PRECAUTIONS

- [RENAL INSUFFICIENCY]. Accumulation of dimenhydrinate may occur, because it and its metabolites are excreted in the urine.
- [LIVER FAILURE]. Dimenhydrinate accumulation may occur due to its high hepatic metabolism.

- [EPILEPSY]. Antihistamines have occasionally been associated with paradoxical hyperexcitability reactions.
- [APENDICITIS]. Due to its antiemetic effects, it could delay the diagnosis of appendicitis.
- Ototoxicity. Dimenhydrinate may ameliorate vertigo, tinnitus, and dizziness, thus it may mask ototoxicity induced by ototoxic drugs.
- Photosensitivity. Dimenhydrinate could lead to photosensitivity phenomena, so it is recommended not to sunbathe during treatment, and protect yourself with sun filters.
- Extreme temperatures. It could aggravate heat stroke due to decreased sweating caused by its anticholinergic effects. It is recommended to avoid exposure to very high temperatures and to follow adequate hygienic-dietary measures, such as adequate aeration and hydration.

INTERACTIONS
