Unsure without : Knowing what other medication you are speaking about. Benadryl (diphenhydramine) is generally safe with most medications, but to be cautious, can not be sure without knowing what medication it is.

Be Careful: You can, but be careful. Patients with heart failure will usually be on a lot of medications and the Benadryl (diphenhydramine) may interact with them. Benadryl (diphenhydramine) will make you sleepy and may affect your breathing. This could make your symptoms worse.
