bleeding in the Platless + ASA treatment group compared to the placebo + ASA group (1.4% vs 0.8%, respectively). There was no statistically significant difference in the rates of fatal bleeding and hemorrhagic stroke (0.8% and 0.6%, respectively) between groups.
Haematological Disorders: In CAPRIE, severe neutropenia (<0.45 x 109/L) was observed in 4 patients (0.04%) that received Platless and 2 patients (0.02%) that received ASA. Two of the 9599 patients who received Platless and none of the 9586 patients who received ASA had neutrophil counts of zero.
One case of aplastic anaemia occurred on Platless treatment.
The incidence of severe thrombocytopenia (<80 x 109/L) was 0.2% on Platless and 0.1% on ASA; very rare cases of platelet count ≤30 g/L have been reported.
In CURE and CLARITY, the number of patients with thrombocytopenia or neutropenia was similar in both groups.

What is the most important information I should know about Platless?
Platless may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Platless with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Thrombotic thrombocytopenic purpura (TTP) is a serious, possibly fatal, condition that has occurred in patients who take Platless. It has sometimes occurred after taking Platless for short periods of time (eg, less than 2 weeks). Seek immediate medical attention if you have pale skin; purple skin patches; symptoms of hemolytic anemia (eg, unusual tiredness or weakness, fever or chills, stomach or back pain, yellowing of the eyes or skin); or unusual bruising or bleeding.
Platless may reduce the number of clot-forming cells (platelets) in your blood. Avoid activities that may cause bruising or injury. Tell your doctor if you have unusual bruising or bleeding. Tell your doctor if you have dark, tarry, or bloody stools.
Tell your doctor or dentist that you take Platless before you receive any medical or dental care, emergency care, or surgery. You may need to stop Platless before you have certain types of surgery.
Platless must be converted in the body for it to work. This conversion does not occur as well in some people (about 2% of white patients, 4% of black patients, and 14% of Chinese patients), and the medicine may not work as well in these patients. Your doctor may perform a test to check how well your body is able to convert Platless. Talk with your doctor for more information.
Platless should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
PREGNANCY and BREAST-FEEDING: If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Platless while you are pregnant. It is not known if Platless is found in breast milk. Do not breast-feed while taking Platless.
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.
Platless should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation.
Platless is contraindicated in patients with pheochro-mocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phen-tolamine.
Platless is contraindicated in patients with known sensitivity or intolerance to the drug.
Platless should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased.
