Stilnox



There were instances in my clinical practice where I prescribed this drug to some of my patients. I first encountered this medication when I was rotating at the psychiatric ward during my clerkship. We give this to patients who have difficulty in getting sleep. It is a readily available drug in local pharmacies and as long as a physician has an S2 license, it can be easily prescribed.

I encountered this news article regarding it and I find it worth knowing, not just for doctors but for users as well.

The sleeping drug Stilnox (Zolpidem), will be sold in packs of no greater than 14 tablets - down from 21, from now on.

The updated warning comes as a result of numerous reports of strange and potentially dangerous side-effects which include changes in behaviour and mental state, sleep walking, and undertaking strange and potentially dangerous behaviours while apparently asleep.

Studies say that Stilnox packs will include significantly changed Consumer Medicine Information (CMI) information about the side effects of Zolpidem which now include the less common adverse effects of rage reactions, worsened insomnia, confusion, agitation, hallucinations and other forms of unwanted behaviour.

Sleep walking, driving motor vehicles and other unusual and on some occasions dangerous behaviours while apparently asleep have been reported along with preparing and eating food, making phone calls and having sexual intercourse. People experiencing these effects apparently have had no memory of the events and significantly such side effects can occur at therapeutic doses, without any intake of alcohol. It is also reported that alcohol intake heightens the risk of such side effects, both for first-time and regular users, at prescribed doses and without the consumption of alcohol.

US Food and Drug Administration (FDA) requested that all manufacturers of sedative-hypnotic drug products, such as Stilnox update their product labeling to include stronger language concerning potential risks. These risks listed by the FDA include severe allergic reactions and complex sleep-related behaviours, including sleep-driving.

Also included were warnings about anaphylaxis (severe allergic reaction) and angioedema (severe facial swelling), which can occur as early as the first time the product is taken and complex sleep-related behaviours which may include making phone calls, and preparing and eating food (while asleep).

Experts say patients being treated with sleep medications should read the information before taking the product and talk to their doctors if they have questions or concerns.

The FDA has recommended that the drug manufacturers conduct clinical studies to investigate the frequency with which sleep-driving and other complex behaviours occur in association with individual drug products.

Abdominal Epilepsy?

The other day, I encountered an uncommon medical diagnosis, abdominal epilepsy. Maybe I was absent when this was taught in med school or maybe it was mentioned but it just didn't register in my memory bank. Anyway, for those colleagues who haven't heard of this as well, here's what I found out about it, so that next time you are faced with a weird abdominal pain, you will think of abdominal epilepsy as a differential. There are many medical causes of abdominal pain; abdominal epilepsy is one of the rare causes. From a medical perspective, the term epilepsy refers not to a single disease, but to a group of symptoms with numerous causes. The common factor in all forms of epilepsy is an excessive electrical excitability of the brain. The increased excitation is called a seizure and may manifest as a partial or total loss of consciousness and muscle spasms or other involuntary movements. Many conditions can produce epilepsy. For example, a genetic predisposition is...

"Ganacity"

If there's one word that I will never forget from my AGSB experience, it's "ganacity"! A word frequently mentioned by our FinMan professor. What does it mean? It's a combination of the tagalog word "gana" (appetite, zest) and the english suffix "city" which converts an adjective word into a noun. 'Ganacity' therefore refers to one's state of desire or interest in something. I am sharing this because I feel that my 'ganacity' for what I am doing now is spiralling down, and it is so difficult to reverse it back up or just to keep it at a maintained level. It is becoming a struggle on a day to day basis. I am hoping that night and day will alternate fast so that this battle will end soon.

Growths and Tumors of the Mouth

A colleague in the practice of dental medicine referred to me a 40-year old female with a large pinkish, cauliflower-like mass on her lower right buccal gingival. It apparently started 2 months prior to the consult as a small pinkish pedunculated mass, nontender, that was often irritated during teeth brushing. She wanted it removed. Without biopsy, the characteristic of the mass is more consistent with squamous papilloma. I scheduled her for excision biopsy under local anesthesia. More and more people are experiencing some ‘growths’ in their oral cavity. I think this is mainly related to the lifestyle we have adapted these years. Smoking, eating food with irritants or preservatives etc. are the usual culprits. For information, these are the more common growths and tumors that we usually see in the oral cavity. Please be guided and consult your dentists if you notice something similar in your mouth. Abscess This is a soft, pus containing swelling. Th...
