Combining Benadryl with DayQuil: Is It Safe?
I’m a 21-year-old woman, and at the moment, I’m unable to purchase NyQuil due to the late hour when all stores are shut. I wanted to inquire whether it would be appropriate to take both Benadryl and DayQuil together to achieve similar relief as that offered by NyQuil. Thank you for your help, and I hope my question isn’t considered silly.

Combining Benadryl (diphenhydramine) with DayQuil (which typically contains acetaminophen, dextromethorphan, and phenylephrine) is not recommended without careful consideration. While it may not have immediate harmful effects for all individuals, there are potential side effects and interactions to keep in mind.
Explanation:
Benadryl is an antihistamine commonly used to relieve allergy symptoms and can cause drowsiness. DayQuil is a multi-symptom medication effective for relieving cold and flu symptoms but is designed to keep you awake. Mixing these medications can lead to increased side effects, such as heightened drowsiness or confusion, especially since both can impact your central nervous system differently.
Next Steps:
- Avoid Mixing: It is best to avoid taking Benadryl and DayQuil together due to the risk of increased drowsiness and other side effects.
- Take One Medication: Choose either Benadryl or DayQuil based on your symptoms:
- If you have significant allergy symptoms or need help sleeping, go with Benadryl.
- If you have cold or flu symptoms such as cough and nasal congestion and need to stay alert, choose DayQuil.
- Hydration: Drink plenty of fluids to help alleviate symptoms.
- Monitor Symptoms: Keep track of any changes in how you feel after taking either medication.
If your symptoms persist or worsen, consider reaching out to a healthcare professional for personalized advice. Your concerns are valid, and I hope this guidance helps!

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies
Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.
Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?
Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!
Concerns About Hearing Loss After Extended Earphone Use
For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?
Experiencing Headaches and Vision Changes on One Side
Hello, I'm an 18-year-old female, and I've been on a 15mg dose of Isotretinoin for my acne treatment for about a month now. Recently, I've been feeling under the weather, dealing with a viral infection that resembles cold or flu symptoms. I've got the usual problems like nasal congestion and a throat that hurts, but I've also noticed some joint discomfort, a sense of mental cloudiness, and an unsettling change in my vision, making it appear distorted as if seen through a low-resolution lens. Additionally, when I change my position from sitting to standing, there's an intense throbbing sensation on the right side of my head, accompanied by a momentary blackout in my right eye. I must admit, my nutritional intake has not been great lately due to feeling fatigued from the cold, and this has been accompanied by headaches and a notable darkening of my vision when I stand, which is something I've never before experienced just on one side until now. I tend to get quite anxious about my health, so I'm reaching out to see if anyone else has encountered similar symptoms with a cold, or if this could be associated with the Isotretinoin I'm taking? Any insights or advice would be greatly appreciated, thank you!
Dealing with Possible Epididymitis
A male, aged 40, standing at 5'9" and weighing 10.5 stone, presents a health concern. He has a history of smoking but refrains from alcohol consumption. For several years, I've grappled with a weakened bladder. However, over the last year or two, I've been experiencing intense discomfort in my right testicle. Initially, I thought I discerned a lump, prompting me to reach out to a physician. Unfortunately, the advice I received was limited; the doctor recommended an STI screening without conducting any examinations. I complied with the test, which returned negative results. Although the pain subsided briefly, it has now returned with greater intensity. I have undergone blood tests focusing on kidney, bladder, and prostate functions, all of which yielded normal results. Now, the medical team is leaning towards a diagnosis of epididymitis. The pain is excruciating and difficult to endure. I’ve scheduled an appointment for a prostate and testicular examination, which may lead to an ultrasound scan or possibly a urethral procedure to eliminate any serious underlying issues. The thought of the forthcoming examination fills me with anxiety, as I'm certain it will be painful. I'm curious if anyone has experienced epididymitis and what outcomes you faced, including any surgical interventions that may have been necessary.
