Following a professional Zantac 360 dosage chart is the most effective way to manage acid reflux and heartburn without risking long-term side effects. As a licensed pharmacist, I recommend using this chart to ensure you are taking the correct strength of famotidine for your specific symptoms.
Zantac 360 Dosage Chart for Adults
Zantac 360 (which now contains Famotidine) is an H2 blocker that decreases stomach acid. Therefore, timing is everything: for the best results, take it 15 to 60 minutes before eating food that causes heartburn.
| User Group | Single Dose | When to Take | Max Daily Dose |
| Adults (12+ years) | 20 mg (1 tablet) | 30-60 min before breakfast | 2 tablets (40 mg) |
Pharmacist’s Note: Do not exceed 2 tablets in a 24-hour period.

Pharmacist Tip: Prevention vs. Treatment
Unlike antacids that work instantly but wear off fast, Zantac 360 prevents acid before it starts. If you suffer from frequent, chronic heartburn, you may need a different class of medication. Follow my guide on PPIs (Proton Pump Inhibitors) to see if they are a better fit for your condition.
Important: Zantac 360 vs. Pepcid
It is crucial to note that Zantac 360 is identical to Pepcid; both contain the same active molecule, Famotidine. Consequently, you must be careful not to take them together to avoid accidental overdose. Read my Pepcid Dosage Guide here to compare strengths and formulations.
Acute Gastritis & Reflux Protocol: Zantac, Aloe & Gaviscon
If you are suffering from acute gastritis or severe burning, a single medication might not be enough. As a pharmacist, I suggest this integrated protocol to coat the stomach lining while reducing acid production.
Gastritis & Reflux Protocol Table
| Time of Day | Medication / Supplement | Dosage & Timing |
| Early Morning | Zantac 360 (Famotidine) | 1 tablet 60 min before breakfast |
| After Breakfast | Aloe Vera Juice | 2 oz (60ml) immediately after eating |
| Before Lunch | NOW Super Enzymes | 1 capsule 10-15 min before eating |
| After Lunch | Gaviscon Double Action | 2 tablets (chewed) 30 min after eating |
| Before Dinner | NOW Super Enzymes | 1 capsule 10-15 min before eating |
| After Dinner | Gaviscon Double Action | 2 tablets (chewed) 30 min after eating |
| Bedtime | Aloe Vera Juice | 2 oz (60ml) right before sleeping |

The European Secret: Hyaluronic Acid for Acid Reflux
In Europe, doctors often prescribe products based on Hyaluronic Acid and Chondroitin Sulfate, such as Esoxx One, to physically repair the esophageal mucosa. This approach is gaining popularity in the USA for those who don’t want to rely solely on drugs. Read my full article on Hyaluronic Acid for Acid Reflux to see how it compares to standard treatments.
