What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Paracervical block- Lidocaine without epinephrineDrug
1-2 cc of Lidocaine at the tenaculum site on the cervix at 12 o-clock will be injected after pain scale #1 is completed. Pain scale #2 will be done then 3 cc of 1% lidocaine at 4 and 8 o'clock position of the cervix will be administered. The IUD insertion or EMB will be performed nd pain scale #3 will be done.
Benzocaine Gel applied to the cervixDrug
After pain scale #1 is performed , topical benzocaine will be applied to the cervix with Procto swabs and this will be allowed to remain on cervix for 203 minutes. Then Betadine will be applied to the cervix and surrounding vaginal tissue followed by pain scale #2. IUD insertion or EMB will be done followed by pain scale #3.
Hydroxyzine HydrochlorideDrug
Preprocedure, a GAD 7 scoring will be performed to determine level of anxiety. If > 10 indicating Moderate anxiety, participants will be offered pretreatment with Anxiolytic (Hydroxyzine 25mg) approximately 15-20 mins before procedure. If this is done at the preceding visit, participants will be sent home with a prescription for hydroxyzine to be taken 10-15 mins before the procedure when participants are brought back for procedure visit.

|---|---|---|
| Paracervical block- Lidocaine without epinephrine with Hydroxyzine hydrochloride if needed | Experimental | Not described Receives: Drug: Paracervical block- Lidocaine without epinephrine; Drug: Hydroxyzine Hydrochloride |

| No analgesia with Hydroxyzine hydrochloride if needed | Experimental | Not described Receives: Drug: Hydroxyzine Hydrochloride |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in pain perception during IUD insertion as assessed by the Faces Pain Visual Analogue Scale (VAS)
VAS is scored from 1-10, higher score indicating greater pain
Measured: baseline (with the speculum in place before pain management procedures), after tenaculum placement (but before IUD placement or EMB) and immediately after IUD insertion or EMB.
Secondary outcomes (1)
Change in anxiety as assessed by the General Anxiety Disorder-7 (GAD-7) scale
Measured: baseline, and after taking Hydroxyzine about 15-30 mins before procedure

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Paracervical block- Lidocaine without epinephrine, Benzocaine Gel applied to the cervix and Hydroxyzine Hydrochloride in people with Anxiety and Pain, run by The University of Texas Health Science Center, Houston at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 22 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Pamela Berens, MD ((713) 500-6471, Pamela.D.Berens@uth.tmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in pain perception during IUD insertion as assessed by the Faces Pain Visual Analogue Scale (VAS) (time frame: baseline (with the speculum in place before pain management procedures), after tenaculum placement (but before IUD placement or EMB) and immediately after IUD insertion or EMB.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2025; AzTrials last refreshed its copy on 8 Nov 2026.
