No interactions between Vicks Dayquil Cold & Flu Aid and Vitamin D3.
The Food and Drug Administration warns against mixing dietary supplements and medications. Certain dietary supplements, including multivitamins, can affect your body’s ability to absorb, process, or excrete drugs.
The FDA’s list of approved ingredients for over-the-counter cold medications does not allow the combination of vitamin C with the other active ingredients in the two products, the agency said in a warning.
Dangers of Mixing Drugs and Supplements
Combining supplements and drugs can have dangerous and even life-threatening effects. For example, drugs for HIV/AIDS, heart disease, depression, organ transplant treatments, and birth control pills are less effective when taken with St. John’s Wort.
Combining SSRIs and antidepressants with dietary supplements can be particularly dangerous. If you have an anxiety disorder or depression, your doctor may prescribe a selective serotonin reuptake inhibitor (SSRI). Common SSRIs are Lexapro, Prozac, Paxil, and Zoloft.
Do not take multivitamins with milk, other dairy products, calcium supplements, or antacids that contain calcium. Calcium can make it harder for your body to absorb certain ingredients in the multivitamin.
The FDA has approved Procter & Gamble notifies the Company that Vicks DayQuil Plus Vitamin C (acetaminophen, dextromethorphan HBr, phenylephrine HCl, vitamin C) and Vicks NyQuil Plus Vitamin C (acetaminophen, doxylamine succinate, dextromethorphan HBr, vitamin C) for the Cold & Flu Relief…
However, there is controversy over how much time is long enough to wait between doses. A minimum of two hours is usually required, with some sources recommending four to six hours as a minimum.
“Digestion slows down during sleep, so taking your supplement late at night would not be associated with efficient absorption.” Neil Levin, a clinical nutritionist at NOW Foods, agrees that morning is best for multivitamins and all B vitamins.
Because these supplements generally contain both fat and water soluble vitamins, it is usually recommended to take them with a meal. This can improve the absorption of certain nutrients while reducing the risk of gastrointestinal upset that can otherwise occur when taking a multivitamin on an empty stomach.
Take the DayQuil doses 4 hours apart throughout the day. If you use one dose of NyQuil at night, use no more than 3 doses of DayQuil during the day and use less if possible to manage your symptoms. Take your NyQuil dose at night at least 4 to 6 hours after your last DayQuil dose.
Although marketed for daytime use, some people taking DayQuil have reported that it makes them sleepy. Common side effects of DayQuil include nervousness, dizziness, or drowsiness.
Urine: DXM can be detected in urine up to 2 days after the last dose, but standardized drug tests can detect it as PCP (Angel Dust). Blood: DXM can be detected in the blood between 3 and 24 hours after the last dose.
Large doses of minerals can compete with each other for absorption. Do not use calcium, zinc or magnesium supplements at the same time. Plus, these three minerals are easier on your stomach when you take them with a meal. So if your doctor recommends them, take them with different meals or between meals.
Interactions between your medications
No interactions were found between the multivitamin and Tylenol.
Most studies find no benefit of multivitamins in protecting the brain or heart. But there are potential benefits and no risks from a standard daily multivitamin.
Multivitamins that contain large amounts of fat-soluble vitamins can be harmful because excess amounts of these vitamins can build up in the body. For example, excessive intake of vitamin A can cause headaches, liver damage, weaker bones, and birth defects (11).
