The Renal Drug Handbook suggests the following doses:

GFR 10 to 20ml/minute: no dosage adjustment necessary but avoid if possible.
GFR less than 10ml/minute: Dose as in normal renal function but only if on dialysis.
Patients with Hepatic Impairment
An initial daily dose of 100 mg should be used in patients with hepatic impairment.

The importance of prostaglandins in maintaining renal blood flow should be taken into account in patients with impaired cardiac or renal functions, those being treated with diuretics or recovering from major surgery. Effects on renal function are usually reversible when treatment is withdrawn.
If abnormal liver function tests persist or worsen, clinical signs and symptoms consistent with liver disease develop or if other manifestations occur (eosinophilia, rash), treatment should be discontinued. Hepatitis may occur without prodromal symptoms.
Patients with a history of peptic ulcers, particularly those with haemorrhaging or perforation, are at a higher risk of GI bleeding, ulceration or perforation with increasing doses of NSAIDs. The lowest available dose should be administered initially; a protective agent (misoprostol/proton pump inhibitor) should be considered for concomitant therapy. Patients requiring low dose aspirin should also be considered for concomitant therapy along with other drugs that may increase gastrointestinal risk.
Pregnancy and Lactation
Aceclofenac is contraindicated during the 3rd trimester of pregnancy but may be used with caution in the 1st and 2nd trimester.
The manufacturer does not recommend aceclofenac during pregnancy.
When an NSAID is considered essential in the first and second trimester, a more established drug such as ibuprofen may be considered (Schaefer, 2015).
Studies in animals have shown an increased pre- and post-implantation loss and embryo-foetal lethality when a prostaglandin synthesis inhibitor has been administered. Additionally, increased incidences of malformations, including cardiovascular, has been observed when a prostaglandin synthesis inhibitor is given during the organogenetic period.
Aceclofenac may have the following effects during the third trimester:
- Pulmonary and cardiac toxicity in the foetus/newborn (pulmonary hypertension and premature closure of the ductus arteriosus).
- Renal dysfunction in the foetus, which may progress to renal failure with oligo-hydroamniosis.
- Inhibition of uterine contractions with delayed onset and prolongation of labour.
- Increased possibility of bleeding in mother and neonate at the end of pregnancy.
Use aceclofenac with caution during breastfeeding.
In limited studies so far available, NSAIDs can appear in breast milk in very low concentrations. The manufacturer recommends avoiding the use of aceclofenac unless the potential benefits to the mother outweigh the possible risks to the foetus.
When an NSAID is considered necessary during breastfeeding ibuprofen or flurbiprofen would be the drugs of choice (Briggs, 2015).
