Giving you your prescribed medicines

If you are prescribed medicines, you will be asked either to collect these from one of our hospital pharmacies or from your GP.

Frequently asked questions

We aim to answer some of your questions you may have about your medicine.

  • How should I store my medicines?

    Medicines should be kept in their original packaging and stored in a cool, dry, dark place out of the sight and reach of children. Some medicines need to be kept in the fridge – this will be clearly marked on the packet or instruction leaflet.

  • What should I do with leftover or expired medicines?

    Make sure that you never take a medicine after its expiry date, which will be printed on the packet. Never throw unused or expired medicines in the rubbish bin or flush them down the toilet. Take unwanted medicines to a pharmacy, where they can be disposed of safely.

  • Is it safe to take herbal medicines?

    Herbal medicines are often thought to be safe as they are ‘natural’. They do however have an effect on the body and can lead to side-effects and so should be used with care. They may also interact with your other medicines, medical conditions, or be unsafe if you are undergoing surgery. Always let your doctor or pharmacist know about any herbal medicines you are taking.

  • What should I do if I have any questions or concerns about my medicines?

    Speak to your pharmacist first. If they can't help or they think that you need to see your doctor, they will advise you to do that. Alternatively, if you are a patient at Guy's and St Thomas’, you can call our pharmacy medicines helpline for advice on 020 7188 8748 (open 9am-5pm Monday to Friday).
