Advil, also known as ibuprofen, is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain and reduce fever. Erythromycin, on the other hand, is an antibiotic that is used to treat bacterial infections.

According to Drugs.com, there is a moderate interaction between erythromycin and ibuprofen, which is the active ingredient in Advil. This means that taking these two medications together may increase the risk of side effects such as stomach bleeding and gastrointestinal ulcers. Therefore, it is recommended to avoid taking them together unless advised by a healthcare professional.

Netdoctor states that erythromycin can interact with several medications, including NSAIDs like ibuprofen. The website advises patients to inform their doctor or pharmacist if they are taking any other medications, including over-the-counter medications, before taking erythromycin.

DrugPatentWatch provides information on the patent status of drugs, including Advil. While it does not provide information on drug interactions, it is still a useful resource for understanding the availability and legal status of medications.

In conclusion, based on the sources provided, it is not recommended to take Advil with erythromycin unless advised by a healthcare professional. Patients should inform their doctor or pharmacist of any medications they are taking before starting erythromycin treatment.
