Hi can I take zyrtec in the morning and claritin at night?

Hi can I take zyrtec in the morning and claritin at night?

Not the Standard: Hi HPratt, Not really Zyrtec tablets and Claritin are usually once a day meds. They are 2 different antihistamines. Claritin does come in a 12 hour form. So you would take one in the am and one in the pm. Certainly you could use both antihistamines but it is not usually the standard of care. Thanks for your question Dr Lori Lange

Yes: As long as you tolerate the medicines and do not experience drowsiness that is ok. Otherwise ask you doctor for a prescription nasal spray to take with zyrtec.

Several: The treatment of allergies involves three general concepts: avoidance, medicine and immunotherapy. The medicines include antihistamines, nasal steroids and sometime leukotriene blockers. An allergist can help guide one in making the right treatment decisions.

Can I take Zyrtec in the morning and Benadryl (diphenhydramine) at night for postnasal drip? Need relief in the morning. Going to ENT in December.

Can I take Zyrtec in the morning and Benadryl (diphenhydramine) at night for postnasal drip? Need relief in the morning. Going to ENT in December.

Yes: Postnasal drip: Every day, glands in the linings of your nose make about a quart of mucus each day. The excess can come out of the nostrils -- that’s a runny nose. When the mucus runs down the back of your nose to your throat, it's called postnasal drip. Http://www. Webmd. Com/allergies/postnasal-drip

Can I give my 2 year old children's Benadryl (diphenhydramine) at night.... and how much.....she takes zyrtec in the morning?

Can I give my 2 year old children's Benadryl (diphenhydramine) at night.... and how much.....she takes zyrtec in the morning?

Zyrtec (cetirizine) + Benedryl: The occassional use of Benedryl for breakthrough allergy symptoms in addition to regular use of Zyrtec (cetirizine) should generally not cause any problems. Dosing of Benedryl is based on your child's current weight. A simple phone call to your pediatrician should be all that is needed to confirm that the appropriate doses of Zyrtec (cetirizine) and Benedryl are being given.

MOTION SICKNESS: THat combination should be safe, monitor for excess sedation. In chronic URTICARIA you should also block H2 receptor i.e. ZANTAC (ranitidine) 300mg. Make sure at some point in time you have been screened for H. pylori

If I take 5mg of Zyrtec (cetirizine) at night, is it still working come morning and afternoon, or should I take the full 10mg?

Most pollen from: Trees are released at night between 3 AM to 6 AM. So your Zyrtec (cetirizine) should work fine for the time when you need it the most! However if you're in a hyper allergenic environment, you may need the full dose. So if you feel that all you need is the evening and early morning doses the 5 mg may be enough. Let your body be your barometer!

Can I take allegra (fexofenadine) in the morning and zyrtec at night?

See your doctor: This is a high dose of antihistamines and should be best directed by an allergist. Sometimes the high doses are mandated to treat certain conditions, but not seasonal allergies. You should consult an allergist about your symptoms for the best way to treat them.

Is it ok to take Claritin (loratadine) in the morning and Zyrtec at night?

Is it ok to take Claritin (loratadine) in the morning and Zyrtec at night?

No additional benef: Since both of these meds work in very similar ways, there is likely to be very little additional benefit from using both, and much more likely to have side effects from the meds. If one alone is not working, talk to doc about what combination therapy may be more useful, including use of prescription med like Singulair (montelukast). Also need to delve into allergen prevention so you won't need as much meds.

Is it safe to take two zyrtec (cetirizine) a day, one in the morning and one at night?

Is it safe to take two zyrtec (cetirizine) a day, one in the morning and one at night?

Sedation: That dose of zyrtec is going to be very sedating. This defeats the purpose of taking zyrtec instead of benadryl (diphenhydramine). That level of sedation will make you a drowsy --> dangerous driver. Have you tried Loratadine or allegra? Do you use Flonase or something like it? Do you regularly flush your nose with a saline/ baking soda solution?

Zyrtec (cetirizine) is only effective for 10 hours for me. Is there any other medication I can take at night to help my allrrgies along with zyrtec (cetirizine) in the morning?

More zyrtec (cetirizine) for nose: zyrtec (cetirizine) can be taken safely more than the package states. It can cause some drowsiness in about 13% of people; that's why the low dose of ten mg is recommended. The simplest answer to your problem is to simply take another zyrtec (cetirizine) at night, if your morning dose doesn't last all day.

My daughter takes Allegra in the morning and Zyrtec at night. Is this safe?

Allegra and Zyrtec: Both have the same action. There is no point in taking them on the same day. You may alternate as the action lasts for 24 hours for 180 mg of Allegra and 10 mg of Zyrtec.

Is it safe to mix hydroxyzine and valium? E.g. 5mg valium in the morning, then hydroxyzine at night? If on it do you still need to take zyrtec 4allerg

Is it safe to mix hydroxyzine and valium? E.g. 5mg valium in the morning, then hydroxyzine at night? If on it do you still need to take zyrtec 4allerg

Ok: Since you are taking hydroxyzine at night, it is fine as long as you are not working a nightshift since this may make you drowsy. Zyrtec is simply a more pure form of hydroxyzine with less drowsiness effect and thus you may not need to take a Zyrtec for allergy. However it can be added if necessary.

Can I take Claritin (loratadine) in the morning and zyrtec at night. Allergies are just that bad..

Should be OK: I have also found that seasonal allergies can benefit from a sinus rinse using a Neilmed (for example), a little teapot like container with saltwater. If you take the antihistamine in the am and pm I do not think they have to be the same brand.

I take a generic version of zyrtec (cetirizine) in the morning can I take alka seltzer cold and cough at night?

I take a generic version of zyrtec (cetirizine) in the morning can I take alka seltzer cold and cough at night?

Yes: And if you can quit smoking, you'd get sick much less! Don't forget that in the winter, our noses need moisture--even when we think they are stuffy. Many times they are asking for moisture. I like ayr saline gel spray as it sticks and doesn't run down the back of your throat. Steroid nasal sprays are helpful too!

Zyrtec (cetirizine) dose: Yes, you can take more zyrtec (cetirizine) total per day if you tolerate it well. When patients have severe urticaria, we often have them take even more than 4 zyrtec (cetirizine) tablets daily. The initial studies with zyrtec (cetirizine) used doses of 10-40 mg, or up to 4 tablets at a time. You can still take the ranitidine and montelukast at night also, if they help you. They do not affect the dose of antihistamine.

You need. .: Professional evaluation, to get to the root of that headache, even if it is just a sinus headache, you may have sinusitis that need antibiotics or other prescription strength medications, kindly see your doctor, an allergist /ENT for evaluation, good luck
