Yes, Zyrtec and Sudafed can be taken together. There are no interactions between the medications, and they work in different ways. So, as long as it's safe for you to take either one of them, you can take them at the same time. But always check with your healthcare provider before taking a new medication.
It's safe for most people to take allergy medications that are in different classes. For example, nasal steroids and oral decongestants can be taken together. However, you shouldn't combine oral antihistamines, such as Zyrtec and Benadryl, without a healthcare provider's OK.
Is Mixing Allergy Meds Safe? You can safely mix different types of allergy medications, like Flonase, a nasal spray, and Claritin, an antihistamine. In fact, it's often recommended by doctors.
Zyrtec may interact with other medicines that make you sleepy (such as other cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety).
No interactions were found between Claritin and Zyrtec. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
The recommended maximum number of medicines in the 'antihistamines' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'antihistamines' category: Claritin 24 Hour Allergy (loratadine) Zyrtec (cetirizine)
Why do antihistamines stop working? Antihistamines can stop working because your allergies might be getting worse or you might have immune system changes due to aging. You also might not be taking the medication as directed. If you take an antihistamine after being exposed to an allergy trigger, it won't work as well.
Taking more than the usual dose is unlikely to harm you or your child. If you take an extra dose, you might get some of the common side effects. If this happens or you're concerned, contact your doctor.
Do not take 2 antihistamines together unless recommended by your doctor.
Adults and children 6 years and older Chew and swallow 2 tablet (10 mg) once daily; do not take more than 1 tablet (10 mg) in 24 hours. A 5 mg product may be appropriate for less severe symptoms. Adults 65 years and over Ask a doctor.
But there's another possibility: Often when allergy medicine stops working, the problem is that your allergies or symptoms have gotten worse and you need to change your treatment accordingly. If you're no longer getting the symptom control you once did from your allergy medication, speak to your healthcare provider.
In overdose symptoms can include dizziness, tachycardia, headache drowsiness or agitation. While the current generation of lesser sedating antihistamines do not affect the QT interval at normal doses (unlike the previous generation of medicines), there are concerns there may be some effect in overdose.
Cetirizine can be taken at any time of the day. In most people it is non-sedating, so they take it in the morning. However, a percentage of people do find it to be sedating so if it does make you drowsy it is best to take it in the evening. Cetirizine can be taken with or without food.
Taking too much antihistamine can lead to adverse side effects and a potential antihistamine overdose. Antihistamines are a class of medication that treat allergy symptoms, such as sneezing, runny nose, and itching. As with any medication, taking too much can be harmful.
Benadryl. Benadryl (diphenhydramine) is the strongest and most effective first-generation antihistamine, says Roberto Garcia-Ibáñez, M.D., a board-certified allergist and immunologist at The Allergi Group in Tampa, Florida. It's often administered in the emergency room to treat an allergic reaction, he adds.
The maximum recommended daily dose is 20 mg, do not exceed this dose, unless told to do so by your doctor. The usual dose of ZYRTEC oral solution is 10 mL, once a day. In children over 6 years of age, the daily dose of 10 mg is given as a single or divided dose.
Official answer. No, the maximum recommended daily dose of loratadine is 10mg once daily.
For many people with allergies, symptoms are the worst around 4 a.m. to 6 a.m. Taking an antihistamine at bedtime may help you or your child feel better in the morning during allergy season.
If steroids and other hay fever treatments do not work, your GP may refer you for immunotherapy. This means you'll be given small amounts of pollen as an injection or tablet to slowly build up your immunity to pollen. This kind of treatment usually starts in the winter about 3 months before the hay fever season begins.
Allevia Fexofenadine 120 mg strong Hayfever Tablets provide relief that lasts all day from 7 hayfever symptoms in just 1 tablet, including sneezing, itchy, red, watery eyes, itchy, blocked, and runny nose.
Cetirizine reaches peak plasma concentration after approximately one hour. Its effects typically begin after 20 to 60 minutes and persist for at least 24 hours. Food does not affect the extent of exposure (AUC) of cetirizine, but the time to attain peak concentration is delayed by 1.7 hours.
Don't take more than 1 tablet in 24 hours. Children's Zyrtec (ages 2+) chewable tablets contain 2.5 mg of cetirizine per tablet. If you are under 65 years old, chew and swallow 2 to 4 tablets (5 mg to 10 mg) once daily. Don't take more than 4 tablets in 24 hours.
“Claritin is a 24-hour antihistamine that works in the same way as Zyrtec, however, research has found that Claritin may be less potent than Zyrtec and therefore less effective,” explains Dr. Parikh. Although potential side effects may also be minimized as a result, she adds.
It's not a great idea, but an isolated incident of taking two Zyrtec is unlikely to have major health effects. In fact, some doctors double the dose of Zyrtec for their patients with severe hives if a single pill isn't working.
