What Are Muscle Twitches?
Muscle twitching is when muscles contract involuntarily. Also called muscle fasciculation, twitches can occur on any part of the body. Most of the time twitches are harmless, but in some cases, they may be a sign of a problem with the nervous system.
Unlike tics, which are usually repetitive with numerous continuous occurrences of the same action, muscle twitches are isolated occurrences, and not repeated actions.
What Causes Twitches?
Causes of muscle twitches that usually go away on their own include:
- Consumption of caffeine or other stimulants
- Stress or anxiety (“nervous ticks”)
- Lack of sleep
- Nicotine from smoking and tobacco use
- Eye irritation or dryness (eyelid twitching)
- Physical activity due to accumulation of lactic acid (lactic acidosis) or electrolyte deficiency
- Nutrient deficiencies such as vitamin D, vitamin B, and calcium
- Dehydration
- Side effects of medications such as corticosteroids, estrogen pills, diuretics, antidepressants, some seizure medications, and certain drugs used to treat psychosis
Serious causes of muscle twitches include:
- Bell's palsy
- Multiple sclerosis
- Tourette's syndrome
- Muscular dystrophy
- Amyotrophic lateral sclerosis (ALS, also called Lou Gehrig’s disease)
- Spinal muscular atrophy
- Kidney disease
- Neuropathy (nerve damage)
- Isaac’s syndrome

What Is the Treatment for Twitches?
For less serious and often temporary causes of muscle twitching, no treatment may be needed and twitching will usually go away on its own. If treatment is needed, it may include:
- Consumption of caffeine or other stimulants
- Reduce or avoid caffeine or stimulant use
- Stress or anxiety (“nervous ticks”)
- Practice stress reduction techniques such as mediation, deep breathing, or yoga
- Lack of sleep
- Try to maintain good hygiene and get adequate sleep
- Nicotine from smoking and tobacco use
- Don’t smoke or use tobacco
- Eye irritation or dryness (eyelid twitching)
- If there is no underlying medical condition causing eye irritation or dryness, lubricating eye drops may help
- Physical activity due
- Accumulation of lactic acid (lactic acidosis)
- Reduce intensity or duration of exercise
- Get adequate fluid intake
- Rest
- Electrolyte deficiency
- Drink enough water while exercising
- Consume coconut water or sports drinks with electrolytes
- Accumulation of lactic acid (lactic acidosis)
- Nutrient deficiencies such as vitamin D, vitamin B, and calcium
- Dehydration
- Increase water intake
- Side effects of medications such as corticosteroids, estrogen pills, diuretics, antidepressants, some seizure medications, and certain drugs used to treat psychosis
- Talk to your doctor about changing to another medication that may not cause the side effects
- Do not stop taking any medications without first talking to your doctor
For more serious and chronic causes of muscle twitching, treatment involves addressing the underlying cause:
- Bell's palsy
- Steroids
- Antiviral agents, in addition to steroids
- Pain relievers such as aspirin, acetaminophen, or ibuprofen
- Eye protection, including lubricating eye drops, such as artificial tears or eye ointments or gels, and eye patches
- Physical therapy
- Facial massage
- Acupuncture
- Decompression surgery (controversial and not often recommended)
- Multiple sclerosis
- Medications to reduce the severity and frequency of relapses
- High dose corticosteroids for attacks
- Rehabilitation for fitness and energy levels
- Tourette's syndrome
- Neuroleptic medications such as haloperidol and pimozide
- Alpha-adrenergic agonists such as clonidine and guanfacine
- Stimulants such as methylphenidate and dextroamphetamine to reduce ADHD symptoms
- Serotonin reuptake inhibitors (SSRIs) such as clomipramine, fluoxetine, fluvoxamine, paroxetine, and sertraline for obsessive-compulsive symptoms
- Muscular dystrophy
- Amyotrophic lateral sclerosis (ALS, also called Lou Gehrig’s disease)
- Medications such as riluzole (Rilutek) and edaravone (Radicava)
- Physical therapy and special equipment
- Speech therapy
- Nutritional support
- Breathing support
- Spinal muscular atrophy
- Physical therapy
- Assistive equipment to increase mobility, such as leg braces, walkers, and wheelchairs
- Back braces to assist sitting and prevent scoliosis
- Breathing exercises, cough machines, and chest physiotherapy
- Medications: nusinersen (Spinraza)
- Kidney disease
- Medications to treat high blood pressure such as ACE inhibitors, angiotensin receptor blockers (ARBs)
- Diet low in sodium, protein, potassium, and phosphate
- Dialysis
- Kidney transplant
- Neuropathy (nerve damage)
- Healthy lifestyle habits such as maintaining an optimal weight, eating a balanced diet, and correcting vitamin deficiencies
- Quit smoking
- Exercise regularly
- Control blood sugar (in patients with diabetes)
- Immunosuppressive drugs such as prednisone, cyclosporine, or azathioprine

- Local anesthetics and narcotics (opioids) for pain that doesn’t respond to other pain-control medications
- Surgery for some types of neuropathies such as disk problems in the back or trigeminal neuralgia on the face
- Transcutaneous electrical nerve stimulation (TENS)
