Instillido

Lidocaine Hydrochloride, the active ingredient in Instillido, is a local anesthetic presented as a sterile solution for urethral use. It provides temporary numbness to facilitate diagnostic or therapeutic procedures involving the urethra and reduces discomfort during catheterization. GNH USA supplies Instillido as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Instillido, a local anesthetic acting on peripheral nerves of the urethra, is employed for several urological procedures. - Urethral anesthesia for diagnostic or therapeutic procedures: provides localized numbness to enable painless examination or treatment. - Pain relief during catheterization: reduces discomfort associated with urinary catheter insertion. - Urethral anesthesia for transurethral interventions: facilitates patient comfort during endoscopic surgeries.

Instillido may cause a range of adverse reactions following urethral administration.

Common Side Effects: - Burning or stinging sensation at the application site - Transient local numbness lasting longer than the procedure - Mild urinary urgency or frequency - Mild headache - Dizziness or light‑headedness - Mild irritation or erythema of the urethral mucosa

Serious or Rare Side Effects: - Allergic reaction including rash, itching, or swelling - Severe hypotension or cardiovascular collapse - Methemoglobinemia - Cardiac arrhythmias - Seizures or central nervous system toxicity - Systemic lidocaine toxicity presenting as confusion or respiratory depression

Before using Instillido, consider the following safety measures. - Allergy assessment: confirm the patient has no known hypersensitivity to lidocaine or related amide anesthetics. - Dosage determination: follow the prescriber's specific instructions for volume and concentration. - Cardiac disease: use with caution in patients with existing cardiac conduction abnormalities. - Pregnancy and lactation: evaluate risk‑benefit ratio and consider alternative approaches when possible. - Systemic absorption: monitor for signs of toxicity, especially with large volumes or repeated applications. - Store at room temperature: keep in the original container, protect from light and moisture.

Lidocaine may interact with other medications, affecting its safety profile.

Major Interactions (Avoid): - Class I antiarrhythmics (e.g., quinidine, procainamide): can increase plasma lidocaine levels and risk toxicity. - Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may elevate systemic exposure.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may enhance lidocaine’s cardiac depressant effects. - Concurrent use of other local anesthetics: additive risk of systemic toxicity. - Diuretics: may alter lidocaine plasma concentration and clearance.
