Doxavit

Doxavit is indicated for the treatment of nausea and vomiting of pregnancy in women who do not respond to conservative management.

Doxylamine Succinate is an antihistamine that blocks Histamine (H1) receptor. It can cross the blood brain barrier and has a high affinity for H1 receptors in the brain that blocks H1 receptors. It also decreases the action of histamine at the H1 receptor by inhibiting both vestibular system & Muscarinic receptor. It affects the vestibular system & decreases the stimulation of the vomiting center. Its muscarinic receptor inhibition may also play a role in antihistamine antiemetic activity. Pyridoxine Hydrochloride is a vitamin B6 analog. It is used to prevent nausea and vomiting due to its antiemetic properties.

Initially, take one tablet orally at bedtime (Day 1). If this dose adequately controls symptoms the next day, continue taking one tablet daily at bedtime only. However, if symptoms persist on Day 2, increase the daily dose to one tablet in the morning and one tablet at bedtime. The maximum recommended dose is two tablets per day, one in the morning and one at bedtime. Take on an empty stomach with a glass of water. Swallow tablets whole. Do not crush, chew, or split this tablets. Take daily and not on an as needed basis.

Use of Doxylamine Succinate & Pyridoxine Hydrochloride is contraindicated in women who are taking monoamine oxidase inhibitors (MAOIs), which prolong and intensify the adverse central nervous system effects (the anticholinergic effects) of antihistamines. Concurrent use of alcohol and other CNS depressants (such as hypnotic sedatives and tranquilizers) with Doxylamine Succinate & Pyridoxine Hydrochloride is not recommended.

Doxylamine Succinate & Pyridoxine Hydrochloride is contraindicated in women with any of the following conditions:

Known hypersensitivity to Doxylamine Succinate, other ethanolamine derivative antihistamines, Pyridoxine Hydrochloride or any inactive ingredient in the formulation

Monoamine oxidase (MAO) inhibitors intensify and prolong the adverse central nervous system effects of Doxylamine Succinate & Pyridoxine Hydrochloride

Somnolence or other accidents resulting from the effect of the combined use of Doxylamine Succinate & Pyridoxine Hydrochloride with CNS depressants.

Doxylamine Succinate & Pyridoxine Hydrochloride use is not recommended if a woman is concurrently using central nervous system (CNS) depressants including alcohol.
