Ticagrelor Side Effects
Commonly reported side effects of ticagrelor include: dyspnea. Continue reading for a comprehensive list of adverse effects.
Applies to ticagrelor: oral tablet.
Oral route (Tablet)
Ticagrelor can cause significant, sometimes fatal, bleeding. Do not use in patients with active pathological bleeding or history of intracranial hemorrhage. Do not start in patients undergoing urgent CABG. If possible, manage bleeding without discontinuing ticagrelor. Stopping ticagrelor increases the risk of subsequent cardiovascular events. Maintenance doses of aspirin above 100 mg in patients with acute coronary syndrome reduce the effectiveness of ticagrelor and should be avoided.
Serious side effects of Ticagrelor
Along with its needed effects, ticagrelor may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur while taking ticagrelor:
- Back pain
- bleeding gums
- blurred vision
- chest pain, tightness, or discomfort
- coughing up blood
- difficult or trouble breathing
- dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position
- fast, slow, or irregular heartbeat
- increased menstrual flow or vaginal bleeding
- lightheadedness, dizziness, or fainting
- loss of consciousness
- nausea or vomiting
- pounding in the ears

- red or dark brown urine
- unusual bleeding or bruising
- unusual tiredness or weakness
- Change in mental status
- difficulty in speaking
- pale skin
- pinpoint red spots on the skin
- yellow eyes or skin
Incidence not known
- Difficulty with swallowing
- large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs
Other side effects of Ticagrelor
Some side effects of ticagrelor may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects.
Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
For Healthcare Professionals
Applies to ticagrelor: oral tablet.
The most commonly reported side effects were bleeding and dyspnea.[Ref]
Very common (10% or more): Bleeding (12%)
Postmarketing reports: Thrombotic thrombocytopenic purpura[Ref]
In the PLATO study (PLATelet Inhibition and Patient Outcomes, n= 18,624), 9235 patients were treated with ticagrelor 90 mg orally twice a day. Patients were evaluated for non-CABG related major or minor bleeds compared to clopidogrel (n=9186). A minor bleed required medical intervention to stop or treat bleeding, whereas a major bleed included any of the following: fatal, intracranial, intrapericardial with cardiac tamponade, hypovolemic shock or severe hypotension requiring intervention, significantly disabling (e.g., intraocular with permanent vision loss), a decrease in hemoglobin of at least 3 g/dL (or a fall in hematocrit of at least 9%), or a transfusion of 2 or more units. A major bleed that was fatal/life-threatening was any of the events described as a major bleed plus a decrease in hemoglobin of more than 5 g/dL, a fall in hematocrit of at least 15%, or a transfusion of 4 or more units. A fatal bleed was a bleeding event that directly led to death within 7 days. For ticagrelor, the incidence of major and minor bleeds was 7.7% (clopidogrel 6.2%). These findings are broken down as followed: Major bleed (3.9%) major bleed fatal/life threatening (1.9%), fatal (0.2%), and intracranial hemorrhage fatal/life threatening (0.3%). Approximately half of the non-CABG major bleeding events occurred in the first 30 days.
In the PLATO study, when antiplatelet therapy was stopped 5 days prior to CABG, major bleeding occurred in 75% and 79% of patients receiving ticagrelor or clopidogrel, respectively.[Ref]
During the PLATO study, (PLATelet Inhibition and Patient Outcomes, n= 18,624), dyspnea was reported in 13.8% of ticagrelor-treated patients, it was usually mild to moderate in intensity and often resolved during continued treatment, however, drug discontinuation was required in 0.9% of patients. In the PEGASUS study (n=21,162), 4.3% of patients taking ticagrelor 60 mg orally twice a day discontinued treatment due to dyspnea compared to 0.7% receiving aspirin alone. In a substudy of PLATO, 199 subjects underwent pulmonary function testing irrespective of whether they reported dyspnea. There was no indication of an adverse effect on pulmonary function assessed after one month or after at least 6 months of chronic treatment. During the THEMIS study (n=19,220), dyspnea was reported in 21% of ticagrelor-treated patients which led to drug discontinuation in 6.9% of patients.[Ref]
Very common (10% or more): Dyspnea (up to 21%)
Common (1% to 10%): Epistaxis, cough
Uncommon (0.1% to 1%): Hemoptysis
Postmarketing reports: Central sleep apnea, Cheyne-Stokes respiration[Ref]
In a Holter substudy of approximately 3000 patients from the PLATelet Inhibition and Patient Outcomes study, (PLATO, n= 18,624), more patients had ventricular pauses 3 seconds or longer with ticagrelor (6%) than with clopidogrel (3.5%) in the acute phase and 2.2% and 1.6% respectively after 1 month. Patients that were at an increased risk for bradycardic events were excluded from these studies. Patients with congestive heart failure (CHF) who were taking ticagrelor experienced ventricular pauses at a higher rate (9.2%) than those without CHF (5.4).[Ref]
Common (1% to 10%): Ventricular pauses, cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, bradycardia, cardiac failure, atrial fibrillation, peripheral edema, hypertension, hypotension, syncope, pre-syncope
Uncommon (0.1% to 1%): Non-cardiac chest pain
Postmarketing reports: Atrioventricular block[Ref]
Common (1% to 10%): Serum creatinine elevations[Ref]
During the PLATO study, (PLATelet Inhibition and Patient Outcomes, n= 18,624), serum creatinine levels increased by more than 50% in 7.4% of patients receiving ticagrelor 90 mg orally. Levels did not continue to increase with ongoing treatment and often decreased with continued therapy. Reversibility occurred upon discontinuation even in those patients with the greatest increase in levels during treatment. Treatment groups did not differ for renal related serious adverse events (e.g. acute renal failure, chronic renal failure, toxic nephropathy, or oliguria).[Ref]
Common (1% to 10%): Back pain
Rare (0.01% to 0.1%): Hemarthrosis[Ref]
Postmarketing reports: Hypersensitivity reactions including angioedema[Ref]
Common (1% to 10%): Dizziness, loss of consciousness
Uncommon (0.1% to 1%): Intracranial hemorrhage, paresthesia, headache[Ref]
Common (1% to 10%): Abdominal pain, dyspepsia, gastrointestinal hemorrhage, nausea, diarrhea, constipation, vomiting
Uncommon (0.1% to 1%): Retroperitoneal hemorrhage, gastritis, hematemesis, gastrointestinal ulcer hemorrhage, hemorrhoidal hemorrhage, oral hemorrhage[Ref]
Uncommon (0.1% to 1%): Gout
Rare (0.01% to 0.1%): Hyperuricemia[Ref]
In the PLATelet Inhibition and Patient Outcomes Study (PLATO, n= 18,624) the serum uric acid levels of patients taking ticagrelor 90 mg orally twice a day increased approximately 0.6 mg/dL from baseline. The difference disappeared within 30 days of stopping treatment. Gout occurred in 0.6% of patients.[Ref]
Common (1% to 10%): Urinary tract bleeding
Uncommon (0.1% to 1%): Vaginal bleeding[Ref]
Common (1% to 10%): Rash, pruritus, subcutaneous or dermal bleeding, bruising[Ref]
Uncommon (0.1% to 1%): Eye hemorrhage[Ref]
Common (1% to 10%): Vertigo, post procedural hemorrhage, fatigue, pyrexia
Uncommon (0.1% to 1%): Ear hemorrhage, wound hemorrhage, traumatic hemorrhage[Ref]
Rare (0.01% to 0.1%): Confusion[Ref]
