Sinuend combines paracetamol 200 mg, caffeine 20 mg and ephedrine 6 mg. It relieves sinus and cold symptoms — headache, facial pain and a blocked nose — by pairing a painkiller with a decongestant. It raises blood pressure, so it is unsuitable for some people.
What is Sinuend?
Sinuend contains three active ingredients:
- Paracetamol 200 mg — for pain and fever
- Caffeine 20 mg — a mild stimulant that enhances paracetamol
- Ephedrine 6 mg — a decongestant
Each targets a different part of the problem. Paracetamol relieves the headache and facial pain. Ephedrine narrows the swollen blood vessels lining the nose and sinuses, reducing congestion and opening the airway. Caffeine modestly increases paracetamol’s pain-relieving effect and offsets some of the fatigue of a cold.
Ephedrine is the ingredient that determines who should not take this. It is a sympathomimetic — it acts on the same receptors as adrenaline. That is how it shrinks swollen nasal tissue, and it is also why it raises blood pressure and heart rate, and can cause restlessness, palpitations and insomnia.
Note the paracetamol amount: 200 mg is well below a standard 500 mg dose, so this product is not primarily a painkiller. Its main purpose is the decongestant, with paracetamol supporting it.
What is Sinuend commonly used for?
- Sinus congestion and sinus headache.
- Facial pain and pressure from blocked sinuses.
- Nasal congestion from a cold.
- Cold and flu symptoms generally.
- Hay fever congestion, though an antihistamine or steroid nasal spray suits allergy better.
It does not treat the cause. Colds are viral and resolve on their own — typically within a week to ten days. Most sinus congestion following a cold is also viral and settles without antibiotics.
Sinusitis needing antibiotics is less common than people assume. Symptoms that persist beyond about ten days, or that improve and then clearly worsen, or that come with a high fever and severe one-sided facial pain, are the ones worth having assessed. Before that point, decongestion and time are the treatment.
Steam, saline rinses and staying upright genuinely help sinus congestion, and a saline nasal rinse in particular is effective, cheap and has none of the cautions below.
For allergic congestion, a steroid nasal spray works considerably better and can be used long term, which a decongestant cannot.
How Sinuend fits into this medicine category
| Type | Examples | Note |
|---|---|---|
| Painkiller + decongestant | Sinuend, Sinustat | For sinus pain with congestion |
| Multi-symptom cold products | Flustat | Also cover cough |
| Plain paracetamol | Donapan, Zypol | Pain and fever alone |
| Decongestant nasal sprays | Oxymetazoline | Fast local relief; rebound with overuse |
| Steroid nasal sprays | Fluticasone | Best for allergic congestion; long-term use |

What to check before using Sinuend
Do not take it if you have high blood pressure or heart disease without asking first. This is the central check. Ephedrine raises blood pressure and heart rate, and decongestant-free alternatives exist for exactly this reason.
Do not take any other paracetamol product alongside it — including plain paracetamol, other cold remedies, or compound painkillers such as Mybulen. Even though Sinuend contains only 200 mg, doubling up still counts toward your daily maximum.
Do not take it late in the evening. Both ephedrine and caffeine can prevent sleep.
Speak to a pharmacist or doctor if:
- You have high blood pressure, heart disease, or an irregular heartbeat.
- You have an overactive thyroid.
- You have diabetes — ephedrine can affect blood sugar.
- You have glaucoma, particularly narrow-angle.
- You have an enlarged prostate or difficulty passing urine.
- You take an MAOI antidepressant, or have in the past two weeks. This combination can cause a dangerous rise in blood pressure.
- You take another decongestant, a medicine for blood pressure, or a beta blocker.
- You have liver disease, or drink alcohol heavily.
- You are pregnant or breastfeeding.
- The medicine is for a child. Decongestant-containing products are not recommended for young children.
- You are sensitive to caffeine.
Follow the pack instructions and the maximum in 24 hours.
Possible cautions and when to ask a pharmacist or doctor
Use it for a few days, not weeks. Decongestants are short-term medicines. If congestion persists beyond about a week, the cause needs identifying rather than continued treatment.
Do not confuse it with a decongestant nasal spray. Sprays such as oxymetazoline work quickly but cause rebound congestion if used beyond about five days, leaving the nose more blocked than before. That specific trap applies to sprays rather than tablets, but people frequently use both together.
Expect possible restlessness, palpitations or difficulty sleeping from the ephedrine and caffeine.
Paracetamol overdose is a medical emergency with no early warning. If too much has been taken across several products, go to an emergency department immediately with the packaging, even if the person feels well.
Saline rinses and steam are worth trying properly — they reduce how much medicine you need.
See a doctor if symptoms last beyond ten days, if they improve and then clearly worsen, if you have a high fever, severe one-sided facial pain, swelling around the eye, or visual changes. Swelling or redness around the eye with a sinus infection needs urgent assessment.
Seek urgent medical attention for chest pain, palpitations, a severe headache unlike your usual one, visual disturbance, confusion, one-sided weakness or slurred speech, difficulty breathing, or a rash with facial swelling.

Frequently asked questions
What is Sinuend used for? Sinus and cold symptoms — headache, facial pain and pressure, and a blocked nose. It contains paracetamol, caffeine and ephedrine.
Can I take it if I have high blood pressure? Ask a pharmacist first. Ephedrine raises blood pressure and heart rate, and a decongestant-free alternative is usually better.
Does it treat a sinus infection? No. It relieves symptoms. Most sinus congestion after a cold is viral and settles on its own; antibiotics are needed less often than people assume.
Why does it keep me awake? It contains both ephedrine and caffeine, which are stimulating. Avoid taking a dose late in the evening.
Can I take paracetamol with it? It already contains paracetamol, so count it toward your daily maximum and do not double up with another product.
What else helps a blocked nose? Saline nasal rinses, steam and staying upright genuinely help, and have none of the cautions of a decongestant.
