ToggleWhat Is Theraflu and How Does It Work
Theraflu combines multiple active ingredients to target various cold and flu symptoms. The medication contains acetaminophen for pain relief and fever reduction, dextromethorphan HBr as a cough suppressant and phenylephrine HCl for nasal congestion relief.
Each Theraflu formulation targets specific symptoms:
- Severe Cold & Cough: Contains 650mg acetaminophen, 20mg dextromethorphan, 10mg phenylephrine
- Nighttime Severe Cold & Cough: Adds diphenhydramine for sleep aid
- Daytime Severe Cold & Cough: Includes guaifenesin as an expectorant
- Max Severe Cold & Flu: Features higher doses of active ingredients
| Active Ingredient | Primary Function | Typical Dosage |
|---|---|---|
| Acetaminophen | Pain/Fever Relief | 325-650mg |
| Dextromethorphan | Cough Suppression | 10-20mg |
| Phenylephrine | Decongestant | 5-10mg |
| Diphenhydramine | Antihistamine | 25-50mg |
The medication works by:
- Blocking pain signals to reduce body aches
- Lowering fever through temperature regulation
- Suppressing cough reflex in the brain
- Shrinking swollen nasal passages
- Thinning mucus secretions for easier expulsion
Theraflu comes in powder form for mixing with hot water, creating a medicated drink that provides symptom relief for 4-6 hours. The hot liquid format helps soothe throat irritation while delivering the active ingredients into the bloodstream.
Safety Concerns for Nursing Mothers
Nursing mothers require specific guidance when taking Theraflu due to its multiple active ingredients that can pass through breast milk. The safety profile varies depending on the specific formulation and ingredients present.
Active Ingredients in Theraflu
The primary components in Theraflu formulations include acetaminophen, dextromethorphan HBr, and phenylephrine HCl. Acetaminophen transfers into breast milk at low levels, with less than 3.6% of the maternal dose reaching the infant. Dextromethorphan appears in breast milk in minimal amounts, though exact transfer rates remain under study. Phenylephrine poses particular concerns due to its potential to decrease milk production through vasoconstriction.
| Ingredient | Transfer Rate to Breast Milk | Risk Level |
|---|---|---|
| Acetaminophen | <3.6% | Low |
| Dextromethorphan | Minimal | Low-Moderate |
| Phenylephrine | Variable | Moderate |
- Changes in sleeping patterns or alertness
- Differences in feeding frequency or duration
- Variations in typical behavior or mood
- Decreased wet diapers or changes in urine output
- Signs of allergic reactions or skin changes
Alternative Cold and Flu Remedies While Breastfeeding
Nursing mothers have multiple safe options to manage cold and flu symptoms without using Theraflu. These alternatives include both natural remedies and specific over-the-counter medications approved for use during breastfeeding.
Natural Treatment Options
- Steam inhalation with plain water or saline solution helps clear nasal congestion
- Honey mixed with warm water soothes sore throats (avoid honey for babies under 12 months)
- Saline nasal sprays reduce congestion without medication
- Hot showers provide temporary congestion relief through steam therapy
- Salt water gargles (1/4 teaspoon salt in 8 oz warm water) ease throat discomfort
- Rest increases the body’s natural healing abilities
- Increased fluid intake prevents dehydration from illness
- Vitamin C rich foods boost immune function:
- Citrus fruits
- Bell peppers
- Leafy greens
Safe Over-the-Counter Medications
The following medications received approval from lactation specialists for use during breastfeeding:
| Medication Type | Safe Options | Primary Use |
|---|---|---|
| Pain relievers | Acetaminophen (Tylenol) | Fever & pain |
| Decongestants | Saline nasal sprays | Congestion |
| Cough suppressants | Dextromethorphan alone | Dry cough |
| Expectorants | Guaifenesin | Chest congestion |
| Antihistamines | Loratadine (Claritin) | Allergies & runny nose |
- Choose single ingredient products
- Take medications immediately after nursing
- Monitor infant for unusual symptoms
- Consult healthcare providers about specific dosing
How to Minimize Medication Transfer Through Breast Milk
Timing medication intake strategically reduces the amount of drug transfer to breast milk. Nursing mothers benefit from taking medications immediately after a feeding session when milk levels are lowest.
Optimal Timing Strategies
- Take medications right after nursing to maximize the time before the next feeding
- Schedule longer breaks between nighttime feedings to allow medication processing
- Document feeding times to maintain consistent medication intervals
- Monitor baby’s feeding patterns to identify optimal medication windows
Dosage Management
- Start with the lowest effective dose
- Space multiple doses evenly throughout the day
- Track medication timing using a digital reminder system
- Maintain 2 to 3 hour gaps between medication intake and nursing
- Express milk before taking medication to create an emergency supply
- Stay hydrated to maintain healthy milk production
- Store expressed milk from medication free periods as backup
- Monitor milk supply levels when using decongestants
| Medication Timing | Recommended Gap Before Next Feed |
|---|---|
| Morning Dose | 2-3 hours |
| Afternoon Dose | 2-3 hours |
| Evening Dose | 3-4 hours |
| Night Dose | 4-6 hours |
These strategies optimize medication effectiveness while protecting infant exposure through breast milk. Each nursing mother’s situation remains unique, requiring individual assessment of symptoms, medication needs and feeding schedules.
When to Contact Your Healthcare Provider
Contact a healthcare provider immediately if any of these symptoms occur while taking Theraflu during breastfeeding:
In the nursing mother:

- Displays unusual drowsiness or difficulty waking for feeds
- Feeds less than 6 times in 24 hours

- Exhibits changes in breathing patterns or wheezing
- Develops diarrhea vomiting or excessive fussiness
Medical attention becomes essential when cold symptoms persist beyond these timeframes:
- Fever lasting more than 3 days
- Cough continuing beyond 10 days
- Congestion remaining after 14 days
- Headaches worsening rather than improving
