What Are The Side Effects Of Antihistamines?

Dizziness

When dizzy, individuals might have trouble keeping their balance, and they might feel like the ground is moving under their feet. They might experience nausea, tinnitus, and stumbling. If the dizziness is serious enough, some patients even fall over or faint. Dizziness can be a side effect of antihistamines, but it can also be caused by the allergies antihistamines are treating. When dizziness is related to the allergies themselves, it's because sinus congestion has become serious enough to affect the inner ear. Antihistamines are more likely to contribute to dizziness if patients take them with certain substances. Because antihistamines increase drowsiness, patients are likely to experience greater drowsiness and dizziness if they take them alongside alcohol, sleeping pills, muscle relaxants, anti-anxiety medications, or antidepressants. If patients are not sure what medications are safe to take with their allergy medication, they should ask their doctor or pharmacist. If every antihistamine they try causes dizziness, patients might need to treat their allergies with something else.
