Fertility, pregnancy and breast-feeding This medicine belongs to a group of medicines which may affect fertility in women. Fertility goes back to normal when you stop taking the medicine. It is unlikely that if you only take Nurofen Sinus & Blocked Nose 200 mg/5 mg Tablets occasionally it will affect your chances of becoming pregnant. If you have problems becoming pregnant talk to your doctor before taking this medicine. Tell your doctor if you become pregnant whilst taking this medicine. Do not take this medicine if you are in the last 3 months of pregnancy as it could harm your unborn child or cause problems at delivery. It can cause kidney and heart problems in your unborn baby. It may affect your and your baby's tendency to bleed and cause labour to be later or longer than expected. You should not take this medicine during the first 6 months of pregnancy unless absolutely necessary and advised by your doctor. If you need treatment during this period
or while you are trying to get pregnant, the lowest dose for the shortest time possible should be used. If taken for more than a few days from 20 weeks of pregnancy onward, this medicine can cause kidney problems in your unborn baby that may lead to low levels of amniotic fluid that surrounds the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the heart of the baby. If you need treatment for longer than a few days, your doctor may recommend additional monitoring. Avoid the use of this medicine in the first 6 months of pregnancy unless the doctor advises otherwise. Speak to your doctor or pharmacist before taking this medicine if you are breast-feeding. This medicine contains Sunset Yellow E 110. The product contains an azo colouring agent Sunset Yellow E 110 which may cause allergic reactions. This medicine contains less than 1mmol sodium (23 mg) per 2 tablets, that is to say essentially `sodium-free'.

Nurofen Sinus & Blocked Nose 200mg/5mg Tablets comes as tablet containing 200mg / 5mg. Always follow the dose your doctor or pharmacist has given you, and read the leaflet that comes with the medicine.
The active substance in Nurofen Sinus & Blocked Nose 200mg/5mg Tablets is ibuprofen, phenylephrine hydrochloride.
Medicines with the same active substance, strength and form include: Nurofen Cold & Flu Relief 200mg/5mg Tablets, Nurofen Day & Night Cold & Flu 200mg/5mg Tablets. They are interchangeable only if your prescriber or pharmacist says so.
This leaflet reproduces the patient information leaflet approved for Nurofen Sinus & Blocked Nose 200mg/5mg Tablets, as published on the electronic medicines compendium (emc). The version printed inside your medicine’s packaging is the one that applies to you.
Whether a medicine is available over the counter or on prescription only depends on its licence. Check the leaflet, or ask your pharmacist — they can tell you straight away.
The text above reproduces the patient information leaflet approved for this medicine, restructured for easier reading.
For the relief of symptoms of cold and 'flu with associated congestion, including aches and pains, headache, fever, sore throat, blocked nose and sinuses.
For oral administration and short-term use only.
The lowest effective dose should be used for the shortest duration necessary to relieve symptoms (see section 4.4).
Adults, the elderly and children over 12 years:
The patient should consult a doctor if symptoms persist or worsen, or if the product is required for more than 10 days.
Two tablets up to 3 times a day. Leave at least four hours between doses and do not take more than 6 tablets in any 24hour period.
Not to be given to children under 12 years.
Hypersensitivity to ibuprofen, phenylephrine or any of the excipients in the product.
Hypertension and severe coronary heart disease.
Patients who have previously shown hypersensitivity reactions (e.g. asthma, rhinitis, angioedema or urticaria) in response to aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs).
Active or history of recurrent peptic ulcer/haemorrhage (two or more distinct episodes or proven ulceration or bleeding).
History of gastrointestinal bleeding or perforation, related to previous NSAIDs therapy.
Severe heart failure (NYHA Class IV), renal failure or hepatic failure (see section 4.4).
Last trimester of pregnancy.
Use with concomitant NSAIDs including cyclo-oxygenase-2 specific inhibitors (see Section 4.5).
Hyperthyroidism.
Contraindicated in patients currently receiving or within two weeks of stopping therapy with monoamine oxidase inhibitors.
Avoid in patients with prostatic enlargement.
Phaeochromocytoma: Phenylephrine should not be used in patients with phaeochromocytoma.
Ibuprofen
Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see gastrointestinal and cardiovascular risks below).
The elderly are at increased risk of consequence of adverse reactions to NSAIDs, especially gastrointestinal bleeding and perforation which may be fatal.
Respiratory: Bronchospasm may be precipitated in patients suffering from or with a previous history of bronchial asthma or allergic disease.
Other NSAIDs: The use of this product with concomitant NSAIDs, including cyclo-oxygenase-2 selective inhibitors, should be avoided (see section 4.5).
SLE and mixed connective tissue disease: Systemic lupus erythematosus and mixed connective tissue disease - increased risk of aseptic meningitis (see section 4.8).
Renal: Renal impairment as renal function may further deteriorate, especially in dehydrated children and adolescents (see sections 4.3 and 4.8).
Renal tubular acidosis and hypokalaemia may occur following acute overdose and in patients taking ibuprofen products over long periods at high doses (typically greater than 4 weeks), including doses exceeding the recommended daily dose.
Hepatic: Hepatic dysfunction (see sections 4.3 and 4.8).
Cardiovascular and cerebrovascular effects: Caution (discussion with doctor or pharmacist) is required prior to starting treatment in patients with a history of hypertension and/or heart failure as fluid retention, hypertension and oedema have been reported in association with NSAID therapy.
Clinical studies suggest that use of ibuprofen, particularly at a high dose (2400 mg/day) may be associated with a small increased risk of arterial thrombotic events (for example, myocardial infarction or stroke). Overall, epidemiological studies do not suggest that low dose ibuprofen (≤1200 mg/day) is associated with an increased risk of arterial thrombotic events.
Patients with uncontrolled hypertension, congestive heart failure (NYHA II-III), established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated with ibuprofen after careful consideration and high doses (2400 mg/day) should be avoided.
Careful consideration should also be exercised before initiating long-term treatment of patients with risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking), particularly if high doses of ibuprofen (2400 mg/day) are required.
Impaired female fertility: There is limited evidence that drugs which inhibit cyclo-oxygenase/prostaglandin synthesis may cause impairment of female fertility by an effect on ovulation. This is reversible on withdrawal of treatment.
Gastrointestinal: NSAIDs should be given with care to patients with a history of gastrointestinal disease (ulcerative colitis, Crohn's disease) as these conditions may be exacerbated (see section 4.8).
GI bleeding, ulceration or perforation, which can be fatal, has been reported with all NSAIDs at any time during treatment, with or without warning symptoms or a previous history of serious GI events.
The risk of GI bleeding, ulceration or perforation is higher with increasing NSAID doses, in patients with a history of ulcer, particularly if complicated with haemorrhage or perforation (see section 4.3), and in the elderly. These patients should commence treatment on the lowest dose available.
Patients with a history of GI toxicity, particularly the elderly, should report any unusual abdominal symptoms (especially GI bleeding), particularly in the initial stages of treatment.
Caution should be advised in patients receiving concomitant medications which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or antiplatelets agents such as aspirin (see Section 4.5).
When GI bleeding or ulceration occurs in patients receiving ibuprofen, the treatment should be withdrawn.
Severe skin reactions:
Serious skin reactions, some of them fatal, including exfoliating dermatitis, Stevens-Johnson Syndrome, and toxic epidermal necrolysis, have been reported very rarely in association with the use of NSAIDs (see Section 4.8).
Patients appear to be at highest risk of these reactions early in the course of therapy: the onset of the reaction occurring in the majority of cases within the first month of treatment. Acute generalised exanthematous pustulosis (AGEP) has been reported in relation to ibuprofen-containing products. This product should be discontinued at the first appearance of signs and symptoms of severe skin reactions, such as skin rash, mucosal lesions or any other sign of hypersensitivity.
Masking of symptoms of underlying infections:
This medicinal product can mask symptoms of infection, which may lead to delayed initiation of appropriate treatment and thereby worsening the outcome of the infection. This has been observed in bacterial community acquired pneumonia and bacterial complications to varicella. When this medicine is administered for fever or pain relief in relation to infection, monitoring of infection is advised. In non-hospital settings, the patient should consult a doctor if symptoms persist or worsen.
The label will include:
Read the enclosed leaflet before taking this product.
Do not take if you:
• Have (or have had two or more episodes of) a stomach ulcer, perforation or bleeding.
• Are allergic to ibuprofen or any other ingredient of the product, aspirin or other related painkillers.
• Are taking other NSAID painkillers, other products containing phenylephrine or aspirin with a daily dose above 75 mg.
• Are in the last 3 months of pregnancy
Speak to a pharmacist or your doctor before taking if you:
• Have or have had asthma, diabetes, high cholesterol, high blood pressure, a stroke, heart, liver, kidney or bowel problems.
• Are a smoker.
• Are pregnant.
If symptoms persist or worsen, consult your doctor.
Phenylephrine
Phenylephrine should be used with care in patients with cardiovascular disease, diabetes mellitus, closed angle glaucoma, Raynaud's Phenomenon and hypertension.
The product contains an azo colouring agent Sunset Yellow E 110 which may cause allergic reactions.
This medicine contains less than 1 mmol sodium (23 mg) per 2 tablets, that is to say essentially `sodium-free'.
Ibuprofen
Ibuprofen should not be used in combination with:
Aspirin (acetylsalicylic acid): Concomitant administration of ibuprofen and acetylsalicylic acid is not generally recommended because of the potential of increased adverse effects, unless low-dose aspirin (not above 75 mg daily) has been advised by a doctor (see Section 4.4).
Experimental data suggest that ibuprofen may competitively inhibit the effect of low dose aspirin (acetylsalicylic acid) on platelet aggregation when they are dosed concomitantly. Although there are uncertainties regarding extrapolation of these data to the clinical situation, the possibility that regular, long-term use of ibuprofen may reduce the cardioprotective effect of low-dose acetylsalicylic acid cannot be excluded. No clinically relevant effect is considered to be likely for the occasional ibuprofen use (see section 5.1).
Other NSAIDs including cyclo-oxygenase-2 selective inhibitors: Avoid concomitant use of two or more NSAIDs as this may increase the risk of adverse reactions (see section 4.4).
Ibuprofen should be used with caution in combination with:
Anti-coagulants: NSAIDs may enhance the effects of anticoagulants such as warfarin (see Section 4.4).
Antihypertensives and diuretics: NSAIDs may diminish the effect of these drugs.
Diuretics can increase the risk of nephrotoxicity.
Corticosteroids: Increased risk of gastrointestinal ulceration or bleeding (see section 4.4).
Anti-platelet agents and selective serotonin-reuptake inhibitors (SSRIs): Increased risk of gastrointestinal bleeding (see section 4.4).
Cardiac glycosides: NSAIDs may exacerbate cardiac failure, reduce GFR and increase plasma glycoside levels.
Lithium: There is evidence for potential increase in plasma levels of lithium.
Methotrexate: There is potential for an increase in plasma methotrexate.
Ciclosporin: Increased risk of nephrotoxicity.
Mifepristone: NSAIDs should not be used for 8-12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone.
Tacrolimus: Possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus.
Zidovudine: Increased risk of haematological toxicity when NSAIDs are given with zidovudine. There is evidence of an increased risk of haemarthroses and haematoma in HIV(+) haemophiliacs receiving concurrent treatment with zidovudine and ibuprofen.
Quinolone antibiotics: Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.
Phenylephrine
Monoamine oxidase inhibitors (including moclobemide): hypertensive interactions occur between sympathomimetic amines such as phenylephrine and monoamine oxidase inhibitors (see section 4.3).
Sympathomimetic amines: concomitant use of phenylephrine with other sympathomimetic amines can increase the risk of cardiovascular side effects.
Beta-blockers and other antihypertensives (including debrisoquine, guanethidine, reserpine, methyldopa): phenylephrine may reduce the efficacy of beta-blockers and antihypertensives. The risk of hypertension and other cardiovascular side effects may be increased (see section 4.3).
Tricyclic antidepressants (e.g. amitriptyline): may increase the risk of cardiovascular side effects with phenylephrine (see section 4.3).
Digoxin and cardiac glycosides: concomitant use of phenylephrine may increase the risk of irregular heartbeat or heart attack.
Ibuprofen
Whilst no teratogenic effects have been demonstrated in animal experiments, the use of this product should, if possible, be avoided during the first six months of pregnancy.
From the 20th week of pregnancy onward, ibuprofen use may cause oligohydramnios resulting from foetal renal dysfunction. This may occur shortly after treatment initiation and is usually reversible upon discontinuation. In addition, there have been reports of ductus arteriosus constriction following treatment in the second trimester, most of which resolved after treatment cessation. Therefore, during the first and second trimester of pregnancy, Ibuprofen should not be given unless clearly necessary. If ibuprofen is used by a woman attempting to conceive, or during the first and second trimester of pregnancy, the dose should be kept as low and duration of treatment as short as possible. Antenatal monitoring for oligohydramnios and ductus arteriosus constriction should be considered after exposure to Ibuprofen for several days from gestational week 20 onward. Ibuprofen should be discontinued if oligohydramnios or ductus arteriosus constriction are found.
During the third trimester, ibuprofen is contraindicated as there is a risk of premature constriction/closure of the fetal ductus arteriosus with possible persistent pulmonary hypertension. The onset of labour may be delayed and the duration increased with an increased bleeding tendency in both mother and child (see section 4.3).
In limited studies, ibuprofen appears in the breast milk in very low concentrations and is unlikely to affect the breast-fed infant adversely.
See section 4.4 regarding female fertility.
Phenylephrine
The safety of this medicine during pregnancy and lactation has not been established but in view of a possible association of foetal abnormalities with first trimester exposure to phenylephrine, the use of the product during pregnancy should be avoided. In addition, because phenylephrine may reduce placental perfusion, the product should not be used in patients with a history of preeclampsia. In view of the lack of data on the use of phenylephrine during lactation, this medicine should not be used during breast feeding.
No adverse effects known

Description of Selected Adverse Reactions
1 Examples include anaemia, leucopenia, thrombocytopenia, pancytopenia and agranulocytosis. First signs are fever, sore throat, superficial mouth ulcers, flu-like symptoms, severe exhaustion, unexplained bleeding and bruising.
2 Hypersensitivity reactions have been reported following treatment with ibuprofen and these may consist of: (a) Non-specific allergic reaction and anaphylaxis. (b) Respiratory tract reactivity, e.g. asthma, aggravated asthma, bronchospasm or dyspnoea. (c) Various skin reactions, e.g. pruritus, urticaria, angioedema and, more rarely, exfoliative and bullous dermatoses (including epidermal necrolysis and erythema multiforme).
3 The pathogenic mechanism of drug-induced aseptic meningitis is not fully understood. However, the available data on NSAID-related aseptic meningitis points to a hypersensitivity reaction (due to a temporal relationship with drug intake, and disappearance of symptoms after drug discontinuation). Of note, single cases of symptoms of aseptic meningitis (such as stiff neck, headache, nausea, vomiting, fever or disorientation) have been observed during treatment with Ibuprofen in patients with existing auto-immune disorders (such as systemic lupus erythematosus and mixed connective tissue disease).
4Clinical studies suggest that use of ibuprofen, particularly at a high dose (2400 mg/day) may be associated with a small increased risk of arterial thrombotic events (for example, myocardial infarction or stroke) (see Section 4.4).
5 The most commonly-observed adverse events are gastrointestinal in nature.
6 Sometimes fatal, particularly in the elderly.
7 See section 4.4.
8 Especially in long-term use, associated with increased serum urea and oedema. Also includes papillary necrosis.
*Renal tubular acidosis and hypokalaemia have been reported in the post-marketing setting typically following prolonged use of the ibuprofen component at higher than recommended doses.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Ibuprofen
In children, ingestion of more than 400 mg/kg may cause symptoms. In adults, the dose response rate effect is less clear cut. The half-life in overdose is 1.5-3 hours.
Symptoms
Patients who have ingested clinically important amounts of NSAIDs will develop no more than nausea, vomiting, epigastric pain, or more rarely diarrhoea.
Tinnitus, headache and gastrointestinal bleeding are also possible. In more serious poisoning, toxicity is seen in the central nervous system, manifesting as drowsiness, occasionally excitation and disorientation or coma. Occasionally patients develop convulsions. In serious poisoning metabolic acidosis may occur and prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur. Exacerbation of asthma is possible in asthmatics.
In serious poisoning metabolic acidosis may occur and the prothrombin time/INR may be prolonged, probably due to interference with the actions of circulating clotting factors. Acute renal failure and liver damage may occur.
Prolonged use at higher than recommended doses may result in severe hypokalaemia and renal tubular acidosis. Symptoms may include reduced level of consciousness and generalised weakness (see section 4.4 and section 4.8).
Management
Management should be symptomatic and supportive and include the maintenance of a clear airway and monitoring of cardiac and vital signs until stable. Consider oral administration of activated charcoal if the patient presents within 1 hour of ingestion of a potentially toxic amount. If frequent or prolonged, convulsions should be treated with intravenous diazepam or lorazepam. Give bronchodilators for asthma.
Phenylephrine
Features of severe overdose of phenylephrine include haemodynamic changes and cardiovascular collapse with respiratory depression.
Treatment includes early gastric lavage and symptomatic and supportive measures. Hypertensive effects may be treated with an intravenous alpha-receptor blocking agent.
Phenylephrine overdose is likely to result in: nervousness, headache, dizziness, insomnia, increased blood pressure, nausea, vomiting, mydriasis, acute angle closure glaucoma (most likely to occur in those with closed angle glaucoma), tachycardia, palpitations, allergic reactions (e.g. rash, urticaria, allergic dermatitis), dysuria, urinary retention (most likely to occur in those with bladder outlet obstruction, such as prostatic hypertrophy).
Additional symptoms may include hypertension, and possibly reflex bradycardia.
In severe cases confusion, hallucinations, seizures and arrhythmias may occur.
Treatment should be as clinically appropriate. Severe hypertension may need to be treated with alpha blocking medicinal products such as phentolamine.
