Effectiveness

How Pepcid Ac Affects PatientsFamotidine helps to reduce the amount of acid in your stomach. It works quickly, with effects typically seen within an hour, and can last up to 12 hours. It is most effective when taken at the highest dose. Famotidine also reduces the amount of pepsin in the stomach, and blocks acid secretion triggered by food, caffeine, insulin, or pentagastrin.
How Pepcid Ac works in the bodyHistamine is a hormone that helps control the acid production of your stomach. It is released by special cells near your parietal cells, and is also triggered by acetylcholine and gastrin. Gastrin works on CCK2 receptors to cause the release of even more histamine. When histamine is released, it acts on H2 receptors and causes more acid to be produced. Famotidine works by blocking the effects of histamine, reducing the amount of acid produced in your stomach. This can help reduce symptoms of conditions that involve too much acid production, like ulcers.

Pepcid Ac Reviews: What are patients saying about Pepcid Ac?

Pepcid Ac for Indigestion
Pepcid AC Complete does a great job at stopping heartburn symptoms. It has an antacid for immediate relief and an H2 blocker for longer term relief, which together last for almost 24 hours. I have found that the only downside to taking it regularly is that I sometimes experience dizziness. This was even bad enough to wake me up from sleep on occasion, but cutting back on the Pepcid AC Complete stopped the problem.

Pepcid Ac for Inflammation of Esophagus from Backflow of Stomach Acid
Pepsid has really been a life-saver for me. I have an allergy to previcid, and it was giving me big problems with acid reflux. My doctor switched me over to pepsid and told me to use it every day. I don't use it every day because I've heard horror stories from friends about the other options out there-- they couldn't get off of them without a lot of pain.

Not only does Pepcid work quickly to reduce heartburn, but I've also noticed a reduction in my blood pressure. Could this be a contributing factor?

Pepcid Ac for Zollinger-Ellison Syndrome
I've been happy with the results of this treatment, but I am concerned that it may be a proton pump inhibitor (PPI). There have been reports of problems with this type of drug. Please advise if Pepcid AC is one of the drugs causing these problems.

Pepcid Ac for Stress Ulcer Prevention
I haven't been to the doctor yet, but lately have been experiencing acid indigestion that I think may be acid reflux. I have been taking it when the pain occurs, which takes about 10 minutes to start working. I am definitely going to try to take it in the morning and evening as another reviewer suggested.

Patient Q&A Section about pepcid ac

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What does Pepcid AC do to your stomach?

"It works by decreasing the amount of acid your stomach makes. It relieves symptoms of a cough that doesn't go away, stomach pain, heartburn, and difficulty swallowing. Famotidine belongs to a class of drugs known as H2 blockers. This medication is also available without a prescription."

Answered by AI

What are the side effects of Pepcid AC?

"Anxiety, skin problems, bloody stool, difficulty breathing, discouragement, fast heartbeat, feeling sad."

Answered by AI

What is the difference between PEPCID and Pepcid AC?

"There are two types of PEPCID AC; Original Strength and Maximum Strength. They both contain an H2 blocker that begins to work in 15-30 minutes. It helps control acid all day or all night. PEPCID Complete combines an H2 blocker with an antacid that starts neutralizing acid in your stomach in seconds. It works even faster than the other two."

Answered by AI

Is Pepcid AC and Zantac the same thing?

"PEPCID and ZANTAC are approved for the same use, but PEPCID contains Famotidine. ZANTAC contains Ranitidine, which is different from the other over-the-counter products."
