What Are Sinutab Non-Drowsy Tablets?

 

If you've ever had a cold that leaves your head feeling like it's stuffed with cotton wool, you'll know how miserable sinus congestion can be. Sinutab Non-Drowsy tablets are an over-the-counter medicine designed to tackle exactly that — combining pain relief with a nasal decongestant so you can get on with your day without feeling foggy or sedated. Each pack contains 15 tablets, making it a practical option to keep in your medicine cabinet during cold and flu season. You can browse our full range of cold and flu remedies if you're looking for additional support alongside this product.

Sinutab Non-Drowsy contains two active ingredients: paracetamol 500 mg and pseudoephedrine hydrochloride 30 mg per tablet. Paracetamol is one of the most widely used analgesics and antipyretics in the UK, recommended by the NHS for mild to moderate pain and fever. Pseudoephedrine is a sympathomimetic decongestant that works specifically on the nasal passages. Together, they address the two most common complaints during a cold — the aching head and the blocked nose.

 

How Do Sinutab Non-Drowsy Tablets Work?

 

Understanding how a medicine works helps you use it more confidently. Sinutab Non-Drowsy acts through two distinct mechanisms simultaneously:

  • Paracetamol inhibits the production of prostaglandins in the brain and spinal cord, reducing the perception of pain and lowering elevated body temperature (fever).
  • Pseudoephedrine hydrochloride acts as an alpha-adrenergic agonist, causing vasoconstriction (narrowing of blood vessels) in the nasal mucosa. This reduces swelling and congestion in the sinuses and nasal passages, making it easier to breathe.
  • Because pseudoephedrine is a stimulant rather than a sedating antihistamine, it does not cause the drowsiness associated with older-generation cold remedies — hence the "non-drowsy" formulation.

The NHS notes that decongestants like pseudoephedrine can provide short-term relief from nasal congestion caused by colds, sinusitis, and upper respiratory tract infections. It's worth noting that pseudoephedrine is a regulated substance in the UK — pharmacies are required to keep it behind the counter, and there are legal limits on how much you can purchase at one time.

 

Who Should Use Sinutab Non-Drowsy Tablets?

 

This product is suitable for adults and children aged 12 and over who are experiencing symptoms of a cold, sinusitis, or upper respiratory tract infection. It's particularly useful if you need to remain alert — for example, if you're at work or driving — because it avoids the sedating antihistamines found in some other cold remedies. That said, it's not right for everyone.

Sinutab Non-Drowsy is generally suitable for people who:

  • Have a blocked or stuffy nose alongside a headache or facial pain
  • Are experiencing mild fever associated with a cold or flu
  • Need to stay alert and functional during the day
  • Do not have contraindicated conditions such as hypertension, heart disease, or hyperthyroidism

Is Sinutab Non-Drowsy Suitable for Long-Term Use?

 

Sinutab Non-Drowsy tablets are intended for short-term use only — no more than five consecutive days. Using decongestants for longer than recommended can lead to rebound congestion, where symptoms worsen once you stop the medicine. If your symptoms persist beyond five days, or if they worsen, you should speak to your GP rather than continuing to self-medicate. For those managing ongoing sinus or respiratory issues, it may also be worth exploring our ear, nose and throat range for complementary products.

If you are taking other medicines that contain paracetamol — such as other cold and flu remedies — do not take Sinutab Non-Drowsy at the same time, as this could lead to paracetamol overdose. Always check the ingredients of any other medicines you are using concurrently.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Sinutab Non-Drowsy and What Is It Used For?

 

Sinutab Non-Drowsy 15 Tablets is a combination medicine used to relieve the symptoms of colds, sinusitis, and upper respiratory tract infections. It contains paracetamol 500 mg to ease pain and reduce fever, and pseudoephedrine hydrochloride 30 mg to relieve nasal and sinus congestion. It is classified as a Pharmacy (P) medicine in the UK, meaning it is available without a prescription but must be sold under the supervision of a pharmacist. Sinutab Non-Drowsy tablets are specifically formulated to avoid causing drowsiness, making them suitable for daytime use when you need to remain alert.

 

What Do You Need to Know Before Using Sinutab Non-Drowsy?

 

Before taking this medicine, it is important to check whether it is appropriate for you. Do not take Sinutab Non-Drowsy if any of the following apply:

  • You are allergic to paracetamol, pseudoephedrine, or any other ingredient in the tablets
  • You have high blood pressure (hypertension) or heart disease
  • You have an overactive thyroid (hyperthyroidism)
  • You have diabetes
  • You have glaucoma (raised pressure in the eye)
  • You have difficulty urinating due to an enlarged prostate
  • You are taking or have taken monoamine oxidase inhibitors (MAOIs) within the last 14 days
  • You are pregnant or breastfeeding (seek medical advice first)
  • You are under 12 years of age

The following medicines may interact with Sinutab Non-Drowsy. Tell your pharmacist if you are taking:

  • Other medicines containing paracetamol (risk of overdose)
  • MAOIs or tricyclic antidepressants
  • Other sympathomimetic medicines (e.g. other decongestants, appetite suppressants)
  • Beta-blockers or antihypertensive medicines
  • Warfarin or other anticoagulants (with prolonged paracetamol use)

 

How Should You Use Sinutab Non-Drowsy?

 

Always take this medicine exactly as described in the patient information leaflet or as directed by your pharmacist. Do not exceed the stated dose.

  1. Swallow 2 tablets whole with a glass of water.
  2. Do not crush or chew the tablets.
  3. Leave at least 4 hours between doses.
  4. Do not take more than 4 doses (8 tablets) in any 24-hour period.

What Are the Possible Side Effects of Sinutab Non-Drowsy?

 

Like all medicines, Sinutab Non-Drowsy can cause side effects, although not everyone will experience them. The NHS advises that pseudoephedrine-containing products can cause stimulant-type effects in some people.

Common side effects (may affect up to 1 in 10 people):

  • Difficulty sleeping (insomnia)
  • Increased heart rate (palpitations)
  • Dry mouth
  • Nausea
  • Restlessness or anxiety

Less common side effects (may affect up to 1 in 100 people):

  • Headache
  • Dizziness
  • Urinary retention (difficulty passing urine)
  • Raised blood pressure

Stop taking Sinutab Non-Drowsy and seek immediate medical attention if you experience chest pain, a severe skin reaction (such as blistering or peeling), or signs of a serious allergic reaction (swelling of the face, lips, or throat, difficulty breathing). Paracetamol overdose is a medical emergency — if you think you or someone else has taken too much, go to A&E immediately even if you feel well, as liver damage may not be apparent straight away.

 

How Should You Store Sinutab Non-Drowsy?

 

Correct storage helps maintain the medicine's effectiveness and keeps it safe for use throughout its shelf life.

  • Store below 25°C in a dry place
  • Keep out of direct sunlight and away from moisture
  • Keep all medicines out of the sight and reach of children
  • Do not use after the expiry date printed on the packaging
  • Do not dispose of medicines via wastewater or household waste — return unused medicines to your pharmacy

If you're managing multiple health concerns this winter, it's worth knowing that our vitamins and supplements range includes immune-support options that may help you recover more quickly alongside your cold treatment.

Frequently Asked Questions

Where can I buy Sinutab Non-Drowsy tablets online in the UK?

You can buy Sinutab Non-Drowsy 15 Tablets online from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £5.89. As a Pharmacy (P) medicine, it must be sold under pharmacist supervision, which is why it's available through registered online pharmacies rather than general retailers. You can also find it at some high street pharmacies, though buying online is often more convenient.

How do Sinutab Non-Drowsy tablets work in the body?

Sinutab Non-Drowsy contains paracetamol, which reduces pain signals and lowers fever by inhibiting prostaglandin synthesis in the central nervous system. The pseudoephedrine component acts as a sympathomimetic, causing vasoconstriction in the nasal mucosa to reduce swelling and open up blocked sinuses. Because pseudoephedrine is a stimulant rather than a sedating antihistamine, it does not cause drowsiness — making it suitable for daytime use.

How do I use Sinutab Non-Drowsy step by step?

Take 2 tablets with a full glass of water, swallowing them whole without crushing or chewing. Wait at least 4 hours before taking your next dose, and never exceed 8 tablets (4 doses) in any 24-hour period. Do not take alongside other paracetamol-containing products, and stop after 5 days if symptoms have not improved — then consult your GP.

What is the correct dose of Sinutab Non-Drowsy for adults?

The recommended dose for adults and children aged 12 and over is 2 tablets, taken up to four times a day with at least 4 hours between each dose. The maximum daily dose is 8 tablets (equivalent to 4,000 mg paracetamol and 240 mg pseudoephedrine). Never exceed this dose, as paracetamol overdose can cause serious liver damage even if you feel well initially.

When is the best time to take Sinutab Non-Drowsy?

Because Sinutab Non-Drowsy tablets contain pseudoephedrine — a mild stimulant — it is generally best to take your last dose several hours before bedtime to avoid disrupting your sleep. Taking the first dose in the morning with breakfast can help manage daytime congestion and discomfort effectively. Spacing doses evenly throughout the day (e.g. morning, midday, late afternoon) tends to give the most consistent symptom relief.

What are the side effects of Sinutab Non-Drowsy and how do I manage them?

The most commonly reported side effects include insomnia, increased heart rate, dry mouth, and restlessness — all related to the stimulant action of pseudoephedrine. Taking your last dose well before bedtime and staying well hydrated can help reduce these effects. If you experience chest pain, difficulty breathing, or a severe skin reaction, stop taking the tablets immediately and seek urgent medical attention.

Who is eligible to take Sinutab Non-Drowsy tablets?

Sinutab Non-Drowsy is suitable for adults and young people aged 12 and over who are experiencing nasal congestion, sinus pain, or headache associated with a cold or sinusitis. It is not suitable for children under 12, pregnant or breastfeeding women (without medical advice), or people with high blood pressure, heart disease, hyperthyroidism, glaucoma, or diabetes. Always check with your pharmacist if you are unsure whether this product is right for you.

Can I take Sinutab Non-Drowsy if I have high blood pressure?

No — Sinutab Non-Drowsy is contraindicated in people with hypertension because pseudoephedrine can raise blood pressure by causing vasoconstriction throughout the body, not just in the nasal passages. If you have high blood pressure, speak to your pharmacist or GP before taking any decongestant-containing product. There may be alternative treatments better suited to your situation.

What happens if I miss a dose of Sinutab Non-Drowsy?

If you miss a dose, simply take the next one when it is due — provided at least 4 hours have passed since your last dose. Do not double up to make up for a missed dose, as this could take you over the maximum daily limit of 8 tablets. Sinutab Non-Drowsy is taken as needed for symptom relief rather than on a strict schedule, so missing one dose is unlikely to significantly affect your recovery.

How long can I take Sinutab Non-Drowsy for?

Sinutab Non-Drowsy should not be used for more than 5 consecutive days. Prolonged use of decongestants can lead to rebound congestion (rhinitis medicamentosa), where nasal symptoms worsen once the medicine is stopped. If your cold or sinus symptoms persist beyond 5 days, or if they worsen, you should consult your GP to rule out a bacterial infection or other underlying cause.

Is Sinutab Non-Drowsy safe during pregnancy or breastfeeding?

Sinutab Non-Drowsy is not recommended during pregnancy, particularly in the first trimester, as pseudoephedrine may affect placental blood flow. During breastfeeding, pseudoephedrine can pass into breast milk and may also reduce milk supply. Always consult your GP or midwife before taking any medicine during pregnancy or while breastfeeding — they can advise on the safest options for you and your baby.

Can I take Sinutab Non-Drowsy with other cold and flu medicines?

You should not take Sinutab Non-Drowsy alongside other medicines that contain paracetamol or pseudoephedrine, as this significantly increases the risk of overdose. Many combination cold and flu products — such as Lemsip, Night Nurse, or Day Nurse — already contain paracetamol, so always check the ingredients before combining treatments. If you are unsure, ask your pharmacist before taking more than one cold remedy at a time.

What are the alternatives to Sinutab Non-Drowsy tablets?

If you need a decongestant without pain relief, Sudafed Congestion Relief tablets (pseudoephedrine 60 mg) may be suitable. For those who cannot take pseudoephedrine, xylometazoline nasal sprays offer localised decongestant action with less systemic absorption. You can explore our full cold and flu range to find the most appropriate option for your symptoms.

Can I drive after taking Sinutab Non-Drowsy?

Sinutab Non-Drowsy is formulated to avoid causing drowsiness, so it is generally considered compatible with driving. However, pseudoephedrine can occasionally cause dizziness or restlessness in some individuals, which could affect your ability to drive safely. If you notice any such effects after taking this medicine, do not drive or operate heavy machinery until they have fully resolved.

What does the latest research say about pseudoephedrine for sinus congestion?

Pseudoephedrine remains one of the most clinically studied oral decongestants and is recognised by the NHS as an effective short-term treatment for nasal congestion. Research consistently shows it reduces nasal airway resistance more effectively than placebo when used at recommended doses. It is, however, subject to legal purchase restrictions in the UK due to its potential misuse in the illicit manufacture of controlled substances — which is why it is kept behind the pharmacy counter. For broader respiratory and sinus health support, you may also find our ear, nose and throat collection helpful.

How Should You Use Sinutab Non-Drowsy?

Using Sinutab Non-Drowsy correctly ensures you get the most effective symptom relief while minimising the risk of side effects. Always read the patient information leaflet before taking this medicine, and follow the steps below carefully.

Follow these steps each time you take a dose:

What Is the Correct Dose of Sinutab Non-Drowsy?

The dose varies by age, and it is important not to exceed the maximum daily amount. Taking more than the recommended dose of paracetamol can cause serious liver damage, even if you feel well at the time.

When Is the Best Time to Use Sinutab Non-Drowsy?

Because pseudoephedrine is a mild stimulant, timing your doses thoughtfully can make a real difference to how well you sleep. Take your first dose in the morning to tackle early-day congestion and discomfort, and try to take your last dose of the day at least 4–6 hours before you plan to go to bed. This reduces the likelihood of pseudoephedrine interfering with your sleep, which is already important for recovery when you're unwell.

If you find that symptoms are particularly bad in the morning — as is common with sinusitis — taking a dose shortly after waking with a light breakfast can help you feel more comfortable throughout the day.

How Long Can You Use Sinutab Non-Drowsy For?

Sinutab Non-Drowsy is intended for short-term use only. Do not take it for more than 5 consecutive days. Prolonged use of oral decongestants can lead to rebound congestion, where your nasal passages become more blocked once you stop the medicine than they were before you started. If your symptoms have not improved after 5 days, or if they worsen at any point, stop taking the tablets and consult your GP — a bacterial sinus infection may require antibiotic treatment.

If you are managing a long-term condition affecting your sinuses or airways, speak to your doctor about appropriate ongoing management rather than relying on over-the-counter decongestants.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Sinutab Non-Drowsy?

Most people tolerate Sinutab Non-Drowsy well when taken at the recommended dose, but some individuals do experience side effects — particularly those related to the stimulant action of pseudoephedrine. These effects are generally mild and tend to resolve once you stop taking the medicine.

  • Difficulty sleeping (insomnia)
  • Increased heart rate (palpitations)
  • Dry mouth
  • Nausea
  • Restlessness or feeling anxious

What Are the Less Common Side Effects of Sinutab Non-Drowsy?

Less frequently, some people may notice the following effects. If any of these bother you or persist, speak to your pharmacist or GP for advice.

  • Headache
  • Dizziness
  • Raised blood pressure
  • Difficulty passing urine (urinary retention) — more likely in men with an enlarged prostate
  • Tremor or shakiness

What Are the Serious Side Effects of Sinutab Non-Drowsy?

Serious side effects are rare but require immediate medical attention. Stop taking Sinutab Non-Drowsy straight away and call 999 or go to your nearest A&E if you experience any of the following:

  • Chest pain or a very fast, irregular heartbeat
  • Severe skin reactions such as blistering, peeling, or a widespread rash
  • Signs of a serious allergic reaction (anaphylaxis): swelling of the face, lips, tongue or throat, difficulty breathing, or sudden dizziness
  • Signs of paracetamol overdose: nausea, vomiting, and abdominal pain — seek emergency help immediately even if you feel well, as liver damage may not be apparent for several days

What Should You Do If You Experience Side Effects of Sinutab Non-Drowsy?

For mild side effects such as insomnia or dry mouth, practical steps like taking your last dose earlier in the day and drinking plenty of water can help. If you experience palpitations or feel unusually anxious, stop taking the medicine and speak to your pharmacist — they can advise whether an alternative product without pseudoephedrine would be more suitable for you.

You can also report side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. Reporting side effects helps improve medicine safety information for everyone.

Can Sinutab Non-Drowsy Interact With Other Medicines?

Yes — Sinutab Non-Drowsy has several clinically important interactions that you need to be aware of before taking it. The most serious is with monoamine oxidase inhibitors (MAOIs): taking pseudoephedrine within 14 days of an MAOI can cause a dangerous rise in blood pressure (hypertensive crisis). Other interactions include:

  • Other paracetamol-containing products — risk of accidental overdose
  • Tricyclic antidepressants — may increase cardiovascular side effects
  • Beta-blockers and antihypertensive medicines — pseudoephedrine may reduce their effectiveness
  • Other sympathomimetic medicines (e.g. other decongestants, some appetite suppressants) — additive stimulant effects
  • Warfarin — prolonged use of paracetamol may enhance anticoagulant effect

Always tell your pharmacist about all medicines, supplements, and herbal remedies you are taking before starting Sinutab Non-Drowsy.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
