2. What you need to know before taking Normostop

Do not take Normostop

  • If you are allergic to dimenhidrinato or difenhidramina or any of the other components of this medicine (listed in section 6).
  • If you have porphyria (a rare, usually inherited disorder in which large amounts of porphyrin are eliminated in urine and feces).

Warnings and precautions

Consult your doctor or pharmacist before starting to take Normostop:

  • If you are allergic to any allergy medication, you may also be allergic to dimenhidrinato.
  • If you have asthma or severe respiratory diseases (chronic obstructive pulmonary disease, emphysema, chronic bronchitis), as it may cause thickening of secretions and alter expectoration.
  • If you have a disease that causes abnormal increased activity of the thyroid gland (hyperthyroidism), increased intraocular pressure (glaucoma), enlarged prostate (prostatic hypertrophy), or any disease that causes obstruction of the urinary or gastrointestinal tract.
  • If you have seizures with convulsive movements, with or without loss of consciousness (epilepsy).
  • If you are over 65 years old, dry mouth, urinary retention, nausea, sedation, confusion, and low blood pressure (hypotension) may occur.
  • If you are taking any medication that can cause ear toxicity, as symptoms of these toxic effects, such as ringing in the ears, dizziness, or vertigo, may be masked.
  • If you have any liver or kidney disease, stomach or duodenal ulcer, or stomach inflammation (gastritis).
  • If you have or have had heart diseases or disorders (cardiac arrhythmia, myocardial ischemia, ...).
  • If you suspect you may have symptoms of appendicitis, such as nausea, vomiting, or abdominal cramps, it is recommended to consult a doctor to rule out the presence or absence of appendicitis, as dimenhidrinato may hinder the diagnosis of this disease.
  • It is recommended to avoid exposure to very high temperatures and follow adequate hygiene and dietary measures, such as proper ventilation and hydration.
  • Avoid exposure to the sun (even on cloudy days) and UV lamps while taking this medication.
