Question: 69 year old male - for two months I have had excess mucus in my throat. i particularly notice it at night and often start swallowing to try to get rid of the mucus - very disruptive of sleep. I have been taking Mucinex (2-4 tablets/day) for the last two weeks - it does help. But I still catch myself trying to clear my throat often. I am a non smoker. The back of my throat is a bit sore but not like a sore throat. I have experienced some heartburn over the last 1 1/2 years - it usually occurs in a.m. about an hour after breakfast if I get real active. I take an antacid tablet and it goes away. ???????

Questions to clarify

Detailed Answer:
Hello XXXX,

Some people have acid reflux that is "silent" - where they don't feel the acid coming up, and it can cause throat clearing types of symptoms.

What is the antacid tablet that you are taking - name, dosage, and how often you take it?

The antacid tablet I take is Equaline extra strength 750 mg. When I use it I take two tablets. The frequency is sporadic - maybe 8 tablets over a months time.
The mucus is not as much of a problem during the day when I am on my feet. When I sit down and especially lie down is when I am bothered the most.
* If the mucus is caused by acid reflux would taking the antacid tablet on a
regular schedule be more effective?
* Would you recommend another type/brand of antacid?
* My wife feels that limiting food intake after supper could help. Your opinion?
* I am 5'9" and weigh 185 pounds. Could losing weight help?
* What are other causes of excess mucus that could be causing this?
* The sore back of the tongue (back edges)/scratchy throat - Could that be
caused by the acid?
Thank you for any suggestions.

Detailed Answer:
Hello XXXX,

Equaline Extra Strength antacid tablets are calcium carbonate which means that it interacts with the acid to neutralize it. For some people that is enough, but it sounds like it is not enough for you.

For people with acid reflux, which it does sound very likely that you have, the next step in medication is either an H2 blocker which reduces acid or the popular proton pump inhibitors (PPIs). Both have versions sold over the counter. I will tell you I am not a big fan of PPIs except for severe cases, because they tend to cause rebound for some people (increased acid production on discontinuation of the medicine) and have more side effects than H2 blockers.

So - an H2 blocker you can get without prescription is Zantac. I recommend 150 mg twice a day (or if it is easier, 300 mg once a day). Zantac (ranitidine) will reduce acid by about 70% which can allow your stomach and esophagus to heal. You may need to take it up to 6 weeks. You will probably notice some benefit in the first week.

While taking that, best to skip the antacid tablets.

Other recommendations for dealing with acid reflux:
1. Certain foods may set it off more and that can vary from one person to the next, but in general, tomatoes, citrus/acidic foods and drinks, spicy, greasy/fried foods, caffeine, sodas, chocolate can cause more trouble.
2. Avoid or decrease alcohol.
3. No smoking! Tobacco in any form can lower the pressure of the lower esophageal sphincter (which you don't want) and increase acid production too.
4. No mint. I know this sounds strange but mint also relaxes the lower esophageal sphincter allowing acid up.
5. Losing weight gradually can help.
6. Some people get benefit from a supplement called DGL (deglycyrrhizerinated licorice) but I don't want to recommend it without knowing what other meds you might be on.
7. Eating smaller amounts at a time is helpful. If the stomach has more in it, it has more pressure to send acid up the esophagus. Also, stomach distention increases acid production.
8. Your wife's suggestion of no eating before bed is very good. Don't lie down within 2-3 hours of eating.
9. Given that this increases with lying down, consider elevating the posts under the head of your bed. They sell blocks for this at hardware stores and pharmacies because night time acid reflux is a common problem.

The irritated throat and back of the tongue can definitely be from acid reflux. But it can also be from post nasal drainage if you have allergies or an infection. Allergies tend to be worse at night too, so that is a consideration. Both can increase mucus in the throat. Allergies and infections by causing post nasal drainage. With acid reflux, the feeling is usually more of a burning type of sensation. And increased symptoms from sitting is more likely to go with acid reflux (because of increased pressure on the stomach) than with allergies.

I hope I have answered your questions. If there is an area I can clarify further, please do let me know.

Thank you so much for your response. I will try the zantac and some of the other suggestions. I am sending a list of my prescription medications in case any would react negatively with the zantac:
* paroxetine HCL - 10 mg once daily
* pravastatin sodium - 40 mg tablet once daily
* lisinopril - 20 mg tablet twice daily
* triamterene-HCTZ - 37.5-25 mg tablet once daily
* travatan and dorzolamide-timolol eye drops for glaucoma

Thank you again for your suggestions.

Detailed Answer:

I looked on Lexicomp drug interactions and entered ranitidine (the generic for Zantac) and all of your current medications. There were no interactions identified between ranitidine with the other medications.

Good luck - I hope you are feeling better soon.

Hi. My Daughter has a cough and rash on her forehead (tiny bumps) no fever, no itch no pain no other symptoms. Plays well, eats well and sleeps well. She has been taking Claritin for spring allergies and started on mucinex yesterday to keep her cough loose. I m puzzled by the tiny bumps on her forehead. The community pool just opened this past week so could it be the pool water?

Hi, I'm 20 years old and experiencing severely sharp pain in my ear that travels down to my neck and across my face. I can't hear in that ear either. This began about 6 days ago after getting a thorough ear cleaning from my ENT. I went to the emergency room 2 nights ago and the doctor there could not treat me. Although he did give me ear drops, mucinex D, amoxycillin and pain medicine. None of it has helped at all. Is there any home remedy to help alleviate the pain until I can go back to my ENT tomorrow? Do I have an ear infection and was it caused by the deep cleaning?

I have had a low grade fever (99.1-100.3) for 3 days, accompanied with a cough that feels like it burns in the upper part of my chest when I do so. Just today I noticed a white coating on my tongue. I ve just been taking OTC Mucinex D and iburophen off and on. Should I be concerned about the white tongue?
