Instillagel (Chlorhexidine/Lidocaine) is used for adults and children over 2 years old when putting a tube or instrument into the urethra (the canal leading to your bladder). Instillagel is a gel that is used to numb the parts of the body it is applied to (local anaesthetic). Instillagel is used during insertion of a medical instrument into the urethra (cystoscopy); during insertion of a catheter; during exploration by sound and other operations in the urethra. Instillagel contains a local anaesthetic (lidocaine) to prevent pain and an antiseptic (chlorhexidine) to reduce the risk of infection, while lubricating to make the process smooth. It may also be used in your throat, bladder, vagina, rectum or colon. This makes it easier for your doctor to look inside these parts of your body without causing you discomfort. The Instillagel syringe is for single use only.
Canadian Pharmacy King currently offers the brand Instillagel from Canada by Pendopharm Pharmascience. Instillagel 10 x 11ml Prefilled Syringes and Instillagel 10 x 6ml Prefilled Syringes are available in the dosage of 0.05 %/2%. The generic alternative is currently unavailable.
Like all medicines, this medicine can cause side effects, although not everybody gets them. You might feel a slight stinging just after the gel is used, but this stops as soon as the anaesthetic starts to work. Most people find that there are no problems after the gel has been used, but of course there may be some soreness when the effect of the local anaesthetic has worn off. Possible side effects include serious allergic reaction that might cause difficulty with breathing or dizziness; low blood pressure (hypotension); changes in heart rate (bradycardia); fits (convulsions). It is not known how frequently these side effects occur.
The gel should not be used if you know that you are allergic or hypersensitive to these or any of the other ingredients, or to any other “-caine” type anaesthetics. Please inform the healthcare professional who is going to use the gel if this applies to you. Instillagel is for topical use only and is not to be injected. Before using Instillagel, tell your doctor if you have heart problems; liver problems; kidney problems; you are epileptic; you have ever had an unusual or allergic reaction to Instillagel, to another lidocaine or other medicine ending in “caine”; there is an infection, cut or rash at or near the area where you wish to apply Instillagel; you are in severe shock; have malignant hyperthermia (a hereditary condition). Tell you health care professional if you are pregnant, or breastfeeding. The gel should not be used if it is going to be in contact with damaged membranes. Drugs that may interact with Instillagel include some other local anaesthetics; medicines used for treating irregular heartbeats; a medicine used for heart problems; an antibiotic and a medicine used for depression or obsessive compulsive disorder.
