Making an Appointment

We thank you for visiting our site. If you are ready to make an appointment to see Dr. Vivek Rao, or if you are still undecided and have questions for us, please give us a call at (432) 333-3300.

When scheduling your appointment, please have your insurance card handy. We will need your group number and policy number.

Allergy Testing

If you are interested in having allergy testing done, please note that certain medications (such as antihistamines) may interfere with testing. In order for testing to be done, you will need to stop antihistamines at least 5 days prior to your appointment. These include Alavert, Allegra, Astelin, Astepro, Azelastine, Benadryl, Chlorpheniramine, Chlortrimeton, Clarinex, Claritin, Dymista, Fexofenadine, Levocetirizine, Loratadine, Olopatadine, Pataday, Patanol, Pazeo, Promethazine (found in certain cough and nausea medications), Xyzal, Zyrtec, and some types of pain medications that also treat allergy and cold symptoms (Advil Allergy, Advil PM, Tylenol Allergy, Tylenol PM, etc.).

If you have received steroid injections or taken oral steroids (prednisone, methylprednisolone, Medrol, etc.) within the past 28 days, please check with us, as they may also affect test results. 

Let us know if you are taking a beta blocker, as this can sometimes make it unsafe to do allergy testing. Beta blockers are blood pressure medications that slow the heart rate down; they can also sometimes be used to treat migraines, tremors, and glaucoma. Examples of beta blockers include Atenolol, Carvedilol, Metoprolol, Propranolol, and Timolol. If you are on a beta blocker, you will need to get permission from the prescribing physician to stop it 3 days prior to testing. 

If you are taking an older acid reflux medication such as Cimetidine, Famotidine, Pepcid, Ranitidine, Tagamet, or Zantac, it will need to be stopped 2 days prior to allergy testing. Proton pump inhibitors like Nexium, Omeprazole, and Prilosec are OK to take.

There are a few other medications that can also affect testing. In particular, certain types of antidepressants and anti-anxiety medications can affect results. However, these medications cannot be stopped suddenly. Call us with the name of the medication in question, and we can let you know if it will interfere with testing.

Keep in mind that we will not be able to do allergy testing in individuals with poorly controlled asthma (we likely would  postpone testing until the asthma is first brought under control). All asthma inhalers (even steroid inhalers) are OK to take and therefore should not be stopped. Singulair (Montelukast) is also OK to take prior to testing. 

If you would like allergy testing during your initial visit, please call and let the staff know prior to your visit. Please do not stop any of your prescription medications or daily over-the-counter medications without getting permission from the healthcare provider who told you to take them. Also, feel free to give us a list of your medications beforehand if you would like to make sure none of them will affect allergy testing. 

On the Day of Your Visit

Things to Bring

We ask that you bring your current insurance card(s) and either a driver license or other government-issued photo I.D. with you on the day of your appointment. Children younger than 18 years must be accompanied by either a parent or legal guardian who can provide proof of guardianship. Please do not forget to bring your completed forms (Patient Information, Medical History Form, and Receipt of Notice of Privacy Practices).


We are located in Suite 300 of the Odessa Medical Clinic building, which is on the northeast corner of 5th Street and Adams Ave., across the street from Odessa Regional Medical Center.


Parking is available in the lot in front of the Odessa Medical Clinic building. However, please make sure you do not forget to print out a parking permit (see above) and place it on your dashboard near your steering wheel. Most of the parking lots near the hospital are closely monitored, and vehicles without parking permits may be towed.

When to Arrive

If you have already completed the forms listed above, please arrive 15 minutes prior to your scheduled appointment to complete a few additional forms.

If you are unable to complete the forms beforehand, please plan to arrive at least 30 minutes prior to the appointment.


Please be prepared to pay your portion at each office visit. In some cases, this will be a co-payment, which is normally indicated on your insurance card. In other cases, it may be a co-insurance. Sometimes, it may mean that you are responsible for the full amount until the deductible is met. If you are unsure, we encourage you to contact your insurance beforehand to confirm insurance benefits. We will also try to do the same as a courtesy to you, but we still strongly encourage you to contact your insurance yourself to verify coverage.

For your convenience, our office accepts checks, cash, Visa, MasterCard, and Discover.

Cancellations and No-Shows

We will make every effort to accommodate your scheduling needs. In return, we ask that you help us by keeping your scheduled appointment or by notifying us at least 24 hours in advance if you need to cancel. There will be a no-show fee of $25.00 if you fail to keep your appointment and do not provide us at least 24 hours notice that you will not be able to come.

We appreciate your understanding and cooperation with this policy and look forward to being of service to you and your family.
