If this sounds familiar, you are not alone. <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/amoxicillin\"><span style=\"font-weight: 400;\">Amoxicillin<\/span><\/a><span style=\"font-weight: 400;\"> is a commonly called upon drug from the penicillin family, but it takes time for it to clear an infection. <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/vicks-dayquil-cough\"><span style=\"font-weight: 400;\">DayQuil<\/span><\/a><span style=\"font-weight: 400;\">, a popular over-the-counter (OTC) cold medication, can help treat symptoms of sinus and ear infections. But can you take DayQuil to block the symptoms while amoxicillin tackles the cause? Here\u2019s what you should know.<\/span><\/p>\n<h2 id=\"can-you-take-dayquil-and-amoxicillin-together\"><span style=\"font-weight: 400;\">Can you take DayQuil and amoxicillin together?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Taking DayQuil along with amoxicillin is typically fine. The ingredients of DayQuil do not interact with amoxicillin. If amoxicillin was prescribed for you because your healthcare provider thought it would be safe and effective, the real question is whether taking Dayquil could provide a benefit or pose a risk to you. For that matter, it\u2019s important to ask your healthcare provider who is familiar with any other conditions you have and other medications you may be taking.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Healthcare professionals may consider the ingredients of DayQuil products to be worthwhile for some patients. <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/vicks-dayquil-nyquil-cld-flu\"><span style=\"font-weight: 400;\">DayQuil Cold and Flu<\/span><\/a><span style=\"font-weight: 400;\"> has multiple active ingredients: the analgesic and antipyretic <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/acetaminophen\/what-is\"><span style=\"font-weight: 400;\">acetaminophen<\/span><\/a><span style=\"font-weight: 400;\"> for relief from pain and fever, the <\/span><a href=\"https:\/\/www.singlecare.com\/drug-classes\/antitussives\"><span style=\"font-weight: 400;\">cough suppressant<\/span><\/a> <a href=\"https:\/\/www.singlecare.com\/prescription\/dextromethorphan-hbr\"><span style=\"font-weight: 400;\">dextromethorphan<\/span><\/a><span style=\"font-weight: 400;\">, and nasal decongestant phenylephrine.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although less coughing, congestion, and pain would be welcomed by anyone suffering with upper respiratory symptoms, DayQuil may not always deliver on its symptom relief claims. In 2023, <\/span><a href=\"https:\/\/www.fda.gov\/drugs\/drug-safety-and-availability\/fda-clarifies-results-recent-advisory-committee-meeting-oral-phenylephrine\"><span style=\"font-weight: 400;\">the Food and Drug Administration (FDA) reported<\/span><\/a><span style=\"font-weight: 400;\"> that phenylephrine was ineffective. The <\/span><a href=\"https:\/\/www.fda.gov\/news-events\/press-announcements\/fda-proposes-ending-use-oral-phenylephrine-otc-monograph-nasal-decongestant-active-ingredient-after\"><span style=\"font-weight: 400;\">FDA followed this up in 2024<\/span><\/a><span style=\"font-weight: 400;\"> by proposing that products like DayQuil Cold and Flu stop using phenylephrine. While it may be acceptable to take DayQuil with amoxicillin, these FDA reports could make one wonder whether it is worth it.<\/span><\/p>\n<h2 id=\"dayquil-vs-amoxicillin-key-differences\"><span style=\"font-weight: 400;\">DayQuil vs. amoxicillin: Key differences<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Amoxicillin and DayQuil could be a drug duo that works together for sinus infections, ear infections, or pneumonia. While they might be used concurrently, they are more different than alike.<\/span><\/p>\n<h3 id=\"drug-class\"><span style=\"font-weight: 400;\">Drug class<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Each comes from a different category of medicine. Amoxicillin is a <\/span><a href=\"https:\/\/www.singlecare.com\/drug-classes\/penicillins\"><span style=\"font-weight: 400;\">penicillin antibiotic<\/span><\/a><span style=\"font-weight: 400;\">\u2014more specifically an aminopenicillin that is effective for many bacterial infections. It is produced alone or in tandem with clavulanic acid in <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/augmentin\/what-is\"><span style=\"font-weight: 400;\">Augmentin<\/span><\/a><span style=\"font-weight: 400;\">. In comparison, DayQuil has a number of different products under its umbrella name, but they all have multiple ingredients from different drug classes, with a focus on relieving cough and cold symptoms while avoiding daytime drowsiness.<\/span><\/p>\n<h3 id=\"dosing\"><span style=\"font-weight: 400;\">Dosing<\/span><\/h3>\n<p><a href=\"https:\/\/dailymed.nlm.nih.gov\/dailymed\/drugInfo.cfm?setid=42f935ca-45ba-4b3e-8b40-9b2d4eb56281\"><span style=\"font-weight: 400;\">Amoxicillin<\/span><\/a><span style=\"font-weight: 400;\"> is available in tablet and liquid form. Usually, it is taken two to three times per day. <\/span><a href=\"https:\/\/dailymed.nlm.nih.gov\/dailymed\/drugInfo.cfm?setid=416c6674-e4aa-6375-e054-00144ff8d46c\"><span style=\"font-weight: 400;\">DayQuil<\/span><\/a><span style=\"font-weight: 400;\"> can also be purchased in tablet or liquid version, but its dosing is on an as-needed basis. Depending on which DayQuil product is being used, dosing could be every four to six hours, but you will need to rely on the product\u2019s instructions to be sure.<\/span><\/p>\n<h3 id=\"cost\"><span style=\"font-weight: 400;\">Cost<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The out-of-pocket expense can be very different between these drugs. Generic amoxicillin is typically covered by insurance, but OTC DayQuil is often not covered. Without insurance, their prices are fairly comparable. Amoxicillin retails for about $20 for 21, 500 mg capsules, while the DayQuil and Nyquil Cold and Flu package costs about that much for 48 tablets. DayQuil Cough syrup is priced similarly at $14 for 1, 354 mL bottle.<\/span><\/p>\n<h3 id=\"restrictions\"><span style=\"font-weight: 400;\">Restrictions<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Restrictions may apply to one drug but not the other. Amoxicillin is generally safe in the setting of heart disease and typically is considered compatible with pregnancy and breastfeeding. It is also used extensively in children of all ages. On the contrary, it might be best for those who are pregnant or have heart disease to avoid Da<\/span>yQuil Cold and Flu. Likewise, safety concerns <a href=\"https:\/\/www.fda.gov\/drugs\/special-features\/use-caution-when-giving-cough-and-cold-products-kids\">limit the use of DayQuil in children<\/a> and lead to complete avoidance in children under 6.<\/p>\n<table class=\" singlecare-table\">\n<thead>\n<tr>\n<th>\n<h2 id=\"dayquil-vs-amoxicillin-comparison-chart\"><span class=\"title\">DayQuil vs. amoxicillin: Comparison chart<\/span><\/h2>\n<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr class=\"header-row\">\n<td><\/td>\n<td><span style=\"font-weight: 400;\">DayQuil<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Amoxicillin<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Drug class<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Combination cold medicine<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Antibiotic<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Standard dosage and forms<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Tablets, capsules, or liquids with multiple products having various combinations of ingredients<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Tablets, capsules, or liquids with usual adult dosing of 500\u20131,000 mg every 8\u201312 hours<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Risks and restrictions to consider<\/span><\/td>\n<td>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid in patients under 6 years old<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid DayQuil products that contain phenylephrine if you\u00a0 have heart disease\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid DayQuil products that contain phenylephrine if pregnant<\/span><\/li>\n<\/ul>\n<\/td>\n<td>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid if allergic to penicillin<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avoid in the setting of C. diff diarrhea<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Side effects<\/span><\/td>\n<td>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"> Nausea<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">\u00a0Hypertension<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">\u00a0Anxiety<\/span><\/li>\n<\/ul>\n<\/td>\n<td>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"> Nausea<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">\u00a0Diarrhea<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">\u00a0Allergic reaction<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Average cost without insurance<\/span><\/td>\n<td><span style=\"font-weight: 400;\">$14 for 1, 354 mL bottle of 15 mg\/15 mL DayQuil Cough<\/span><\/td>\n<td><span style=\"font-weight: 400;\">$19 for 21, 500 mg capsules<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">SingleCare cost*<\/span><\/td>\n<td><a class=\"cta-button\" href=\"https:\/\/www.singlecare.com\/prescription\/vicks-dayquil-cough\"><span style=\"font-weight: 400;\">Get coupon<\/span><\/a><\/td>\n<td><a class=\"cta-button\" href=\"https:\/\/www.singlecare.com\/prescription\/amoxicillin\"><span style=\"font-weight: 400;\">Get coupon<\/span><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h5><span style=\"font-weight: 400;\">*Cost at time of publication.

Although combining multiple medications in one cold medicine is convenient, it could cause adverse effects.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Acetaminophen is a safe pain reliever that avoids many of the downsides of its counterpart ibuprofen, including being able to be used together with blood thinners. Unfortunately, acetaminophen can be toxic to the liver in overdose. While this may not seem applicable at first glance, it is a real cause of concern, because acetaminophen is included in many cold medications and is the active ingredient in the fever-reducer Tylenol. The FDA has even <\/span><a href=\"https:\/\/www.fda.gov\/consumers\/consumer-updates\/dont-overuse-acetaminophen\"><span style=\"font-weight: 400;\">called attention to the hazards of accidental acetaminophen overdose<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dextromethorphan may be a helpful agent for suppressing cough, but it has drug interactions with a number of common medications based on its serotonin effect. For example, taking dextromethorphan alongside a selective serotonin reuptake inhibitor (SSRI) antidepressant can increase the risk of serotonin syndrome, a life-threatening drug reaction. Have your healthcare team review all of your prescription drugs, OTC remedies, and supplements before taking DayQuil.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The decongestant phenylephrine has its own set of hazards. Hypertension and heart arrhythmia are listed among its serious side effects, and anxiety and insomnia are common side effects. If you have heart disease, high blood pressure, or anxiety already, your healthcare provider may not want you to take phenylephrine.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To reiterate, DayQuil and amoxicillin can be taken together. They do not negate the other\u2019s effectiveness, and they do not escalate one another\u2019s adverse effects. However, the risks of amoxicillin and each ingredient in DayQuil must be carefully examined. Taking them both together could simultaneously add four new drugs to your medication list, putting you in harm\u2019s way of side effects and interactions with your health conditions and other medicines you may be taking. Rely on your healthcare provider to help you determine whether to take DayQuil while being treated with amoxicillin.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stricken with a sinus or ear infection, being treated with the antibiotic amoxicillin, and wondering what can be done for your nasal congestion, cough, and pain while you are waiting for the antibiotic to work?
