Cyclizine is used to treat sickness (nausea), such as that caused by problems affecting the inner ear and balance (including mareos), and travel sickness. It is an antihistamine.
Cyclizine helps reduce the feelings of nausea and vertigo caused by problems such as these. It is available from a pharmacy, without a prescription, and can be taken by adults and by children over the age of 6 years.
Before taking cyclizine
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking cyclizine it is important that your doctor or pharmacist knows:
Si estás embarazada o amamantando.
If you have any problems with the way your liver works, or if you have heart failure.
If you have increased pressure in your eye, a condition called glaucoma.
Si tienes epilepsia.
If you have prostate problems, or have been experiencing difficulty passing urine.
Si sabes que tienes una obstrucción en tus intestinos delgados.
Si tienes un trastorno sanguíneo hereditario raro llamado porfiria.
Si está tomando otros medicamentos. Esto incluye cualquier medicamento que se pueda comprar sin receta, así como medicamentos herbales y complementarios.
Si alguna vez has tenido una reacción alérgica a un medicamento.
How to take cyclizine
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about cyclizine, and it will also provide you with a full list of the side-effects which you could experience from taking it.
Take cyclizine exactly as your doctor or pharmacist tells you to. It can be taken up to three times a day.
If you are taking cyclizine to prevent travel sickness, take the first tablet 1-2 hours before you are due to travel. If you are going on a long journey, you can then take further doses every eight hours if needed. The tablets can be crushed to make them easier to swallow. If you are giving cyclizine to a child, check the label carefully to make sure you are giving the correct dose for the age of your child - the dose for children aged 6-12 years is half a tablet.
Obteniendo el máximo de tu tratamiento
Cyclizine can cause drowsiness and blurred vision. Although this is rare following a single dose of cyclizine, it can occur if it is taken more regularly. If this happens, 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 cyclizine.
If you are having an operation or any treatment (particularly if it is to test for an allergy), please tell the person carrying out the treatment that you are taking cyclizine.

Preguntas frecuentes
Can I take cyclizine if I am elderly?
Yes, cyclizine can be taken by adults. However, older individuals, particularly the elderly, should be aware that feeling restless or excited is a less common side effect. If this symptom occurs, it is advised to stop taking the medication and consult with a doctor.
What should I do if I forget to take a dose of cyclizine?
The article advises taking cyclizine exactly as your doctor or pharmacist tells you to, up to three times a day. If you are taking it for travel sickness, the first dose should be 1-2 hours before travel, and then further doses every eight hours as needed. There are no specific instructions for a forgotten dose, so it's best to continue with your next scheduled dose when you remember, without taking a double dose.
How long can I safely use cyclizine for?
The article does not specify a maximum duration for using cyclizine. It mentions that some unwanted effects often improve as your body adjusts to the new medicine. If you have concerns about long-term use, or if side effects continue or become troublesome, you should speak with your doctor or pharmacist.
Is cyclizine suitable for children younger than 6 years old?
Cyclizine is indicated for use by children over the age of 6 years. The article does not mention its suitability or dosage for children younger than 6 years, implying it should not be given to this age group without specific medical advice.
Can I take other cold or flu remedies at the same time as cyclizine?
Before taking cyclizine, it's important to inform your doctor or pharmacist about any other medicines you are taking. This includes any medicines available without a prescription, such as cold or flu remedies, as well as herbal and complementary medicines. This ensures there are no potential interactions or suitability concerns.
