Can i take loratadine in the morning and benadryl at night

Seasonal allergies are the worst. At first, you're overjoyed to see all the greenery popping up after a long winter. Then the next thing you know, your eyes are red, your nose is runny, and—worst of all—you're sneezing 24/7. So, you grab your go-to antihistamine to help relieve those symptoms. But what is the best time to take allergy meds for maximum effectiveness?

Most people don't pop that pill until they're already dragging through their morning. That's why experts say you should actually be taking your antihistamines before you go to bed at night.

"Antihistamines take at least 30 minutes to work, and the newer, long-acting ones will last you 24 hours, so you'll be covered until the next day. They work best when they're already in your system, so the night before is most efficacious," says Purvi Parikh, MD, an allergist/immunologist with the Allergy & Asthma Network. "Since some antihistamines make you drowsy, it's actually best to take them before bedtime."

Bonus: Taking them ahead of time means you'll rise just in time for them to reach the prime allergy-fighting zone. "Once-daily antihistamines reach their peak efficacy 8 to 12 hours after you take them, so using them at dinnertime or before bed means better control of your daytime symptoms," says Yoon Mi Kim, DO, an allergy and immunology specialist for Geisinger.

As long as you're consistent and try to take your meds prior to exposure, Dr. Parikh says any time will work. But for anyone who dreams of waking up without the sniffles, you can't beat swallowing the pill before you get ready for some shut-eye.

Yes you can: it might make you a bit more sleepy. But that should not be a problem now that it is time to sleep.

How long after loratadine can I take Benadryl?

“It may not be safe to take Benadryl until 12 hours after taking Claritin,” Dr. Glatter says. (Dr. Raimo takes that a step further, advising patients to avoid taking these two medications within 24 hours of each other.)

Can you take loratadine and Benadryl in the same day?

Different oral antihistamines such as diphenhydramine, cetirizine, loratadine, levocetirizine, desloratadine, and fexofenadine should never be taken together. Taking different oral antihistamines together can lead to an antihistamine overdose.

What happens if you take Benadryl and Claritin?

No interactions were found between Benadryl and Claritin. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.

Can I take an allergy pill and Benadryl in the same day?

Two common over-the-counter medications, Benadryl (diphenhydramine) and Claritin (loratadine), can make short work of your symptoms. So it's natural to wonder: Could you get extra relief if you take them together? The short answer is no. In fact, you'll likely do more harm than good.
