Sinequan (active ingredient: doxepin hydrochloride) is a prescription medication indicated for the following:

Depression: Sinequan is used for the treatment of depressive disorders, including major depressive disorder.
Anxiety Disorders: It is also indicated for the treatment of anxiety disorders and for the management of anxiety associated with depression.

Sinequan belongs to a class of drugs known as tricyclic antidepressants (TCAs), which work by inhibiting the reuptake of neurotransmitters such as norepinephrine and serotonin, thereby helping to elevate mood and reduce anxiety.

Sinequan is available in capsule form, and the dosage and administration instructions are based on the patient’s medical condition and response to treatment, as determined by their doctor. Generally, Sinequan is taken orally, usually 1 to 3 times daily or as directed by the doctor. If the patient takes it only once a day, it should be taken at bedtime to reduce daytime sleepiness. The medication should be taken regularly to get the most benefit from it, and the dosage should not be increased, or the drug used more often or for longer than prescribed.

To reduce the risk of side effects such as drowsiness, dry mouth, and dizziness, the doctor may direct the patient to start at a low dose and gradually increase it. The medication should be taken with water or milk and should not be mixed with soda or other carbonated beverages. If the patient is taking the medication in combination with liquid methadone, it may be mixed with lemonade, orange juice, sugar water, or plain water, but not grape juice.

Continue taking Sinequan even if the patient feels well, and to not stop taking the medication without consulting their doctor first. Suddenly stopping the medication may worsen certain conditions or cause withdrawal symptoms like mood swings, headaches, and tiredness. The doctor may gradually reduce the patient’s dose to prevent these symptoms while stopping treatment.

It may take up to 3 weeks for the full effect of Sinequan to be felt, and any new or worsening symptoms should be reported to the doctor right away. As with all medications, follow the doctor’s instructions carefully and report any concerns or side effects.

Sinequan can cause anticholinergic side effects, such as dry mouth, constipation, blurred vision, urinary retention, and confusion, especially in elderly or sensitive patients.
Patients with a history of cardiovascular disease or recent myocardial infarction should be cautious when taking Sinequan due to its potential to cause arrhythmias or heart block.
Patients with a history of liver or kidney disease should use Sinequan with caution and at lower dosages because the medication may accumulate in their bodies, leading to toxicity.
Sinequan can interact with other medications or substances, such as central nervous system depressants, anticholinergics, or monoamine oxidase inhibitors (MAOIs), and cause adverse effects or reduced efficacy. Patients should inform their doctor before starting or stopping any medications or supplements.
Sinequan may cause withdrawal symptoms if the medication is suddenly stopped, or the dosage is reduced too quickly. Symptoms may include nausea, headache, dizziness, insomnia, or fatigue. Patients should taper off Sinequan gradually under medical supervision.
