How is Antihistamine administered?
Antihistamines can be administered orally, parenterally (intravenous or intramuscular injection), or rectally. The specific administration method depends on the form of the medicine and the patient's needs.
For oral administration: Take antihistamines with food or a glass of water or milk to lessen stomach irritation if necessary. Swallow extended-release tablets whole, without breaking, crushing, or chewing.
For parenteral administration: If you will be giving yourself the injection, make sure you understand exactly how to do it and follow your healthcare professional's instructions.
For rectal administration: To insert the suppository, remove the foil wrapper and moisten it with cold water. Lie down on your side and use your finger to push the suppository well up into the rectum. If the suppository is too soft to insert, chill it in the refrigerator for 30 minutes or run cold water over it before removing the foil wrapper.
Always follow your healthcare professional's instructions and the specific dosing information provided on the label or prescription for the most suitable administration route for your condition.
