Prescribing for patients with Renal Disease

 

Many drugs prescribed by dentists are excreted by the kidney.

Failure to excrete a drug or its metabolites may lead to toxicity.

As a general rule any drug that is nephrotoxic (such as gentamicin which may be used in prophylaxis against endocarditis) should be avoided. Other drugs may require dose reduction.

Erythromycin is contraindicated in patients who have had a kidney transplant and are taking cyclosporin. Cyclosporin metabolism is reduced leading to an increase in toxicity.

 

Drugs contained in the Dental Practitioners Formulary whose dose should be reduced in the presence of significant kidney disease include the antimicrobials acyclovir, amoxicillin, ampicillin, cefalexin and erythromycin. Tetracyclines other than doxicycline should be avoided.

Non-steroidal analgesics should not be prescribed in those with more than mild renal impairment, paracetomol being the drug of choice for post-operative pain control.

Drugs used in dental sedation should be used with extreme care as a greater effect than normal may be produced.
