Precautions & warnings

What should I know before using alimemazine tartrate?

Before using this drug, tell your doctor if:

  • You are pregnant or breastfeeding. This is because, while you are expecting or feeding a baby, you should only take medicines on the recommendation of a doctor.
  • You are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • You have allergy with any of active or inactive ingredients of alimemazine tartrate or other medications.
  • You have any other illnesses, disorders, or medical conditions.

Alimemazine may cause drowsiness, dizziness and blurred vision. If affected do not drive or operate machinery. If children are affected they should avoid potentially hazardous activities such as riding bikes or climbing trees.

Do not drink alcohol while taking alimemazine as this is likely to make any drowsiness or dizziness worse.

Alimemazine may make you feel dizzy or light-headed when getting up from sitting or lying down. Take care when getting up, particularly if you wake up in the night, until you know how this medicine affects you. If you feel dizzy or light-headed at any time during treatment, sit or lie down until the symptoms pass.

Alimemazine may increase the sensitivity of your skin to sunlight and might make it more likely to burn. If you can’t avoid sun exposure you should make sure you protect your skin with clothing or sun protection lotion.

If you’re due to have any skin prick or patch tests to diagnose allergies, you should stop taking your antihistamines at least 48 hours before the tests. This is because antihistamines can prevent or reduce the skin reactions that indicate an allergy, and so can make the test results unreliable.

Patients with these following should not use this drug:

  • People with kidney or liver problems.
  • People with epilepsy.
  • People with Parkinson’s disease.
  • People with an underactive thyroid gland (hypothyroidism).
  • People with a tumour of the adrenal gland (phaeochromocytoma).
