There is no interaction between Sudafed PE (phenylephrine) and Amoxicillin-Clavulanate (Augmentin), so they can be taken safely together.


Amoxicillin-Clavulanate

According to the prescribing information, Amox-Clav is an antibiotic containing a penicillin that is used for a variety of infections, including sinus, skin, urinary tract, and lower respiratory infections.


Common Side Effects

  • Diarrhea
  • Nausea
  • Skin rash
  • Itching
  • Vomiting
  • Vaginitis


Drug Interactions

  • Warfarin: INR monitoring recommended since penicillin antibiotics may increase the INR and risk of bleeding when on warfarin
  • Probenecid: may decrease excretion of antibiotic and cause increased concentrations of Amox-Clav; not recommended together
  • Allopurinol: increases potential for developing rash
  • Oral contraceptives (birth control): may reduce the effectiveness of oral contraceptives through decreasing absorption
    • Another form of contraception should be used along with the oral contraceptive to reduce risk of pregnancy


Warnings and Cautions

  • Hypersensitivity reactions (allergic reactions) may occur and may be severe
    • Tell your healthcare provider and pharmacist if you have a history of allergic reaction to beta-lactam antibiotics (penicillins, cephalosporins) before use
  • Hepatitis / cholestatic jaundice has been reported and hepatic function should be considered before use
  • Clostridium difficile (C. diff) diarrhea may occur and patients should make sure to stay hydrated if experiencing diarrhea and tell a healthcare provider if having severe or bloody diarrhea
  • Amox-Clav chewable tablets and suspensions contain phenylalanine and should not be used in phenylketonurics


Contraindications

  • Hypersensitivity to any of the ingredients or penicillins
  • Hepatic dysfunction / cholestatic jaundice


Other

  • Suspensions of this medication should be refrigerated and if there is any suspension left over after the recommended course is finished, it should be discarded
  • Finish the whole course of antibiotics unless told otherwise by a healthcare professional, as unfinished antibiotic therapy can cause bacterial resistance
  • Although Amox-Clav can be taken with or without food, taking the antibiotic with food may help decrease stomach upset


Sudafed PE

According to the prescribing information, Sudafed PE is a decongestant used to relieve congestion and pressure caused by allergies or colds.


Side Effects

  • Talk to a healthcare professional these symptoms persist or are severe:
    • Dizziness
    • Insomnia
    • Nervousness
    • Increased blood pressure


Warnings and Cautions

  • Consult a healthcare provider before taking Sudafed PE or other products containing phenylephrine or pseudoephedrine if you have:
    • Heart disease
    • High blood pressure
    • Diabetes
    • Thyroid problems
    • Enlarged prostate gland and trouble urinating
  • Do not use if you are taking a monoamine oxidase inhibitor (MAOI), as it can cause a significant and potentially dangerous increase in blood pressure
    • Examples of MAOIs: rasagiline (Azilect), selegiline (Eldepryl, Zelapar), isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate)
  • Certain forms of phenylephrine that contain aspartame contain phenylalanine and should not be used in phenylketonurics


Other

  • Do not take more than 6 tablets of the phenylephrine 10 mg (60 mg) in 24 hours
  • If symptoms do not resolve within 7 days, stop taking Sudafed PE and see a healthcare professional
  • Products with phenylephrine are not approved for children less than 4 years of age; however, a healthcare provider should be consulted before use in children less than 12 years of age
