Two prescribed medicines
They work together to reduce platelet clumping.
Protect blood flow
DAPT helps prevent a clot inside the stent.
Follow your medicine plan
Use reminders and refill before tablets run out.
The stent and the medicines work together
You may feel well after a stent procedure and wonder whether both prescribed medicines are still necessary. A clot can form inside a stent without an early warning. This is called stent thrombosis. It can block blood flow and cause a stroke, heart attack or loss of blood supply to a limb, depending on where the stent is.
Keep taking both medicines for the period your treating team has prescribed, even when you feel well. Do not stop, reduce or replace either medicine on your own.
What is DAPT?
DAPT means dual antiplatelet therapy: two medicines that make platelets less likely to stick together and form a clot. It usually combines aspirin with another antiplatelet, such as clopidogrel or ticagrelor. They act through different pathways.
These medicines help prevent clots; they do not dissolve an established stent clot. Two medicines does not necessarily mean two tablets each day: a combination tablet may contain both medicines, and dosing schedules differ. Follow the names, strengths and timings on your prescription. Ask your pharmacist to explain any unfamiliar brand.
Why this matters after a brain or neck stent
A stent leaves a foreign surface inside an artery, where platelets can collect. A flow diverter used for a brain aneurysm is also a device inside the parent artery. The medicine plan before and after these procedures is an important part of protecting blood flow.
Carotid stents in the neck, stents in other arteries and heart stents also need an individual antiplatelet plan. This article applies when your team has prescribed DAPT after stenting. It does not mean every stent needs the same medicines or duration.
How long should I take both medicines?
The answer depends on the stent, its location, why it was placed, and your risks of clotting and bleeding. Your specialist may later change treatment to one medicine. That change should be planned; a follow-up date or an empty strip of tablets is not a stopping instruction.
Keep a written plan stating each medicine, its dose and timing, the review date and who can authorise a change. If the discharge instructions are unclear or another doctor advises stopping a medicine, ask the stent-treating team to coordinate the decision.
If a dose is missed or your supply runs out
Check the instructions for the exact medicine and contact your pharmacist or treating team promptly if unsure. Missed-dose advice differs between drugs. Do not double a dose to catch up. If you have missed several doses, have run out, or cannot keep medicines down, contact the stent-treating team the same day; do not wait for the next routine visit.
Use reminders that match your prescription and arrange refills before the supply ends. When travelling, carry your medicine list and enough tablets. Tell the team early if cost, swallowing or side effects make regular treatment difficult.
Bleeding: when to ask for help
Bruising and minor bleeding can happen on DAPT. Report repeated nosebleeds, unusually heavy periods or troublesome bruising so the team can assess them. Do not quietly skip tablets to manage these symptoms.
Blood in urine, black tar-like stools or a head injury needs urgent medical assessment, even if you initially feel well.
Call 108 for heavy or persistent bleeding, vomiting blood, fainting, new chest pain, sudden weakness or speech difficulty, or a sudden severe headache. A suddenly painful, cold or numb limb also needs emergency care. Do not drive yourself. Tell the emergency team which medicines you take and when you last took them; they will decide how to manage the next doses.
Before dental work, surgery or another procedure
Tell the dentist, surgeon or other clinician about your stent and both medicines before treatment is arranged. Any interruption must be coordinated with the team responsible for the stent. Some care can proceed while medicines continue; other procedures may need a different timing or a written interruption-and-restart plan.
Do not stop tablets simply because a general preparation sheet says to stop “blood thinners”. Give the clinician your stent details and medicine list so they can obtain specific advice.
Check before adding other medicines
Ask a doctor or pharmacist before using ibuprofen, diclofenac, extra aspirin for pain, herbal products or supplements. They may increase bleeding or affect treatment. Some stomach medicines, including omeprazole and esomeprazole, can interfere with clopidogrel; ask for a review rather than stopping prescribed stomach protection yourself.
Anticoagulants such as apixaban or warfarin work differently from antiplatelets. Do not substitute them for DAPT or add them yourself.
A simple checklist for home
- Know the generic names and schedule of both prescribed medicines.
- Keep an up-to-date prescription and stent discharge summary.
- Set reminders and arrange refills before tablets run out.
- Keep the treating team’s contact details and attend planned follow-up.
- Discuss any change before making it; seek emergency care for warning symptoms.
Regular medicine is part of stent aftercare, even when recovery feels complete.
