Which medication or medication class does NOT have dizziness or vertigo as potential adverse side effects?

Meclizine, commonly known as Antivert, is indeed used to treat and prevent dizziness and vertigo associated with motion sickness and balance disorders. It works by blocking certain signals in the brain that trigger these sensations, which means it is more likely to cause drowsiness or sedation rather than being free from dizziness as a potential adverse effect.

Conversely, gentamicin and streptomycin are aminoglycoside antibiotics that can cause vestibular toxicity, leading to dizziness and vertigo. These adverse effects are quite significant due to the ototoxic potential of these medications, which can affect balance.

High-dose salicylates, such as aspirin, can also result in tinnitus and hearing disturbances, which may manifest as dizziness or vertigo, particularly at higher doses.

Understanding the side effect profiles of these medications is crucial, as it reflects their pharmacological mechanisms and potential toxicities, ensuring safe prescribing practices and effective patient management in clinical settings.
