Buying Sinequan online
Generic Doxepin, much of it made in India, is often available as a more affordable alternative to the original brand.

Patients should ensure they use this medication under the guidance and supervision of their doctor.
Will I receive the original Sinequan?
No. Sinequan is the originator brand name, made by Pfizer, and Yasabai uses it to identify the medicine: you receive a generic with the same active ingredient (doxepin) at the same dose, mostly a recognised Indian branded generic. The exact brand depends on stock.

Doxepin usually starts to work within 2 to 3 weeks. The exact timing differs between people.
