BENADRYL® Allergy Plus Congestion

BENADRYL® Allergy Plus Congestion contains phenylephrine, which relieves nasal congestion. With this, it relieves all the same symptoms as BENADRYL®, plus it provides fast congestion relief. For more information on BENADRYL® Allergy, see: What symptoms does Oral BENADRYL® Allergy relieve? For more information on decongestants.

BENADRYL® Allergy Plus Congestion contains a nasal decongestant that works by narrowing the blood vessels in the nose that expand during allergies or infection with the common cold. When these blood vessels narrow, the tissue shrinks and allows the normal flow of air and mucus. This results in the temporary relief of nasal congestion, sinus congestion, and sinus pressure. For more tips on how to combat congestion, read our guide on nasal congestion here.

Both pseudoephedrine and phenylephrine are decongestants that help relieve the symptoms of nasal and sinus congestion, as well as sinus pressure. BENADRYL® Allergy Plus Congestion contains phenylephrine, which helps alleviate these symptoms as well as other allergy symptoms for 4 hours. There are no BENADRYL® products that contain pseudoephedrine.

No. Phenylephrine is available to the public over the counter.

Since the inception of this “challenge” we’ve taken action to stop this behavior. The content adolescents are exposed to on social media has a very real impact on their lives and urgency needs to be taken to remove all dangerous content. We have held discussions with TikTok safety & policy teams, as well as other social media platforms, about the need to take immediate action as it relates to content on medicine misuse and abuse, but we continue to be deeply concerned with the dangerous content available to youth on social media. We have also partnered with organizations such as the Community Anti-Drug Coalitions of America (CADCA) and Partnership to End Addiction via the Consumer Healthcare Product Association (CHPA) to help educate parents and caregivers on the dangers of participation in challenges and help them understand how they can help identify and address this concerning adolescent behavior.
