Can smoking marijuana affect my H. pylori medication?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello, Doctor,

I am currently taking Pylera to treat H. pylori infection. Before taking, I smoke marijuana to help with the nausea. The nausea has gotten worse on this medication, which I know is normal, but I wanted to know if it was safe to smoke marijuana while on the Pylera?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Some precautions that need to be kept in mind before using this medication are

  1. Tell your doctor or pharmacist your medical history, especially of: kidney disease, liver disease, blood disorders, brain/spinal cord disorders, seizures, trouble swallowing, and esophagus problems.

  2. This medicine may make you dizzy. Do not drive, operate machinery, or engage in any activity that requires alertness until you are sure you can perform it safely.

  3. This medicine contains drugs that may pass into breast milk and could have undesirable effects on a nursing infant. Therefore, breastfeeding is not recommended while using this drug. Consult your doctor before breastfeeding.

Your gastroesophageal reflux disorder (GERD) will get aggravated by the use of marijuana. You should also avoid alcoholic beverages and products containing propylene glycol while taking this medicine and for at least 3 days after finishing this product because it may cause the following issues,

  1. Severe stomach upset.

  2. Cramps.

  3. Nausea.

  4. Vomiting.

  5. Headache.

  6. Flushing.

I hope this information helps you.

Feel free to ask further queries.

Thank you.
