Cyproheptadine belongs to a group of medicines known as sedating antihistamines. It is used to relieve allergies, such as hay fever and some allergic skin conditions. You can buy cyproheptadine tablets without a prescription at a pharmacy.

Exposure to substances such as pollen, pet fur, house dust or insect bites can cause some people to produce an excess of a chemical called histamine. This causes allergic symptoms which can include skin rashes, sneezing, watery eyes, and a runny or blocked nose. Because cyproheptadine blocks the effects of histamine, it helps relieve allergic symptoms like these.

Before taking cyproheptadine

To make sure that this is the right treatment for you, before you start taking cyproheptadine it is important that you discuss the treatment with a doctor or pharmacist if:

  • Estás embarazada, esperando un bebé o dando el pecho.

  • Tiene algún problema con el funcionamiento del hígado o con los riñones.

  • Padece una enfermedad que aumenta la presión ocular, como el glaucoma.

  • Si tiene problemas de próstata o si ha tenido dificultades para orinar.

  • You know you have a stomach ulcer or a blockage in your small intestines.

  • Tienes epilepsia.

  • You have a rare inherited blood condition known as porphyria.

  • Está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como las hierbas medicinales y los medicamentos complementarios.

  • Ha tenido alguna vez una reacción alérgica a un medicamento.

How to take cyproheptadine

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about cyproheptadine tablets and will provide a full list of the side-effects which you may experience from taking them.

  • Take cyproheptadine exactly as your doctor or pharmacist tells you to. The usual recommended doses are:

    • For adults: one tablet (4 mg) three times daily.

    • For children aged 7-14 years: one tablet (4 mg) two or three times daily.

    • For children aged 2-6 years: half a tablet (2 mg) two or three times daily.

  • You can take cyproheptadine before or after meals. Some people find it helps to swallow the tablets with a drink of water.

  • Si olvida tomar una dosis, no se preocupe, tome la siguiente dosis cuando corresponda y continúe como antes. No tome dos dosis juntas para compensar la dosis olvidada.

  • Most people only need to take an antihistamine for a short while when they have symptoms. You should stop taking cyproheptadine once your symptoms have eased.

Aproveche al máximo su tratamiento

  • Cyproheptadine may cause drowsiness. If this happens to you, do not drive and do not use tools or machines. Alcohol will make the drowsiness worse, so it is best not to drink alcohol while you are on cyproheptadine.

  • If you are having an operation or any treatment or tests (particularly if it is to test for an allergy), tell the person due to carry out the treatment that you are taking an antihistamine. This is because you may be advised to stop taking cyproheptadine for a short while before some allergy tests.

  • Cyproheptadine may cause some people's skin to become more sensitive to sunlight than normal. Use a sunscreen that protects against UVA light and has a sun protection factor (SPF) of at least 15, especially in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

  • If you buy any medicines, check with a pharmacist that they are safe to take with an antihistamine. This is because a number of other medicines can interfere with the way cyproheptadine works and can increase the risk of side-effects.
