Instillagel

Lidocaine Hydrochloride, the active ingredient in Instillagel, is a local anesthetic presented as a gel for urethral use. It provides topical anesthesia for diagnostic or therapeutic procedures involving the urethra and helps relieve discomfort during catheterization.

GNH USA supplies Instillagel as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

Instillagel, a lidocaine‑based local anesthetic, is used for urogenital procedures that require urethral anesthesia.

Urethral anesthesia for diagnostic procedures: provides pain relief during cystoscopy or uroflowmetry. Therapeutic urethral procedures: facilitates comfortable performance of urethral dilatation or surgery. Catheterization discomfort relief: reduces pain and spasm when inserting urinary catheters. Post‑procedure urethral care: helps manage pain after urological interventions.

Instillagel may cause local and systemic adverse reactions.

Common Side Effects: - Burning or stinging sensation at the application site. - Mild irritation or redness of the urethral mucosa. - Transient numbness that resolves after the gel is cleared.

Serious or Rare Side Effects: - Allergic reactions such as rash, urticaria, or angioedema. - Systemic lidocaine toxicity presenting as dizziness, seizures, or cardiac arrhythmia. - Severe local tissue necrosis if applied excessively or left in situ for prolonged periods.

Before using Instillagel, consider the following safety measures.

Allergy assessment: confirm no known hypersensitivity to lidocaine or amide‑type anesthetics. Pregnancy and lactation: use only if the potential benefit justifies the potential risk; data are limited. Age considerations: exercise caution in paediatric or geriatric patients due to altered absorption. Concurrent local anesthetics: avoid exceeding the total recommended lidocaine dose. Urethral pathology: do not use in the presence of severe infection, ulceration, or trauma. Store at room temperature below 25°C: keep in the original container, protect from moisture and direct sunlight.

Instillagel can interact with other medicines; monitor the following.

Major Interactions (Avoid): - Class I antiarrhythmic agents (e.g., quinidine, procainamide): may increase systemic lidocaine levels. - Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): can raise lidocaine exposure. - Concurrent use of other local anesthetics: risk of cumulative toxicity.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may enhance cardiac depressant effects of lidocaine. - Diuretics such as furosemide: may alter lidocaine clearance. - Anticonvulsants: may affect seizure threshold when lidocaine systemic absorption occurs.
