For a full list of excipients, see section 6.1.

3 PHARMACEUTICAL FORM

Tablet.

Round coated tablet, light green-coloured.

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 short term use only.

Adults and the elderly: Take one tablet daily.

Swallow the tablet whole with a little liquid. Do not chew the tablet.

The patient should consult a doctor or qualified healthcare practitioner if symptoms worsen or do not improve after 6 weeks.

Children and adolescents less than 18 years old: This product is not indicated in patients less than 18 years. See section 4.4. special warnings and precautions for use

4.3 Contraindications

Hypersensitivity to the active ingredient or any of the excipients.

This product should not be taken concomitantly with any of the medicines included in Section 4.5. This is because St John’s wort (Hypericumperforatum) has been shown to induce the cytochrome P450 isoenzymes CYP1A2, CYP2C9, CYP2C19 and CYP3A4 as well as transport protein P-glycoprotein. This results in pharmacokinetic interactions with a large number of medicines including leading to a possible decrease in the effectiveness of those medicines.

In addition, pharmacodynamic interactions have also been identified with antidepressants, particularly the SSRI antidepressants and with the triptan group of medicines.

4.4 Special warnings and precautions for use

Do not exceed the recommended dose.

If symptoms worsen or do not improve after six weeks medical advice should be sought.

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

This product is intended for relief of symptoms of slightly low mood and mild anxiety. Patients with signs and symptoms of depression should seek medical advice for appropriate treatment.

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

This 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 (see Section 4.5).

Patients with rare hereditary problems of fructose intolerance, glucosegalactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

4.5 Interaction with other medicinal products and other forms of interaction

Substances in St John’s wort (Hypericumperforatum) have been shown to induce the cytochrome P450 isoenzymes CYP1A2, CYP2C9, CYP2C19 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 concentration is possible.

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

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

Therefore this product should not be taken concomitantly with the medicines included in Table below:

5    PHARMACOLOGICAL PROPERTIES

5.1    Pharmacodynamic properties

The active constituents of St. John’s wort have not been established definitely. However, hypericin, pseudohypericin, hyperforin and the flavonoids are considered to play a role in its activity.

5.2 Pharmacokinetic properties

No definitive pharmacokinetic data are available

The active ingredients of St John’s wort can interact with other medicinal agents in two ways. Firstly, active ingredients in St John’s wort that themselves are metabolised in the liver by the CYP3A4 isoenzyme, increase (induce) the activity of this enzyme so that it accelerates the elimination of other medicinal agents which are degraded by the same pathway. This leads to a consequent reduction in the plasma concentration and effectiveness of these other substances. Secondly, the active ingredients in St John’s wort, like other type SRI or SSRI medicinal agents with an antidepressant action, can raise the concentration of serotonin in certain parts of the central nervous system so that this neurotransmitter can sometimes reach toxic levels, particularly when drugs containing St John’s wort are combined with other antidepressants.

5.3 Preclinical safety data

Tests on reproductive toxicity, genotoxicity and carcinogenicity have not been performed.
