Side Effects

Quick Answer

Common side effects of Ticagrelor include breathlessness, bleeding (bruising, nosebleed, GI), headache, and dizziness. Serious effects include major bleeding (intracranial, GI) and ventricular pauses. Dyspnoea usually does not require stopping the medicine — seek guidance from a cardiologist. Never stop abruptly in ACS/stent.

Side Effects at a Glance

Common

Dyspnoea / breathlessness (15-20% patients — adenosine-mediated; NOT bronchospasm; usually self-limiting)
Bleeding — bruising, nosebleed (epistaxis), minor cuts with excessive bleeding
Gastrointestinal bleeding (dark stools, blood in stool)
Headache
Dizziness
Nausea
Hyperuricaemia (mild — usually asymptomatic; rarely gout)

Serious — See a Doctor

Major bleeding — intracranial haemorrhage (severe headache, neurological signs — EMERGENCY)
Fatal gastrointestinal bleeding (black tarry stools, vomiting blood)
Severe dyspnoea (rare — requires cardiologist evaluation)
Ventricular pauses with haemodynamic compromise (rare)

When to See a Doctor Immediately

Excessive or unusual bleeding — stop and seek care
Severe or rapidly worsening breathlessness
Severe bradycardia or fainting
Sudden severe chest pain (stent thrombosis if drug was stopped — EMERGENCY 1122)
Black or tarry stools, vomiting blood (GI bleeding)
Severe headache, vision changes, arm/leg weakness (intracranial bleeding — EMERGENCY)

Ticagrelor (Brilinta) Tablet Side Effects (Nuksanat)

Ticagrelor (Brilinta) is an antiplatelet medicine — its action is to inhibit platelets, so bleeding is an expected outcome. The most important and characteristic side effect is dyspnoea (breathlessness) which occurs only with ticagrelor and is often mistaken for bronchospasm — it is NOT bronchospasm.

Characteristic Side Effect: Dyspnoea (Sans Phoolna)

Ticagrelor causes breathlessness in 15–20% of patients:

Mechanism: Adenosine accumulation — ticagrelor inhibits adenosine uptake
What it is NOT: Bronchospasm, asthma attack, heart failure
Onset: Usually within the first week
Course: Often resolves on its own — if persistent, see a cardiologist
Action: Generally do NOT stop the medicine — there is a risk of stent thrombosis
Exception: Severe or worsening dyspnoea — cardiologist evaluation is essential

Common Side Effects (Aam Nuksanat)

Dyspnoea / breathlessness — 15–20% of patients; adenosine-mediated; NOT bronchospasm; usually self-limiting
Bleeding — bruising, nosebleed, excessive bleeding from minor cuts
GI bleeding — dark stools, blood in stool
Headache
Dizziness
Nausea
Hyperuricaemia — mild, usually asymptomatic; rarely gout

These side effects are generally manageable. Inform your doctor but do not stop on your own.

Uncommon Side Effects

Ventricular pauses — usually short, asymptomatic (Holter monitoring data shows this)
Sinus bradycardia (slow heart rate — adenosine)
Hypotension
Confusion (rare)

Serious Side Effects (Sanjeedah Nuksanat — Emergency)

Major bleeding — intracranial haemorrhage (severe headache, neurological signs) — EMERGENCY
Fatal GI bleeding — black tarry stools, vomiting blood — seek care immediately
Severe dyspnoea — rare; requires urgent cardiologist evaluation
Ventricular pauses with haemodynamic compromise — rare; pacemaker consideration

When to See a Doctor (Kab Doctor Se Milna Zaroori Hai)

Excessive or unusual bleeding — stop and seek care
Severe or rapidly worsening breathlessness
Severe bradycardia or fainting
Sudden severe chest pain
Black or tarry stools, vomiting blood
Severe headache, vision changes, arm/leg weakness (intracranial bleeding — EMERGENCY)

Warnings and Precautions (Ihtiyat)

Inform surgical/dental teams — stop 5 days before elective procedures
Do not take Aspirin >100mg — reduces ticagrelor efficacy
Avoid strong CYP3A4 inhibitors (ketoconazole, ritonavir, clarithromycin)
CONTRAINDICATED if previous intracranial haemorrhage
No antidote available — platelet transfusion is considered in bleeding emergencies

Frequently Asked Questions

Ticagrelor se sans kyun phoolta hai?

Ticagrelor causes dyspnoea (breathlessness) through accumulation of adenosine — this is not bronchospasm or an asthma attack. It occurs in 15–20% of patients, often more in the first weeks and then usually resolves on its own. Unless it is severe, do not stop the medicine. Inform your cardiologist.

Ticagrelor se bleeding kyun hoti hai?

Ticagrelor inhibits platelet aggregation — that is its intended action. However, the side effect is that minor cuts or nosebleeds produce more bleeding than usual. Major bleeding (black stools, blood in vomit, severe headache) is an emergency — seek care immediately.

Ticagrelor ka side effect feel ho to kya karein?

Mild dyspnoea — inform your cardiologist; do not stop the medicine (risk of stent thrombosis). Major bleeding — go to the emergency room immediately. Sudden chest pain (if drug was stopped) — call 1122.

Ticagrelor aur clopidogrel ki side effects kya farq hain?

Dyspnoea (breathlessness) and ventricular pauses are more common with Ticagrelor — these are ticagrelor-specific side effects (adenosine effect). Clopidogrel does not cause these. Bleeding risk is comparable in both.

Ticagrelor se allergic reaction ho sakti hai?

Yes — like any medicine, ticagrelor can cause an allergic reaction (rash, itching, swelling, anaphylaxis) but this is rare. Stop the medicine immediately and seek medical help.
