From the Guidelines

If your cough worsens when lying down on day 4 of Augmentin therapy, contact your healthcare provider promptly to assess the need for a treatment adjustment or further evaluation. This symptom could indicate several possibilities: your infection may not be responding adequately to the antibiotic, you might be experiencing postnasal drip from the infection, or you could be developing acid reflux as a side effect of the medication 1. While waiting to speak with your doctor, try elevating your head and upper body with extra pillows when sleeping, stay well-hydrated, and consider using a humidifier in your bedroom. You might also try taking your Augmentin with food to reduce potential gastrointestinal irritation. It's essential to note that the current guidelines for managing acute cough due to suspected pneumonia or influenza suggest measuring C-reactive protein (CRP) to strengthen the diagnosis and exclusion of pneumonia 1. However, in your case, since you are already on Augmentin, the focus should be on assessing the response to the treatment and adjusting it as necessary. Given the potential severity of pneumonia and the importance of appropriate antibiotic treatment, as highlighted in the guidelines 1, it is crucial not to stop your antibiotic course without medical advice, as completing the full prescribed duration is vital for properly treating the underlying infection. A worsening cough, particularly when positional, warrants medical evaluation to determine if your treatment plan needs adjustment or if additional medications like cough suppressants or acid reducers might be beneficial. Key considerations include:

  • Monitoring for signs suggestive of pneumonia, such as fever, dyspnea, and pleural pain 1
  • The potential role of CRP in diagnosing pneumonia, although this may not be directly applicable if you are already undergoing treatment 1
  • The importance of adhering to the prescribed antibiotic regimen unless advised otherwise by a healthcare provider 1

From the Research

Cough Worsening with Laying Down on Day 4 of Augmentin Therapy

  • The worsening of cough with laying down on day 4 of Augmentin (amoxicillin/clavulanate) therapy may be related to the underlying infection being treated, as Augmentin is commonly used to treat community-acquired respiratory tract infections 2.
  • It is essential to note that cough is a common symptom of respiratory tract infections, and its worsening with laying down could be due to various factors, including postnasal drip or gastroesophageal reflux disease 3.
  • The treatment of pneumonia, a common cause of respiratory infection, typically involves antibiotics, and knowledge of local bacterial pathogens and their antibiotic susceptibility and resistance profiles is crucial for effective treatment 4.
  • In the case of Augmentin, it is a broad-spectrum antibacterial agent that has been used for over 20 years, with a high bacteriological and clinical efficacy in respiratory tract infections 2.
  • However, the emergence of resistant strains, such as Pseudomonas aeruginosa, may require alternative treatment options, including novel antibiotics or combination therapy 5.
  • It is also important to consider the properties and indications of oral amoxicillin and amoxicillin-clavulanic acid, as well as their potential side effects, when using Augmentin as empiric therapy 6.

Potential Causes and Next Steps

  • The worsening of cough with laying down on day 4 of Augmentin therapy may require further evaluation to determine the underlying cause, including chest radiography to rule out concerning infectious, inflammatory, or malignant thoracic conditions 3, 4.
  • Patients with refractory chronic cough may warrant referral to a pulmonologist or otolaryngologist, and may benefit from a trial of gabapentin, pregabalin, and/or speech therapy 3.
  • In children, cough is considered chronic if present for more than four weeks, and evaluation should focus initially on common etiologies, such as asthma, protracted bacterial bronchitis, and upper airway cough syndrome 3.
