Encyclopedia > Muscle twitching
Name of Symptom/Sign: Fasciculation
ICD-10 code: R25.3
ICD-9 code: 781.0

A fasciculation (or "muscle twitching") is a small, local, involuntary muscle contraction (twitching) visible under the skin arising from the spontaneous discharge of a bundle of skeletal muscle fibres. Fasciculations have a variety of cause, the majority of which are benign. The term symptom (from the Greek syn = con/plus and pipto = fall, together meaning co-exist) has two similar meanings in the context of physical and mental health: A symptom may loosely be said to be a physical condition which shows that one has a particular illness or disorder (see...

Medications

Other risk factors may include the use of anticholinergic drugs over long periods—in particular, ethanolamines such as Benadryl, used as an antihistamine and sleep aid, and Dramamine for nausea and motion sickness. Persons with BFS may experience paraesthesia shortly after taking such medication, then hours later as it wears off (especially upon awaking), fasciculation episodes begin.

Stimulants can cause fasciculations directly. These include caffeine, pseudoephedrine (Sudafed®), and albuterol/salbutamol (Proventil®, Combivent®, Ventolin®). Stimulant medications used to treat attention deficit disorder often contain stimulants as well, and are common causes of benign fasciculations. Caffeine molecular structure Anhydrous (dry) USP grade Caffeine Caffeine, also known as trimethylxanthine, coffeine, theine, mateine, guaranine, methyltheobromine and 1,3,7-trimethylxanthine, is a xanthine alkaloid found naturally in such foods as coffee beans, tea, kola nuts, Yerba mate, guarana berries, and (in small amounts) cacao beans. ... Pseudoephedrine is a sympathomimetic amine commonly used as a decongestant. ... Salbutamol (INN) or albuterol (USAN) is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and COPD. It is marketed by the Allen & Hanburys respiratory division of GlaxoSmithKline under the trade name Ventolin. ...

Treatment

Inadequate magnesium intake can cause fasciculations, especially after a magnesium loss due to severe diarrhea. Over-exertion is another risk factor for magnesium loss. As many as 80% of the population does not get the recommended daily amount of magnesium, this may be a common cause. Treatment is with supplements or increased intake of foods rich in magnesium, especially almonds and other nuts, and bananas. Ironically, magnesium supplements may result in diarrhea and more magnesium loss.

Muscle twitching (fasciculation) is the result of spontaneous local muscle contractions that are involuntary and typically only affect individual muscle groups connected to (innervated by) a particular motor neuron.
Ordinary muscle cramps are common and may be stopped by stretching the affected muscle.
