It is possible that the increased trembling in your hands, shoulders, and arms after taking the cough syrup is a side effect of the terbutaline component, which can cause nervousness and involuntary shaking.

🩺 Understanding Your Symptoms

• Terbutaline, a bronchodilator in your cough syrup, is known to sometimes cause trembling or shaking as a side effect.
• Since you have had hand tremors for several years that worsened after taking this syrup, the medication may be amplifying your existing symptoms.

⚠️ What You Should Do

• Stop taking the cough syrup and monitor if the trembling decreases.
• Inform your prescribing doctor about your pre-existing tremors and the recent increase after medication.
• Your doctor may consider alternative treatments or evaluate other causes of your tremors.

🩺 When to See a Doctor

• If trembling worsens, spreads, or is accompanied by other symptoms like weakness, difficulty speaking, or coordination problems, seek medical advice promptly.
• A neurologist consultation may be helpful to assess the underlying cause of your long-standing tremors.
