Brief Answer:
Sounds like something needs to be DIAGNOSED

Detailed Answer:
Thank you for your question and I'm sorry you are feeling under the weather.

Dyazide is a diuretic and causes loss of body fluids which is a way to treat high blood pressure (hypertension) or abnormal retention of water such as occurs in congestive heart failure, kidney failure, lymphedema in the extremities for other reasons. It is not a medication for treating dizziness or nausea unless of course those symptoms are believed to be a consequence to acute rises in blood pressure oar acute decompensations in heart or kidney function.

Phenergan is a medication to treat nausea but unless the root problem is known and being addressed then, these types of medications wouldn't be expected to help very much, if at all.

Therefore, if you are having troubling symptoms as you describe which have not abated and you do not yet know exactly why these symptoms are present. And if especially, you have any type of fever or infectious condition associated with your dizziness and nausea then, I would recommend you be seen at an URGENT CARE center or call your doctor's office for advice on what to do tonight.

Also, be aware that Dyazide, cardizem, lipitor, and lisinopril can all increase symptoms of dizziness and nausea due to drug to drug interactions. Therefore, if any of those medications are new to you or if the dosage of any of these drugs were recently changed in the last 1-2 weeks then, your symptoms may be side effects of those changes or interactions of the drugs.

It is not possible for a doctor who has not had the opportunity of getting to know a patient to say with certainty whether or not they should go to an ER. It is to the discretion of the patient to decide the severity of their own condition to warrant or not such a visit if no other options are available.

However, the rule of thumb with respect to nausea, vomiting, and/or inability to hold food/liquids down is that if primary treatments do not solve the problem in 24-48 hrs. despite best efforts....it is clearly to the patient's benefit to be consulted immediately by a physician (ER or not) so that they do not fall behind the 8 ball. Issues of dehydration can go from bad to worse very quickly and without warning. Better to visit a facility where at least some fluids can be hung and infused than stay at home and battle with a problem not responding to best treatment.
