Do not take with a cough suppressant.


If any of the following occur, this medicine should be stopped



Sleep disturbances

Caution in moderate to severe renal impairment.

Pseudoephedrine should be used with caution when administered to patients taking antihypertensive agents, tricyclic antidepressants, other sympathomimetic agents such as decongestants, appetite suppressants and amphetamine-like psycho-stimulants. The effects of a single dose on the blood pressure of these patients should be observed before recommending repeated or unsupervised treatment.

Severe Skin reactions

Severe skin reactions such as acute generalized exanthematous pustulosis (AGEP) may occur with pseudoephedrine-containing products. This acute pustular eruption may occur within the first 2 days of treatment, with fever, and numerous, small, mostly non-follicular pustules arising on a widespread oedematous erythema and mainly localized on the skin folds, trunk, and upper extremities. Patients should be carefully monitored. If signs and symptoms such as pyrexia, erythema, or many small pustules are observed, administration of Boots Cough and Decongestant Syrup 6 Years + should be discontinued and appropriate measures taken if needed.

Ischaemic colitis

Some cases of ischaemic colitis have been reported with pseudoephedrine. Pseudoephedrine should be discontinued and medical advice sought if sudden abdominal pain, rectal bleeding or other symptoms of ischaemic colitis develop

Ischaemic optic neuropathy

Cases of ischaemic optic neuropathy have been reported with pseudoephedrine.

Pseudoephedrine should be discontinued if sudden loss of vision or decreased visual acuity such as scotoma occurs.

Do not give with any other cough and cold medicine.

If symptoms do not go away, talk to your pharmacist or doctor.

4.5 Interaction with other medicinal products and other forms of interaction


MAOIs and/or RIMAs: should not be given to patients treated with MAOIs or within 14 days of stopping treatment: increased risk of hypertensive crisis.

Moclobemide: risk of hypertensive crisis.

Antihypertensives: (including adrenergic neurone blockers, diuretics & beta-blockers): pseudoephedrine may block the hypotensive effects.

Cardiac glycosides: increased risk of dysrhythmias.

Ergot alkaloids (ergotamine & methysergide): increased risk of ergotism.

Appetite suppressants and amphetamine-like psycho-stimulants: risk of hypertension.

Oxytocin: risk of hypertension.

Enhances effects of anticholinergic drugs (such as TCAs).

Should not be given with other sympathomimetics such as decongestants, and thyroid hormones. Should not be given to patients undergoing general anaesthesia as them may induce ventricular arrhythmias.


If urine is collected within 24 hours of a dose of guaifenesin a metabolite of guaifenesin may cause a colour interference with laboratory determinations of urinary 5-hydroxyindoleacetic acid (5-HIAA) and vanillylmandelic acid (VMA).

4.6 Fertility, pregnancy and lactation


There are limited amount of data on the use of pseudoephedrine in pregnant women. The use of pseudoephedrine during the first trimester of pregnancy has been associated with an increased frequency of gastroschisis (a development defect in the abdominal wall with intestinal herniation) and of small intestinal atresia (congenital obstruction of small intestine). Due to the vasoconstrictive properties of pseudoephedrine, it may induce a reduction in uteroplacental circulation.

Pseudoephedrine is not recommended in pregnancy.


Pseudoephedrine has been detected in human milk with a small percentage of the maternal dose potentially administered to the breastfed infant. Irritability and disturbed sleep have been reported in breastfed infants. Pseudoephedrine may suppress lactation. Avoid if lactation not well established or if milk production is insufficient.

The amounts of guaifenesin secreted into breast milk are considered too small to be harmful.

4.7 Effects on ability to drive and use machines

No adverse effects known.

4.8 Undesirable effects


The following side effects may be associated with the use of guaifenesin:

Gastrointestinal disorders: nausea, vomiting, gastrointestinal discomfort.

Immune system disorders: hypersensitivity reactions.


Cardiovascular disorders: tachycardia, palpitations, other cardiac dysrythmias.

Eye disorders: Frequency unknown - Ischaemic optic neuropathy

Gastrointestinal disorders: nausea and/or vomiting, dry mouth.

Frequency unknown: Ischaemic colitis

General disorders and administration site conditions: irritability, thirst, tolerance with dependence has been reported with prolonged administration of pseudoephedrine-containing preparations.

Immune system disorders: hypersensitivity reactions, including cross-sensitivity that may occur with other sympathomimetics.

Musculoskeletal and connective tissue disorders: muscular weakness.

Nervous system disorders: headache, giddiness, tremor, anxiety, restlessness, excitability, insomnia, hallucinations (particularly in children) and paranoid delusions.

Psychiatric disorders: sleep disturbance.

Renal and urinary disorders: difficulty in micturition including urinary retention.

Skin and subcutaneous tissue disorders: skin reactions including rash, sweating. Frequency unknown - Severe skin reactions, including acute generalized exanthematous pustulosis (AGEP).

Vascular disorders: hypertension.

Reporting of suspected adverse reactions

Reporting 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: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Symptoms of overdosage include headache, nausea, vomiting, tachycardia, urinary retention, hallucinations, coma, tremor, excitement, convulsions, respiratory depression, hypertension and arrhythmias.

Initial treatment consists of either emesis or gastric lavage, if appropriate. Otherwise treatment should be symptomatic and supportive, including the administration of a beta blocker if supraventricular tachycardia supervenes.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pseudoephedrine acts directly on both alpha and to a lesser extent beta adrenergic receptors. It is believed that the alpha adrenergic effects result from inhibition of the production of cyclic AMP by inhibition of the enzyme adenyl cyclase, whereas beta adrenergic effects result from stimulation of adenyl cyclase activity. Pseudoephedrine also has an indirect effect by releasing noradrenaline from its storage sites.

Guaifenesin reduces the viscosity of tenacious sputum and is used as an expectorant.

5.2 Pharmacokinetic properties

Pseudoephedrine is absorbed from the gastrointestinal tract. It is resistant to metabolism by monoamine oxidase and is largely excreted unchanged in the urine together with small amounts of its hepatic metabolite. It has an elimination half-life of several hours.

Guaifenesin is readily absorbed from the gastrointestinal tract. It is metabolised and excreted in the urine.
