Résumé
Pregabalin is widely used to treat neuropathic pain associated with postherpetic neuralgia. To our knowledge, this is the first report on simultaneously occurring dose-related adverse drug reactions (ADRs) of balance disorder, asthenia, peripheral edema, and constipation in an elderly patient after pregabalin. A 76-year-old female with a history of postherpetic neuralgia was prescribed pregabalin (300 mg daily). After taking pregabalin for 7 d, the patient developed balance disorder, weakness, peripheral pitting edema (2+), and constipation. On days 8-14, the pregabalin dose was reduced to 150 mg/d based on creatinine clearance. The patient's peripheral edema improved significantly with the disappearance of all other adverse symptoms. On day 15, the pregabalin dose was increased to 225 mg/d to relieve pain. Unfortunately, the symptoms mentioned earlier gradually reappeared after 1 wk of pregabalin treatment. However, the complaints were not as severe as when taking 300 mg/d pregabalin. The patient consulted her pharmacist by telephone and was advised to reduce the dose of pregabalin to 150 mg/d and add acetaminophen (0.5 g, q6h) to relieve pain. The patient's ADRs gradually improved over the following week. Older patients should be prescribed a lower initial dose of pregabalin. The dose should be titrated to the maximum tolerable dose to avoid dose-limiting ADR. Dose reduction and the addition of acetaminophen may help limit ADR and improve pain control.

BACKGROUND
BACKGROUND
Pregabalin is widely used to treat neuropathic pain associated with postherpetic neuralgia. To our knowledge, this is the first report on simultaneously occurring dose-related adverse drug reactions (ADRs) of balance disorder, asthenia, peripheral edema, and constipation in an elderly patient after pregabalin.
CASE SUMMARY
METHODS
A 76-year-old female with a history of postherpetic neuralgia was prescribed pregabalin (300 mg daily). After taking pregabalin for 7 d, the patient developed balance disorder, weakness, peripheral pitting edema (2+), and constipation. On days 8-14, the pregabalin dose was reduced to 150 mg/d based on creatinine clearance. The patient's peripheral edema improved significantly with the disappearance of all other adverse symptoms. On day 15, the pregabalin dose was increased to 225 mg/d to relieve pain. Unfortunately, the symptoms mentioned earlier gradually reappeared after 1 wk of pregabalin treatment. However, the complaints were not as severe as when taking 300 mg/d pregabalin. The patient consulted her pharmacist by telephone and was advised to reduce the dose of pregabalin to 150 mg/d and add acetaminophen (0.5 g, q6h) to relieve pain. The patient's ADRs gradually improved over the following week.
CONCLUSION
CONCLUSIONS
Older patients should be prescribed a lower initial dose of pregabalin. The dose should be titrated to the maximum tolerable dose to avoid dose-limiting ADR. Dose reduction and the addition of acetaminophen may help limit ADR and improve pain control.
