What is Lyrica for
Lyrica (or pregabalin, which is its active principle) is a drug that exerts its action on the central nervous system, reducing the excitability of neurons to certain stimuli. Thanks to this action, Lyrica is usually indicated as an anticonvulsant in patients suffering from epilepsy , and as an analgesic in patients suffering from neuropathic pain (caused by nerve damage) such as those caused by diabetes or herpes zoster . One of its main indications also includes generalized anxiety disorders , which is characterized by excessive and prolonged worries.
However, the drug became popular to treat diseases for which its use was not approved by the relevant institutions because they believe that while Lyrica can alleviate the symptoms of these conditions, the risks often outweigh the benefit of its use. Some of these uses are as follows:
- Fibromyalgia (approved for use in the United States, but not in Europe)
- Lumbar pain
- Prevention of postoperative pain
- Migraine prevention
- Restless Leg Syndrome
- Essential tremor
- Hot flushes
In some situations the use of Lyrica for these conditions is reasonable, but they should never be considered first-line drugs; its use is reserved for when other medications are contraindicated or ineffective.
Recommended doses of Lyrica
In cases of epilepsy, neuropathic pain and generalized anxiety, its intake can generally vary between 150, 300 and 600 milligrams per day , depending on the results obtained and the patient’s tolerance . The dose should always be adjusted to each patient.
It is not necessary to make a dose modification of Lyrica for patients with hepatic impairment, but on the other hand, the dose must be adjusted in patients with renal impairment.
Contraindications to the use of Lyrica
- If the patient has hypersensitivity (allergic reaction) to the use of Lyrica, its use should be avoided.
- As there is not much evidence on the excretion of Lyrica in breast milk and its effects on a nursing baby or growing fetus, its use by women during lactation and pregnancy should be avoided .
- It should be handled with care in patients with heart problems or suicidal tendencies , as the use of Lyrica can aggravate these situations.
