Is It Safe to Take NyQuil & Antibiotics Together? Interaction Insights

Can You Take NyQuil and Antibiotics Together?

When you're sick with a cold or the flu, taking medications like NyQuil can help relieve your symptoms so you can start feeling better. But what if you're also taking antibiotics for an infection? Is it safe to mix the two? There are a few things you should know first.

How NyQuil and Antibiotics Work in the Body

To understand if you can take NyQuil and antibiotics simultaneously, it helps to know what each medication does:

• NyQuil contains a combination of the pain reliever acetaminophen, the cough suppressant dextromethorphan, the antihistamine doxylamine succinate, and the nasal decongestant phenylephrine.
• Antibiotics like amoxicillin, azithromycin, and ciprofloxacin are used to treat or prevent bacterial infections. They work by killing the bacteria or preventing them from multiplying.

Risk of Adverse Side Effects

While NyQuil and antibiotics generally do not have major interactions or contraindications, taking them at the same time does come with some risks:

• The sedative effects of the antihistamine in NyQuil may be intensified by certain antibiotics like clarithromycin or azithromycin.
• Acetaminophen found in NyQuil can affect kidney function. This risk may increase when combined with antibiotics that also impact kidney function, like gentamicin or tobramycin.
• Certain antibiotics like doxycycline can increase your skin's sensitivity to the sun. NyQuil's antihistamine, doxylamine succinate, may have a similar effect.

Safety Recommendations

If your doctor or pharmacist has approved using NyQuil and an antibiotic together, here are some tips to reduce your risk of complications:

• Take acetaminophen/paracetamol-free varieties of NyQuil to lower your risk of kidney problems.
• Avoid driving or hazardous activities as the combination may increase drowsiness.
• Use sun protection if taking doxycycline or doxylamine succinate to prevent sunburns.
• Space out your doses - take the antibiotic and NyQuil at least 2-4 hours apart.

When recovering from illness, following your provider's treatment recommendations is important - even when it involves mixing over-the-counter and prescription medications.

However, side effects can occur, especially if doses are not properly spaced out. Certain higher risk groups also need to take greater precautions when using both simultaneously.
