Like all medicines, Lyrica can cause side effects, although not everyone gets them. Understanding the common Lyrica side effects — and the small number of warning signs that need urgent attention — makes it easier to talk to your doctor and to know what is normal when you start treatment. This page is educational information and does not replace the patient leaflet or your prescriber’s advice.
What are the side effects of Lyrica?
Most side effects of Lyrica come from the way it calms nerve activity, which is also why it can make you feel sleepy or unsteady. They tend to be most noticeable when treatment starts or when the dose is increased, and many ease as the body gets used to the medicine. Side effects are usually grouped into common effects, which are fairly frequent but generally mild, and serious effects, which are uncommon but need medical attention.
The pattern is individual: two people on the same dose can have quite different experiences. Keeping a simple note of what you feel and when can help your doctor decide whether to adjust the dose or the timing.
Common side effects of Lyrica
The more common side effects include:
- Dizziness and feeling sleepy or drowsy
- Headache
- Dry mouth and constipation
- Blurred or double vision
- Weight gain and increased appetite
- Swelling (fluid build-up) in the hands, ankles or feet
- Difficulty concentrating or feeling “foggy”
- Feeling unusually relaxed or light-headed
These effects are often mild and temporary. Because dizziness and drowsiness are the most frequent, it is sensible to be careful with driving, alcohol and anything that needs full concentration until you know how Lyrica affects you.
Serious side effects — when to get help
A small number of effects need prompt medical attention. Seek help if you notice:
- Signs of an allergic reaction, such as swelling of the face, lips or throat, or difficulty breathing
- New or worsening low mood, or any thoughts of harming yourself
- A severe or blistering skin rash
- Breathing that becomes slow or shallow, especially in older people or alongside strong painkillers
- Muscle pain, tenderness or weakness, particularly with a fever or feeling unwell
These reactions are uncommon, but knowing them means you can act quickly. Combining Lyrica with opioid painkillers or with alcohol increases the risk of breathing problems, so your prescriber needs to know everything you take.
Lyrica side effects in females
The main side effects of Lyrica are broadly similar for everyone. Some people notice effects such as weight gain, fluid retention or changes in sexual function — including reduced desire or difficulty reaching orgasm — and these can be experienced differently from person to person. None of this is a reason to stop the medicine on your own; if a side effect is affecting your quality of life, your doctor can discuss options.
Lyrica side effects in the elderly
Older adults can be more sensitive to the dizziness and drowsiness Lyrica can cause, which may increase the risk of falls. Kidney function also tends to decline with age, and because pregabalin is cleared by the kidneys, doses are often lower and increased more cautiously in older people. Anyone caring for an older person taking Lyrica should watch for increased confusion or unsteadiness and mention it to the prescriber.
Does Lyrica cause weight gain?
Weight gain and increased appetite are recognised side effects for some people taking Lyrica, and they can be more noticeable at higher doses or with longer-term use. Fluid retention can also add to the effect. If weight change matters to you, our page on Lyrica and weight gain looks at why it happens and what can help.
Do the side effects depend on the dose?
Side effects such as dizziness are more likely as the dose goes up, which is exactly why Lyrica is usually started low and increased step by step. A 75 mg or 150 mg dose is not automatically “worse” than a lower one, but the balance between benefit and side effects shifts as the dose changes. If you feel that side effects outweigh the benefit at your current Lyrica dosage, that is a conversation to have with your prescriber.
How to manage side effects
You can often reduce the impact of side effects by taking Lyrica exactly as prescribed, increasing the dose slowly under medical guidance, staying hydrated, and being cautious with alcohol. Never stop Lyrica abruptly to escape side effects — this can trigger withdrawal symptoms. Instead, tell your doctor, who can adjust the dose or the schedule safely.
