Experimenting with dosages
Since the expense of over-the-counter newer antihistamines has dropped, some patients are experimenting with dosages on their own. If the dose of loratadine (Claritin) or cetirizine (Zyrtec) of one 10 mg tablet per day is not providing good relief for nasal allergies, would two or three tablets be worth trying?
- The fact that a medication is readily available should not suggest patients should be experimenting with it.
- The fact that a medication is not expensive should not suggest that taking more than the recommended dosage is a good or safe idea.
- The dosing of an antihistamine for one condition (like hives) should not suggest that taking more than the recommended dosage for a different condition (like nasal allergies) is a good or safe idea.
- With regard to cetirizine, studies have clearly identified that there is a dose relationship problem with sedation. The higher the dose, the more the sedation. Sedation includes both sleepiness (somnolence) and brain impairment (like memory, judgment, learning). Even 10 mg/day is associated with sedation greater than placebo (a sugar pill).
- There is no reliable data that proves that 20 or 30 mg/day of loratadine or cetirizine will provide greater relief of nasal allergies than 10 mg/day.
- Therefore, if an adolescent or adult patient with nasal allergies symptoms is not adequately controlled by well tolerated loratadine or cetirizine 10mg/day, further evaluating the cause of the symptoms, recommending alternative medications or adding a second pharmacological substance from a different class of agents would all be more appropriate treatment options than increasing the dose of loratadine or cetirizine.
