Shared care policies are developed when sophisticated or complex treatments that were initiated in secondary care are then prescribed by a GP. They set out the process that needs to be followed for the GP to take on prescribing responsibility. The term 'Effective Shared Care Agreement' (ESCA) is now being used. ESCAs should be patient specific and encompass all aspects relevant to that particular patient.
Clinical responsibility should be considered for transfer to primary care only where it is agreed that the patient's clinical condition is stable or predictable.

Other Information

- A single dose of pneumococcal polysaccharide vaccine and annual influenza vaccine should be given.
- Tacrolimus capsules should be swallowed whole with plenty fluid, preferably on an empty stomach at least one hour before or 2-3 hours after a meal.
- There are a number of drug interactions that must be considered when a new drug is prescribed. Please referto Summary of Product Characteristics, BNF, or contact Medicines Information.
- Do not give with ciclosporin due to increased risk of nephrotoxicity.
- Grapefruit and grapefruit juice should not be taken at the same time as tacrolimus.
- Potassium sparing diuretics and potassium salts should be used with caution due to the risk of hyperkalaemia.
- Significantly increased tacrolimus blood levels have been noted with the following drugs that inhibit CYP3A4 – ketoconazole, fluconazole, intraconazole, voriconazole, erythromycin and HIV Protease inhibitors. Caution also advised with weaker CYP3A4 inhibitors eg omeprazole and nifedipine.
- Inducers of CYP3A4 shown to decrease the blood levels of tacrolimus include rifampicin, phenytoin, phenobarbitone and St John’s Wort.
- Methylprednisolone has been reported to increase ordecrease tacrolimus plasma levels.
- Enhanced nephrotoxicity has been observed following the administration of either of the following drugs in conjunction with tacrolimus – amphotericin B or ibuprofen.
- As tacrolimus may alter the metabolism of steroid based contraceptive agents, particular care should be exercised when deciding upon contraceptive measures. Non-hormonal contraceptives should be used.
Discuss with consultant. Effective contraception is required during treatment. Tacrolimus capsules alter the metabolism of oral contraceptives, so non-hormonal methods should be used. Advise the patient to contact their physician immediately should pregnancy occur.
Breast Feeding
Discuss with Aberdeen Maternity Hospital. Manufacturer advises avoid.
Responsibilities of GPs
A GP should:
- Contact a consultant or registrar in the Renal Unit in the event of a drug reaction or monitoring abnormality or anything you are unhappy about.
- Only continue to prescribe tacrolimusif it is being satisfactorily monitored.
