Amitriptyline FAQs
Generally, amitriptyline is taken at bedtime due to its sedative effect, which can help improve sleep quality.
However, some people may prefer to take it earlier in the evening to minimize daytime drowsiness or before engaging in activities that require alertness, such as driving or operating machinery.
Amitriptyline can begin to take effect after one to two weeks, but its full effects may not be noticeable for up to six weeks.
Yes, weight gain is a common side effect reported by some people taking amitriptyline. One study found that people taking amitriptyline gained between 1 lb and 16 lbs.
Health experts are still not sure what the exact cause of this is, but some speculate that appetite improves once depression symptoms lessen.
Amitriptyline is not classified as a controlled substance in the United States, but it does require a prescription.
However, even though it is not a controlled substance, amitriptyline should be used with caution and only under the supervision of a healthcare provider due to its potential for side effects and interactions with other medications.
Amitriptyline can interact with various medications, affecting its effectiveness or increasing the risk of side effects.
Some medications that may interact with amitriptyline include:
- Other antidepressants, such as SSRIs, SNRIs, MAOIs, or other TCAs
- Anticholinergic medications, including some antihistamines, antispasmodics, and medications for overactive bladder
- Certain antihypertensive drugs
- Drugs that affect liver enzymes, such as certain antifungal medications, antibiotics, or antivirals
- Central nervous system depressants, such as alcohol, sedatives, or opioids
Additionally, combining amitriptyline with certain medications may increase the risk of serotonin syndrome, a potentially life-threatening condition characterized by high levels of serotonin in the brain.
Symptoms of serotonin syndrome may include agitation, hallucinations, rapid heartbeat, fever, excessive sweating, shivering, tremors, muscle twitching, and gastrointestinal issues.
The most common side effects of amitriptyline include:
- Dry mouth
- Blurred vision
- Constipation
- Urinary retention
- Dizziness or lightheadedness
- Drowsiness or fatigue
- Weight gain
- Increased heart rate
- Tremors
- Sweating
Less common but more serious side effects may include:
- Confusion or hallucinations
- Irregular heartbeat
- Difficulty urinating
- Seizures
- Allergic reactions (rash, itching, swelling)
If you experience any severe or persistent side effects while taking amitriptyline, it's essential to contact your healthcare provider immediately. They can evaluate your symptoms and determine if any changes to your treatment plan are necessary.
Additionally, abrupt discontinuation of amitriptyline should be avoided, as it may lead to withdrawal symptoms. Always consult with your healthcare provider before making any changes to your medication regimen.
