10 Reasons Your Hands Might Be Shaking

4. Medication or Drug-Induced Tremor

Many medications list tremors or shaking as potential side effects. While these tremors often fall into other classifications, medical experts find it helpful to also view them as a unique category. Drugs for conditions like asthma often increase stress hormone levels, which can trigger a tremor. Antidepressants that stimulate serotonin receptors can also be responsible. A tremor is probably a side-effect of medication if it stays consistent, looks the same on both sides, or only occurs after changing dosages.
