Can I Take Allergy Medicine With Dayquil?
The short answer is yes – it is generally considered safe to take allergy medicine with DayQuil, especially short-term. However, there are a few precautions regarding ingredients that are important to know.
DayQuil is an over-the-counter cough and cold medication that contains acetaminophen (Tylenol) as a pain and fever reducer, plus decongestants and cough suppressants. Common decongestant ingredients like pseudoephedrine and phenylephrine constrict swollen nasal blood vessels.
Most allergy medications like Claritin, Zyrtec, Allegra and Benadryl block histamines which cause allergy symptoms like a runny nose, watery eyes and sneezing.
DayQuil combined with allergy medicine can provide more complete symptom relief by addressing both allergies and cold/flu viruses at the same time. However, both types of medicines contain active ingredients that can interact with each other, especially with prolonged use.
It’s crucial to closely check both medication labels for the active and inactive ingredients.
Key Ingredient Considerations and Interactions
While DayQuil and allergy medications are generally considered safe together for short-term use, watch out for a few key ingredients:
DayQuil products contain the pain reliever acetaminophen. Many over-the-counter cold medicines also include acetaminophen, which you don’t want to double up on and risk liver toxicity.
Check your allergy medicine ingredients carefully and avoid doubling up on acetaminophen from multiple products. For example, Theraflu capsules contain acetaminophen along with decongestants, so avoid taking Theraflu with DayQuil.
Chlorpheniramine maleate and diphenhydramine are first-generation antihistamines found in medicines like Benadryl and Chlor-Trimeton allergy. These create significant drowsiness.
Other newer second-generation “non-drowsy” antihistamines like loratadine (Claritin), fexofenadine (Allegra) and cetirizine (Zyrtec) are less sedating.
Still, be cautious about combining any antihistamine with DayQuil since both can cause drowsiness and the depressant effects are additive. Carefully monitor your reaction.
Many multi-symptom cold relief products contain decongestants like pseudoephedrine or phenylephrine. So does DayQuil. Doubling up on these constricting agents increases the risk of rapid heart rate, high blood pressure and insomnia.
Carefully read labels and avoid duplicating decongestant ingredients from both allergy and cold combination products. Know what relief each one provides and any ingredient overlap.
This one often gets overlooked. Allergy medicines, cold and flu products, sleep aids plus alcohol are a dangerous depressive combination that impairs coordination, judgment and reaction time.
Avoid alcohol completely when taking DayQuil and allergy or antihistamine medications to prevent unsafe enhancement of CNS depressant effects. Just don’t mix them.
Best Allergy Medicine to Take With DayQuil
If you decide to take DayQuil along with allergy medicine, these options help provide relief while avoiding negative interactions:
- Allegra (Fexofenadine) or Zyrtec (Cetirizine)
- Claritin (Loratadine)
- DayQuil and Benadryl (Diphenhydramine)
1. Allegra (Fexofenadine) or Zyrtec (Cetirizine)
These newer second-generation non-sedating antihistamines are generally recognized as safe to combine with DayQuil. Just monitor in case the depressant effects from both medications make you too drowsy.
Avoid cetirizine brands with phenylephrine like Zyrtec-D unless the DayQuil you take doesn’t contain a decongestant.
Don’t take alcohol when using these allergy meds together with DayQuil.
2. Claritin (Loratadine)
Also a second-generation non-drowsy antihistamine, loratadine has low potential to interact with DayQuil ingredients. It’s considered one of the safer options when used short-term (3-5 days).
Be sure the Claritin product doesn’t also contain a nasal decongestant like pseudoephedrine phenylephrine or a cough suppressant. Plain Claritin tablets reduce allergy symptoms without negative ingredient interactions with DayQuil.
But again, alcohol should be avoided with the combination.
3. DayQuil and Benadryl (Diphenhydramine)
This first-generation antihistamine has more sedative effects compared to newer-generation antihistamines. Combined with DayQuil increases drowsiness and cognitive issues significantly. Use extreme caution when driving or operating machinery.
Also, watch out for any multi-symptom products containing diphenhydramine like Tylenol Severe Allergy. Check labels carefully for duplication and sedative effects.
DayQuil Severe Allergy and Congestion
For those wanting one product for both allergy and cold/flu symptoms, DayQuil now makes Severe Allergy and congestion caplets. They combine acetaminophen, decongestant (phenylephrine) and antihistamine (chlorpheniramine) similar to allergy medicine with the original cold & flu ingredients.
This dual-action formula eliminates negative interactions by combining separate allergy and cold meds containing the same ingredients. It effectively treats upper respiratory allergies plus cold and flu symptoms like cough, congestion, aches and fever.
Just avoid taking additional decongestants, antihistamines or acetaminophen when using the Severe Allergy & Congestion formula.
Safe Dosage Amounts
When taking DayQuil with allergy medicine, never exceed the recommended dosage amounts on either the product label or in this table:
|Total Daily Dose
|120 ml (2-3 doses) every 6-8 hours
|3-6 capsules per day
|Common decongestants like pseudoephedrine and phenylephrine
|240 mg total per day
|No more than 3000 mg per day from all sources
|Vary on product from 1 tablet every 4-12 hours
|No more than one 10mg tablet every 24 hours
|50-100 mg every 4-6 hours usually
Take the minimum effective dosage needed to treat and control symptoms. Exceeding maximum safe amounts increases health risks like liver injury or overdose.
Also, don’t take DayQuil or allergy medicine for more than 7 consecutive days unless directed by your doctor.
When To Avoid Combining DayQuil and Allergy Medications
There are certain higher-risk individuals and medications that should avoid pairing DayQuil with allergy pills:
- People over 60 (increased side effects)
- Pregnant or breastfeeding women
- Children under age 12
- Taking antidepressants (MAO inhibitors, SSRIs etc.)
- Taking sedatives like tranquilizers or sleep medications
- Diabetics – decongestants may increase glucose levels
- Enlarged prostate or urinary retention issues
- Heart disease, high blood pressure, thyroid disease or glaucoma patients – avoid decongestants
- Liver issues – avoid acetaminophen
- More than 2 alcoholic beverages per day
For these populations or conditions, check with your pharmacist or health provider before taking allergy meds with DayQuil. Look into safer natural allergy remedies instead.
Can I Take DayQuil and Allergy Medicine Together Long-Term?
While using DayQuil and allergy relievers together is generally OK short-term (3-5 days), it’s recommended to avoid prolonged use due to the increased risk of side effects.
- Decongestant nasal sprays like Afrin shouldn’t be used longer than 3 days to avoid worsening congestion when stopped.
- Constant diphenhydramine (Benadryl) use risks constipation, urinary retention and increased dementia risk in the elderly.
- The sedation, dizziness and cognitive issues from ongoing antihistamine use also increase fall risks.
- For chronic sinus congestion symptoms or chronic idiopathic urticaria lasting longer than 7-10 days, see your doctor for evaluation rather than continually using over-the-counter allergy and cold combinations long-term.
- Prescription steroid nasal sprays, antihistamine alternatives or allergy shots may be safer options for lasting relief.
Can you take allergy medicine with DayQuil? Yes, when used occasionally and carefully for less than one week.
But be sure to:
- Closely check active ingredients on both products’ labels to avoid duplicating decongestants, antihistamines or acetaminophen
- Watch out for non-drowsy antihistamines that still have some sedative effects
- NEVER mix it with alcohol
- Limit use to less than 7 days
Certain medical conditions also warrant caution with DayQuil and allergy medication combinations. For ongoing symptoms lasting more than one to two weeks, pursue medical advice rather than continual over-the-counter use to identify any underlying causes.
When used properly and for short durations, allergy medicine with DayQuil can safely alleviate congestion along with sneezing and runny noses. However, exceeding safe ingredient doses or durations increases health risks.
Use common sense when combining medications and talk with your pharmacist. Report any alarming side effects to your doctor right away. This helps ensure you find congestion and allergy relief safely.
