We found no known interaction between Alkaline Diet and Chlorpheniramine Maleate, Dextromethorphan Hydrobromide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Alkaline Diet and Chlorpheniramine Maleate, Dextromethorphan Hydrobromide
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Chlorpheniramine Maleate, Dextromethorphan Hydrobromide and Alkaline Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Alkaline Diet alongside specific medications may be limited.
Worth understanding: our licensed dataset holds no drug-interaction record for Alkaline Diet at all — not against Chlorpheniramine Maleate, Dextromethorphan Hydrobromide, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
Alkaline Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Chlorpheniramine Maleate, Dextromethorphan Hydrobromide page
“Grapefruit is the interaction I would flag first for anyone taking chlorpheniramine with dextromethorphan (Coricidin HBP Cough & Cold). It blocks the enzyme that clears these ingredients, so levels and side effects can climb.”

Where does our data come from?

- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Alkaline Diet reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The Alkaline Diet and Chlorpheniramine Maleate, Dextromethorphan Hydrobromide records this page draws on were last updated June 22, 2026.

About Alkaline Diet
What is Alkaline Diet?
- General wellness
- Bone health
- Weight management
- Kidney stone prevention
- Reducing inflammation
The alkaline diet encourages eating more fruits and vegetables while cutting back on meat, dairy, and processed foods, which is generally healthy. However, the idea that food can meaningfully change your blood's pH is not supported by science, since your body tightly controls its own pH. Most benefits people see likely come from simply eating more whole plant foods.
Dietary pattern emphasizing fruits, vegetables, legumes, and limiting meat, dairy, and processed foods
An interaction check asks whether these two react with each other — it does not ask whether Alkaline Diet is a good idea for someone in your situation. Here is what our Alkaline Diet record says about it on its own.
Alkaline Diet: dosing
There is no standard 'dose' for the alkaline diet because it is an eating pattern, not a pill. In general, it means filling more of your plate with fruits, vegetables, and legumes while cutting back on processed foods, added sugar, and excess meat.If you choose to follow it, aim for a balanced version that still includes enough protein, calcium, and other key nutrients. A registered dietitian or your pharmacist can help you adjust the plan safely, especially if you have a health condition or take medications.
