If a healthy adult takes only a slightly higher dose of antihistamine, such as accidentally taking two pills instead of one, their symptoms may not be serious, or they may not have any symptoms.
However, a larger overdose, especially in children or older adults, may cause serious symptoms. Toxic doses of antihistamines may happen when a person takes 3 to 5 times the normal amount.
No matter how much a person overdoses, they should seek medical help or call a poison control center. Research shows that first generation antihistamines can have effects on the central nervous system in large doses. Second generation antihistamines do not usually have these effects. Second-generation antihistamines are commonly used medications, including:. Second generation antihistamines tend to be less serious with an overdose. However, any overdose can be dangerous, and people should seek help from a medical professional or poison control immediately.
If a person has severe symptoms, such as trouble breathing, fast or slow heart rate, seizures, or loss of consciousness, call or go to the nearest emergency room.
Some antihistamines are safe for children to take. However, the Food and Drug Administration FDA caution that just because a product says it is for children does not mean a child of any age can take it.
Research on antihistamines says that children and older adults are more at risk of an antihistamine overdose than adults. One study found that children have experienced heart problems, seizures, and even death from an antihistamine overdose. The most common reactions are mild, however, and include:. Second generation antihistamines are less likely to cause toxicity in children than first generation ones, according to a study of more than 9, children.
However, another study found that second generation antihistamines can cause dangerous symptoms when children overdose on them. Diagnosing an antihistamine overdose usually starts with a discussion about all medications the person is taking and not just the antihistamines. This is because some other medications, such as cold, flu, and sleep medications, contain antihistamines.

If your doctor or health visitor says your baby is healthy, you can take cetirizine while breastfeeding. There is some information available which shows that only very small amounts get into breast milk. Cetirizine has been used for many years while breastfeeding without side effects in babies.
If your baby is not feeding as well as usual, seems unusually sleepy, or if you have any other concerns about your baby, talk to your doctor, pharmacist, health visitor or midwife. Some medicines can increase the chances of you having side effects with cetirizine.

Tell your doctor or pharmacist if you're taking any other medicines, including herbal medicines, vitamins or supplements. Cetirizine is a type of medicine called an antihistamine.
When you come into contact with something you're allergic to, such as pollen, animal hair or fur, your body produces a chemical called histamine. Usually histamine is a useful substance, but in an allergic reaction it causes unpleasant symptoms including itchy, watery eyes, a running or blocked nose, sneezing and skin rashes. For example, if you have a reaction to an insect bite, you may only need to take cetirizine for a day or two. You may need to take cetirizine for longer if you're taking it to prevent symptoms — for example, to stop hay fever when the pollen count is high.
Talk to your doctor or pharmacist if you're unsure how long you need to take cetirizine for. However it's best to take cetirizine only for as long as you need to.
If you take it regularly over a long period there's a very small chance of severe itching if you stop treatment suddenly. If you've been taking cetirizine every day for a long time, talk to your doctor before stopping it.
It's best not to drink alcohol while you're taking cetirizine as it can make you feel sleepy. Cetirizine is classed as a non-drowsy antihistamine, but it's still possible to feel sleepy after taking it. If this happens to you, do not drive a car, ride a bike, use tools or machinery until you do not feel tired anymore.
It's an offence to drive a car if your ability to drive safely is affected. It's your responsibility to decide if it's safe to drive. If you're in any doubt, do not drive.
Talk to your doctor or pharmacist if you're unsure whether it's safe for you to drive while taking cetirizine. UK has more information on the law on drugs and driving.

An exception is when you want the medicine to make you sleepy — for example, if you have itchy skin that's keeping you awake. Other non-drowsy antihistamines, such as loratadine , desloratadine, fexofenadine and levocetirizine, seem to work just as well as cetirizine.
But cetirizine seems to be more likely to make you feel sleepy than loratadine, desloratadine or fexofenadine. Yes, you can take cetirizine together with paracetamol or ibuprofen. Sometimes doctors recommend that people with a severe, itchy skin rash take 2 different antihistamines together for a few days.

Yes, it's fine to take cetirizine together with some other hay fever treatments — for example, steroid nasal sprays such as beclometasone Beconase , Rhinocort Aqua and Flixonase Nasules or eye drops.
Your doctor may prescribe a higher dose of cetirizine up to 4 times the usual dose for you or your child, for a severe, itchy skin rash or swelling under the skin angioedema. Taking high doses of cetirizine is not suitable for everyone though. Speak to your doctor if you think cetirizine is not working for you. There's no evidence to suggest that taking certirizine will reduce fertility in either men or women.
Speak to a pharmacist or your doctor before taking it if you're trying to get pregnant. Cetirizine does not affect any type of contraception, including the combined pill and emergency contraception.
However, if cetirizine makes you vomit or have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy.
