Can I take Ashwagandha and Sertraline together?

Guide för läkemedelsinteraktioner

Taking ashwagandha with sertraline may increase the risk of side effects such as extreme drowsiness, dizziness, and confusion.

There is also a theoretical risk of a rare but serious condition called serotonin syndrome, which can cause shivering, sweating, and a fast heartbeat.

Additionally, ashwagandha may interfere with how your liver processes sertraline, potentially leading to higher levels of the medication in your body.

Varför detta händer

Both substances can have a calming effect on the central nervous system, which can lead to excessive sedation when combined.

Ashwagandha may also slightly increase serotonin levels, adding to the effects of sertraline and slow down the liver enzymes (specifically CYP450 enzymes) that break down sertraline, causing the drug to stay in your system longer.

  • You should consult your doctor or pharmacist before combining these two.

  • If you decide to take them together, start with a low dose of ashwagandha and monitor yourself closely for excessive sleepiness or mood changes.

  • Seek medical help immediately if you experience high fever, agitation, or muscle stiffness.

Depression and anxiety disorders

You may experience an increase in suicidal thoughts or the urge to self-harm when first starting sertraline or changing the dose. This is more common in young adults under 25. Contact your doctor or go to hospital immediately if you notice any changes in your mood or behaviour.

Serotonin Syndrome

Both substances can increase serotonin levels. Taking them together significantly raises the risk of serotonin syndrome, a potentially life-threatening condition.

Seek immediate medical help if you experience agitation, rapid heartbeat, or muscle twitching.

Hyperthyroidism (overactive thyroid)

Ashwagandha can increase thyroid hormone levels. It must be avoided if you have an overactive thyroid or are taking thyroid medication, as it can worsen the condition or interfere with your treatment.

Autoimmune Diseases

Ashwagandha can stimulate the immune system, which may cause autoimmune diseases such as lupus, rheumatoid arthritis, and MS to become more active. It should be avoided if you have any of these conditions.

Bleeding disorders

Sertraline can increase your risk of bleeding, particularly in the stomach or skin. Use with caution if you take blood-thinning medications (like warfarin) or anti-inflammatory painkillers (like ibuprofen or aspirin).

Alkohol

You should avoid drinking alcohol while taking sertraline. Alcohol can increase the sedative effects of the medication, making you feel more drowsy, dizzy, or uncoordinated. It can also worsen the symptoms of depression or anxiety that the medicine is treating.

It is best to avoid or strictly limit alcohol when taking ashwagandha. Ashwagandha has sedative properties, and combining it with alcohol can cause excessive drowsiness, impaired coordination, and slowed breathing.

Grapefruit juice

Grapefruit juice can increase the levels of sertraline in your blood by slowing down how your body breaks it down. This may increase the risk of side effects.

While the effect is less severe than with some other antidepressants, it is best to avoid large amounts of grapefruit juice.

Caffeine

Sertraline can sometimes cause jitteriness or tremors. High intake of caffeine (found in coffee, tea, and energy drinks) can worsen these side effects and may increase feelings of anxiety.
