Dizziness First Aid – What NOT to do

When dealing with dizziness, it is important to avoid actions that could make the situation worse or cause injury. Here are common mistakes and unsafe practices to steer clear of:

Do not ignore severe or sudden dizziness. If dizziness comes on quickly, is intense, or is accompanied by chest pain, difficulty speaking, weakness, or loss of balance, call 911 immediately. These signs may indicate a serious condition such as a stroke or heart problem.
Avoid driving or operating machinery. Dizziness can impair your ability to focus and react quickly. Do not drive, cycle, or use heavy equipment until you feel fully recovered and safe.
Do not stand up too quickly. Sudden movements can worsen dizziness and increase the risk of falling. Instead, rise slowly from sitting or lying down.
Do not consume alcohol or sedatives. These substances can increase dizziness and impair coordination, making falls more likely.
Avoid self-medicating with unprescribed drugs or supplements. Some medications can worsen dizziness or interact with other treatments. Always consult a healthcare provider before taking new medicines.
Do not ignore repeated or worsening symptoms. If dizziness persists, worsens, or is accompanied by other symptoms like vomiting, confusion, or fainting, seek urgent care or visit the emergency department.

Following these guidelines helps ensure safe and effective dizziness first aid. When in doubt, prioritizing professional assessment is the safest choice.
