Editorial team. Drug-induced tremor. Drugs that can cause tremor include the following: Cancer medicines such as thalidomide and cytarabine Seizure medicines such as valproic acid Depakote and sodium valproate Depakene Asthma medicines such as theophylline and albuterol Immune suppressing medicines such as cyclosporine and tacrolimus Mood stabilizers such as lithium carbonate Stimulants such as caffeine and amphetamines Antidepressant drugs such as selective serotonin reuptake inhibitors SSRIs and tricyclics Heart medicines such as amiodarone, procainamide, and others Certain antibiotics Certain antivirals, such as acyclovir and vidarabine Alcohol Nicotine Certain high blood pressure drugs Epinephrine and norepinephrine Weight loss medicine tiratricol Too much thyroid medicine levothyroxine Tetrabenazine, a medicine to treat excessive movement disorder.

The shaking is usually fast, about 4 to 12 movements per second. The tremor may be: Episodic occurring in bursts, sometimes about an hour after taking the medicine Intermittent comes and goes with activity, but not always Sporadic happens on occasion The tremor can: Occur either with movement or at rest Disappear during sleep Get worse with voluntary movement and emotional stress Other symptoms may include: Head nodding Shaking or quivering sound to the voice.

Other drugs used to treat asthma are Muscaranic agonists like Ipratropium , Xanthines like Theophylline , also Glucorticoids like Beclomethasone , Prednisolone and Hydrocortisone. Sodium Cromolyn a mast cell stabiliser and inhibits hyper-responsivity is also used to treat asthma [5].

The tremor is dose-related, and the theory of why it causes the tremor is still unexplained. However, the initial understanding suggests that the B2 adrenoreceptor agonist salbutamol has a direct effect on the muscles active state this ' leads to incomplete fusion and reduced tension of tetanic contractions.

More recently, tremor has been correlated closely with hypokalaemia [6]. Increased pulse and tolerance are the main side effects of using salbutamol. In another series of measurements, reproducibility and reference values of the tremor was assessed in 65 healthy subjects in three sessions, at 9 a.

Postural tremor was measured with the arm horizontally outstretched rest tremor with the arm supported by an armrest and finally tremor was measured after holding a 2-kg weight until exhaustion. Inter-observer variability was measured in a series of 10 healthy subjects. Tremor was measured simultaneously by two independent observers.
