From the Guidelines
The starting dose of Lyrica (pregabalin) is typically 50 mg three times daily or 75 mg twice daily, with a gradual increase based on individual response and tolerability, usually after 3-7 days, up to a maximum of 300-600 mg per day divided into two or three doses. When considering the starting dose of Lyrica, it's essential to take into account the patient's kidney function, as dose adjustments are necessary for those with reduced kidney function 1. The dose can be increased based on individual response and tolerability, and common side effects include dizziness, drowsiness, dry mouth, and weight gain. Some studies suggest that a lower starting dose may be appropriate for elderly patients or those with kidney impairment, such as 50 mg three times daily or 75 mg once daily 1. However, the most recent and highest quality study recommends a starting dose of 50-75 mg twice or three times daily, with a gradual increase up to a maximum of 600 mg per day 1. It's crucial to assess kidney function before starting treatment and to monitor for potential side effects, as Lyrica works by binding to calcium channels in the nervous system, reducing the release of excitatory neurotransmitters that are involved in pain, seizures, and anxiety. Key points to consider when prescribing Lyrica include:
- Starting dose: 50-75 mg twice or three times daily
- Gradual increase: based on individual response and tolerability, usually after 3-7 days
- Maximum dose: 300-600 mg per day divided into two or three doses
- Kidney function: assess before starting treatment and monitor for potential side effects
- Common side effects: dizziness, drowsiness, dry mouth, and weight gain.

From the Research
Starting Dose of Lyrica
- The starting dose of Lyrica (pregabalin) varies depending on the condition being treated and the patient's renal function 3, 4.
- For patients with neuropathic pain, the recommended starting dose is 150 mg per day, which can be increased to 300 mg per day after 1 week 3.
- In patients undergoing hemodialysis, the starting dose is 25 mg, which can be increased up to a maximum of 150 mg depending on the patient's response 4.
- It is essential to adjust the dose according to the patient's renal function to minimize the risk of adverse events 5, 6.
Dose Adjustment
- The dose of Lyrica should be adjusted based on the patient's renal function, with lower doses recommended for patients with impaired renal function 5, 6.
- In patients with acute renal failure, the dose of Lyrica should be reduced or discontinued to prevent adverse events such as myoclonus and encephalopathy 6.
Adverse Events
- Common adverse events associated with Lyrica include somnolence, dizziness, and peripheral edema 3, 7.
- The risk of adverse events increases with higher doses of Lyrica, and patients should be monitored closely for signs of adverse events 7.
- In some cases, Lyrica can cause serious adverse events such as seizures, which can occur when the drug is suddenly discontinued or in patients with impaired renal function 5.
