Lyrica Side Effects | Risks, Warnings, and Safety Information

Last Edited: April 17, 2026

Living with chronic nerve pain can significantly affect daily life, especially with conditions like diabetic neuropathy or fibromyalgia. Pregabalin, commonly known as Lyrica (including Lyrica CR), is prescribed to manage several types of nerve-related pain. While treatment can be effective, understanding Lyrica side effects is an important part of making informed decisions about care. Side effects can vary based on dosage, age, and individual health factors, which is why learning what to expect—and when to ask questions—can be helpful as you continue reading.

What is Lyrica?

Lyrica, also known by its generic name pregabalin, is a prescription medicine used to treat various conditions such as nerve pain, fibromyalgia, and epilepsy. It works by calming the overactive nerves in the brain that are responsible for causing pain or seizures. Lyrica is also used to treat epilepsy by managing seizures and reducing abnormal electrical activity in the brain. Lyrica is often prescribed for patients experiencing neuropathic pain resulting from diabetes, shingles, or spinal cord injuries. It can also be effective in managing partial-onset seizures when used alongside other medications. The drug is available in pregabalin oral forms such as capsules and solutions, and is typically taken two to three times daily, with or without food. Side effects may include dizziness, sleepiness, dry mouth, swelling, and blurred vision. Due to its potential for causing dependency, Lyrica should be taken strictly as prescribed by a healthcare provider.

Composition of Lyrica

Lyrica (pregabalin) is primarily composed of the active ingredient pregabalin. In addition to the active ingredient, the capsules contain several inactive ingredients that serve various purposes, such as aiding in the manufacturing process, preserving the stability of the medication, and ensuring proper absorption in the body. The inactive ingredients in Lyrica capsules typically include:

Lactose Monohydrate: Acts as a filler to give the capsule its bulk.
Corn Starch: Used as a filler and to help with the consistency of the capsule.
Talc: Serves as an anti-caking agent to prevent the ingredients from clumping together.
Gelatin: Forms the capsule shell.
Titanium Dioxide: Used as a pigment to give the capsule its white color.
Sodium Lauryl Sulfate: Helps the gelatin dissolve in the stomach.
FD&C Yellow No. 6 and FD&C Red No. 40: Used as colorants in some capsule formulations.

The exact composition may vary slightly depending on the specific dosage form and manufacturer, but these ingredients are commonly found in Lyrica capsules.

Lyrica Imprints

Lyrica (pregabalin) capsules have distinctive imprints that vary depending on the dosage strength of the medication. These imprints help in identifying the specific dosage and ensure that patients receive the correct medication. Here are the common imprints found on Lyrica capsules:

Lyrica 25 mg: Imprinted with “Pfizer” on one side and “PGN 25” on the other.
Lyrica 50 mg: Imprinted with “Pfizer” on one side and “PGN 50” on the other.
Lyrica 75 mg: Imprinted with “Pfizer” on one side and “PGN 75” on the other.
Lyrica 100 mg: Imprinted with “Pfizer” on one side and “PGN 100” on the other.
Lyrica 150 mg: Imprinted with “Pfizer” on one side and “PGN 150” on the other.
Lyrica 200 mg: Imprinted with “Pfizer” on one side and “PGN 200” on the other.
Lyrica 225 mg: Imprinted with “Pfizer” on one side and “PGN 225” on the other.
Lyrica 300 mg: Imprinted with “Pfizer” on one side and “PGN 300” on the other.

These imprints are designed to be easy to read and recognize, providing a straightforward way to confirm the medication’s dosage and authenticity.
