How long has this been bothering you?
Do you have any chronic medical problems?
Are you taking any chronic medicines?
it has been about 4 days. I don't have any chronic medical problems. I recently had yeast infection, so I took the pink peel twice. 2nd one was after 3 days of the first one.
Thank you for the additional information.
There are several possible causes of a dry mouth. The bitter taste is non-specific, as anything that causes a dry mouth can distort taste. When the dry mouth is of short duration, there should be consideration of any acute illness that can cause dehydration, even though you are drinking plenty of water. The most common cause would be a viral infection. There are also chronic conditions that can cause dry mouth by affecting hydration status, such as diabetes, but these would be more of a concern if the problem is long-standing. Dry mouth can also be due to diseases that affect the salivary glands, such as inflammation or infection. There also can be inflammation or irritation of the mouth associated with acid reflux. Dry mouth is also a common side effect of many different medicines, but is not reported as a typical side effect from Diflucan. Tobacco and caffeine can also exacerbate any of the above conditions and contribute to a dry mouth. Ultimately, it would require an appropriate medical evaluation to determine the exact cause, although there are some interventions that you can try at home. It is appropriate to increase fluid intake, as you are doing. It is important to stop tobacco or caffeine, if being used. It also may help to suck on hard candy or chew gum to stimulate saliva production, although sugarless versions would be preferable. If you suspect that you may have acid reflux, then a medicine to control acid may be helpful, such as Prevacid or Prilosec.
Since it has only been present for 4 days, it would be reasonable to give it a few more days. If it persists, it would be appropriate to first see your primary care physician.
No, but there is no definite threshold at which you should see your doctor. In part it depends upon the severity of the symptoms and the response to other interventions. If it is more bothersome and does not help to be using any of the interventions, then it would be appropriate to be seen sooner.
