4    CLINICAL PARTICULARS

4.1    Therapeutic indications

A traditional herbal medicinal product used to relieve the symptoms of slightly low mood and mild anxiety, based on traditional use only.

4.2 Posology and method of administration

For oral use only.

Adults and the elderly - Take 1 capsule 3 times daily. Swallow the whole capsule with water.

The use in children or adolescents under 18 years is not recommended (see section 4.4 ‘Special Warnings and Precautions for use’).

Duration of use:

If symptoms worsen, or do not improve after 6 weeks, a doctor or a qualified healthcare practitioner should be consulted.

4.3 Contraindications

Hypersensitivity to St. John’s Wort or to any of the excipients.

Patients with known dermal photosensitivity or those undergoing phototherapy or any photodiagnostic procedures.

Concomitant use with any of the medicines specified in section 4.5. This is because St. John’s wort (Hypericum perforatum) has been shown to induce the cytochrom P450 isoenzymes CYP1A2, CYP2C19, CYP2C9 and CYP3A4 as well as the transport protein P-gycoprotein. This results in pharmacokinetic interaction with a large number of medicines including a possible decrease in the effectiveness of those medicines.

Pharmacodynamic interactions have also been identified with antidepressants, particularly the SSRI antidepressants and the triptan group of medicines

4.4 Special warnings and precautions for use

If the condition worsens, or if symptoms persist for more than 6 weeks a doctor or qualified healthcare practitioner should be consulted.

This product is intended for the relief of symptoms of slightly low mood and mild anxiety. Patients with signs and symptoms of depression should consult a doctor for appropriate treatment.

In very rare cases, particularly in fair-skinned individuals, sunburn type reactions may occur on skin areas exposed to strong sunlight due to photosensitisation by St. John’s wort. Patients taking this product should avoid excessive sunbathing or the use of sunbeds or solariums.

The product should be discontinued at least 10 days prior to elective surgery due to the potential for interactions with medicinal products used during general and regional anaesthesia

The use of this product is not recommended in children and adolescents below the age of 18 years because data are not sufficient and medical advice should be sought.

Do not exceed the stated dose.

4.5 Interaction with other medicinal products and other forms of interaction

Substances in St. John’s wort (Hypericum perforatum) have been shown to induce the cytochrome P450 isoenzymes CYP1A2, CYP2C19, CYP2C9 and CYP3A4 as well as the transport protein P-glycoprotein. This results in pharmacokinetic interactions with a large number of medicines leading to a potential decrease in the effectiveness of those medicines.

The concomitant use of ciclosporin, tacrolimus for systemic use, amprenavir, indinavir and other protease-inhibitors, irinotecan and warfarin is_contraindicated.

Special care should be taken in case of concomitant use of all drug substances the metabolism of which is influenced by CYP1A2, CYP3A4, CYP2C9, CYP2C19 or P-glycoprotein (e.g. amitriptyline, fexofenadine, benzodiazepines, methadone, simvastatin, digoxin, finasteride), because a reduction of plasma concentrations is possible

Users of oral contraceptives taking St. John’s wort (Hypericum perforatum) may experience intracyclic menstrual bleeding and the risk of contraception failure is increased.

Clinically significant pharmacodynamic interactions have also been identified with SSRI antidepressants, and the triptan group of medicines used to treat migraine. Due to the increased risk of undesirable effects associated with these interactions this product should not be used concomitantly with these types of medicines.

This product should not be taken concomitantly with the medicines included in the Table below

If other adverse reactions not mentioned above occur, a doctor, pharmacist or a qualified health care practitioner should be consulted

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continual monitoring of the benefit/risk 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

4.9 Overdose

There is no data on human overdose with St. John’s Wort.

After the intake of up to 4.5g dry extract per day for 2 weeks and additionally 15g dry extract just before hospitalisation seizures and confusion have been reported.

Where a large overdose has occurred, phototoxic reactions may occur. The skin of the patient should be protected for 1-2 weeks from UV irradiation and sunlight. Outdoor activities should be restricted and clothes and/or sun block preparations used to protect the skin from sunlight. Symptomatic and supportive measures should be taken as appropriate.

5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Not required as per Article 16c(1)(a)(iii) of Directive 2001/83/EC as amended.

5.2 Pharmacokinetic properties

Reverse mutation assays (Ames test) on bacteria indicated that the product was mutagenic in Salmonella typhimurium (strains TA 98, TA 100, TA 102, TA 1535 and TA 1537) mutation assays with or without metabolic activation. However, this could be attributed to quercetin/kaempferol and is therefore not considered relevant.

Adequate tests on reproductive toxicity and carcinogenicity have not been performed.
