Medical disclaimer

GLP Index is a price database and a plain English guide to published UK rules. Nothing on the site is medical advice.

• GLP Index does not prescribe, sell or supply medicine.
• Prices and rules pages are for information only. They do not replace a consultation.
• Rules pages summarise the MHRA, NICE, the NHS and the GPhC, with a link to each source. The original source always takes priority over our summary.
• Rules pages are compiled by GLP Index. They are not written or reviewed by a clinician.
• A UK prescriber decides whether a treatment and a dose suit you.
• For a health question, speak to your GP, a pharmacist or NHS 111. In an emergency call 999.
• Report a suspected side effect to the MHRA through the Yellow Card scheme.
