Is this effective as a sleep aid? Is it better than taking low dosage first generation antihistamines as a sleep aid?  Is it available in Thailand? 

Trazodone is available in Thailand but I think not in 25mg does. 50 mg and I'm not sure if the tablets are scored or not.

 

Its use for insomnia is off-label.  

 

While drowsiness is the most common side effecst there are other m0ore serious ones in some peopel inlcuding heart abnormalities. Best to get a doctor's advice first before taking.

 

Antihistamines like doxylamine (Sominar) and hydroxyzine (many brands) are more readily available. These too can cause grogginess and may affect cognition especially in the elderly and especially if taken every night.
