What is Sinequan?

Sinequan is an orally administered medication classified as a tricyclic antidepressant (TCA). Its active ingredient is Doxepin. The available forms are pills in strengths of 10mg, 25mg, and 75mg. Doxepin was developed and first marketed in the 1960s. Generic versions of Doxepin are widely available, offering a more cost-effective option. While the original brand name was Sinequan, other brand names containing Doxepin may also be encountered. Generic alternatives containing Doxepin may be available at lower cost.

How Doxepin Works

The precise mechanism of action for Sinequan (Doxepin) isn't fully understood, but it is believed to work by increasing the levels of certain neurotransmitters, primarily norepinephrine and serotonin, in the brain. These neurotransmitters are thought to be involved in regulating mood. By inhibiting their reuptake (the process by which they are reabsorbed into nerve cells), Sinequan effectively makes more of these chemicals available in the synaptic space, which can help to alleviate symptoms of depression and anxiety. Doxepin also has anticholinergic, antihistaminic, and antiadrenergic effects, which contribute to its overall therapeutic profile and some of its side effects. The onset of therapeutic effects can take several weeks.

Conditions Treated with Sinequan

Sinequan (Doxepin) is approved for the treatment of the following conditions:

• Depression: It is effective in managing various forms of depression, including major depressive disorder. By increasing the availability of key neurotransmitters like serotonin and norepinephrine, Sinequan helps to improve mood, increase energy levels, and reduce feelings of sadness and hopelessness.
• Anxiety: The medication is also used to treat anxiety associated with depression. Its effects on neurotransmitters can calm the nervous system, reducing feelings of worry, tension, and panic.
• Itching (Pruritus): In lower doses, Sinequan is often prescribed to alleviate severe itching, particularly when it interferes with sleep. Its antihistaminic properties are believed to contribute to this effect, providing relief from chronic discomfort.

Is Sinequan the Right Medication for You?

Sinequan (Doxepin) is a suitable option for adults diagnosed with depression or anxiety disorders who have not responded adequately to other treatments, or for those experiencing severe itching that disrupts sleep. Its broad spectrum of action makes it a versatile choice for managing mood disorders. However, it may not be appropriate for individuals with certain pre-existing medical conditions, such as uncontrolled glaucoma, urinary retention, or a recent history of heart attack. It is also not recommended for individuals who are pregnant or breastfeeding without careful consideration of risks and benefits, or those taking monoamine oxidase inhibitors (MAOIs) or certain other medications, due to the risk of serious interactions.

Use: Dosing, Missed Dose, Overdose

Dosing Information

The dosage of Sinequan (Doxepin) is highly individualized and depends on the condition being treated and the patient's response.

• For Depression and Anxiety: Typical starting doses for adults range from 25mg to 75mg per day, divided into multiple doses, with a larger portion taken at bedtime if sedation is desired. Doses can be gradually increased to a maximum of 300mg per day under medical supervision.
• For Itching: Lower doses, often starting at 3mg to 6mg, are typically prescribed at bedtime to help with sleep and reduce nighttime itching.

Missed Dose

If you miss a dose of Sinequan, take it as soon as you remember, unless it is almost time for your next scheduled dose. If it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one.

If an overdose is suspected, seek immediate medical attention by calling emergency services or a poison control centre.

• Alcohol: Avoid consuming alcohol while taking Sinequan, as it can intensify drowsiness and increase the risk of side effects.
• Operating Machinery: Sinequan can cause drowsiness, dizziness, and blurred vision. Avoid driving or operating heavy machinery until you know how this medication affects you.
• Administration: Sinequan pills can be taken with or without food. If taken for itching, it is often best administered before bedtime.

Safety Information

⚠️ Who Should Not Take Sinequan

Sinequan (Doxepin) is contraindicated in individuals with a known hypersensitivity to Doxepin or other tricyclic antidepressants. It should not be used in patients who are currently taking or have recently taken monoamine oxidase inhibitors (MAOIs), as this can lead to a severe and potentially fatal interaction. Caution is advised in patients with:

• Glaucoma (particularly narrow-angle glaucoma)
• Urinary retention or prostatic hypertrophy
• Seizure disorders
• Hyperthyroidism or cardiovascular disease
• Liver impairment

Common Side Effects

Many people taking Sinequan experience mild side effects that tend to diminish as the body adjusts to the medication. Common side effects include:

• Drowsiness and sedation
• Dry mouth
• Constipation
• Blurred vision
• Dizziness
• Weight gain
• Increased sweating

These effects can often be managed by adjusting the dosage or timing of administration.

Serious Side Effects (Seek Immediate Medical Help)

Although rare, serious side effects can occur. Seek immediate medical attention if you experience any of the following:

• Suicidal thoughts or behaviour changes
• Serotonin syndrome (symptoms include agitation, hallucinations, rapid heart rate, fever, muscle stiffness, confusion)
• Severe allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing)
• Irregular heart rhythm (palpitations, chest pain)
• Seizures
• Unusual bleeding or bruising

Drug & Food Interactions

Sinequan (Doxepin) can interact with various medications and substances, potentially altering its effectiveness or increasing the risk of side effects:

• Monoamine Oxidase Inhibitors (MAOIs): A dangerous interaction can occur, leading to fever, seizures, and even death. Do not take MAOIs within 14 days of stopping Sinequan, and vice versa.
• Central Nervous System (CNS) Depressants: Alcohol, sedatives, sleeping pills, and other antidepressants can increase drowsiness when taken with Sinequan.
• Anticholinergic Drugs: Concurrent use can potentiate anticholinergic effects like dry mouth, blurred vision, constipation, and urinary retention.
• Thyroid Hormones: Concurrent use may increase the risk of cardiac arrhythmias.
• Certain Blood Pressure Medications: Effects of some antihypertensives may be reduced.
• Grapefruit Juice: May inhibit the metabolism of Doxepin, leading to increased side effects.

Off-Label and Investigational Uses of Sinequan

In addition to its approved indications, Sinequan (Doxepin) has been used off-label for several other conditions based on clinical observations and some research findings. It is important to note that these uses are not officially approved by regulatory bodies, and efficacy and safety in these contexts may not be as well-established.

• Histamine Intolerance: Due to its potent antihistaminic properties, low-dose Doxepin is sometimes used to manage symptoms of histamine intolerance, such as chronic hives, headaches, and digestive issues, especially when other treatments are ineffective.
• Insomnia: In lower doses, Sinequan is frequently prescribed as a hypnotic to treat persistent insomnia, particularly when traditional sleep aids are not suitable or have proven ineffective. Its sedative effect can help individuals fall asleep and stay asleep.
• Pain Management: Some studies and clinical practices have explored the use of Doxepin for chronic pain conditions, such as neuropathic pain, as TCAs can modulate pain pathways.

Any off-label use of Sinequan should only be undertaken under the direct supervision of a qualified healthcare provider who can carefully monitor for efficacy and potential adverse effects.

Storage & Handling

Sinequan (Doxepin) pills should be stored at room temperature, typically between 20°C to 25°C (68°F to 77°F). It is important to keep the medication in its original container to protect it from light and moisture. Avoid storing it in bathrooms or other damp environments. Do not use the medication if the expiry date has passed. If you have expired Sinequan, it is recommended to dispose of it safely according to local guidelines for pharmaceutical waste, often by returning it to a local pharmacy for proper disposal.
