Instillido

Lidocaine Hydrochloride, the active ingredient in Instillido, is a local anesthetic presented as a sterile solution for urethral use. It provides temporary loss of sensation to facilitate diagnostic or therapeutic procedures involving the urethra.

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

Instillido, a urethral local anesthetic, is employed to numb the urethral mucosa during various urological interventions. - Cystoscopy: provides local numbness to facilitate examination of the bladder and urethra. - Catheter insertion: reduces discomfort during placement of urinary catheters. - Transurethral procedures: enables pain‑free therapeutic interventions such as resection or dilation.

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

Common Side Effects: - Burning or stinging sensation at the application site - Mild urethral irritation or discomfort - Transient numbness lasting several minutes - Urinary urgency or frequency - Light‑headedness or mild headache

Serious or Rare Side Effects: - Allergic reaction including anaphylaxis - Severe hypotension or cardiovascular collapse - Cardiac arrhythmias such as ventricular tachycardia - Methemoglobinemia leading to cyanosis - Seizures or central nervous system toxicity - Persistent numbness beyond the expected duration

Before using Instillido, several safety considerations should be observed. - Assess allergy: confirm the patient has no known hypersensitivity to lidocaine or related amide anesthetics. - Use minimal effective volume: limit exposure to the urethral mucosa to reduce systemic absorption. - Monitor vital signs: observe for hypotension, bradycardia, or arrhythmias during and after administration. - Avoid concurrent systemic local anesthetics: concurrent use may increase the risk of cumulative toxicity. - Pregnancy and lactation: use only if the anticipated benefit outweighs potential risk to the fetus or infant. - Store at room temperature: keep in the original container, protect from moisture and light.

Instillido can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Class I antiarrhythmic drugs (e.g., quinidine, procainamide): additive cardiotoxicity risk. - Beta‑blockers (e.g., propranolol): may enhance lidocaine’s cardiac depressant effects. - Strong CYP3A4 inhibitors (e.g., ketoconazole): increase systemic lidocaine exposure.

Moderate Interactions (Monitor Closely): - Other local anesthetics: cumulative toxicity potential. - Epinephrine: may alter lidocaine absorption and cardiovascular response. - Diuretics (e.g., furosemide): may affect plasma protein binding and increase free drug levels.
