Sedating antihistamine / antivertigo / antiemetic

Typical grounding period: 48 hours (2 days)

Measured from the last dose, and only once completely side-effect free.

Guidance notes

Sedating antihistamines and phenothiazine antiemetics impair alertness, vision and vestibular function for many hours after the last dose. Not acceptable for flying duty. The underlying vertigo, nausea or motion-sickness problem must itself be cleared by a DAME before return to duty.
