The 100mg tablet is a frequently prescribed dose, either as a standalone daily dose or to be taken more than once per day.
Can You Cut a 100mg Trazodone Tablet in Half?
Is It Safe to Split Trazodone?
Yes, in many cases, 100mg trazodone tablets can be safely split in half—but it depends on the type of tablet you have. If your tablet is scored (has a line down the middle), it is generally designed to be split.
Important: Always consult your doctor or pharmacist before splitting any medication.
Why People Split Trazodone
There are several reasons why someone might want to split a 100mg trazodone tablet:
- Lower the dosage (e.g., taking 50mg instead of 100mg)
- Titrate the dose gradually when starting or stopping the medication
- Save money by purchasing higher-dose tablets and splitting them
- Reduce side effects by taking a smaller amount
How to Split Trazodone Safely
If your doctor approves splitting your trazodone tablet, follow these guidelines:
Use a Pill Cutter
- A pill cutter is the safest and most accurate way to split tablets.
- Avoid using knives or breaking the pill by hand, as this can result in uneven dosages.
Store Properly
- Keep the unused half in a clean, dry container.
- Make sure it’s clearly labeled to avoid confusion.
Only Split Immediate-Release Tablets
- Do not split extended-release (XR or ER) tablets.
- Splitting these can alter the way the medication is absorbed, leading to unwanted side effects or reduced effectiveness.
What Happens If You Take Half a 100mg Trazodone?
Half-Life and Duration
When you take 50mg of trazodone (half of a 100mg tablet), the medication still follows the same half-life of about 5 to 13 hours, meaning it stays in your system for a reasonable amount of time to be effective.
Effects at Lower Doses
Lower doses of trazodone (25–50mg) are commonly used to:
- Treat insomnia
- Reduce anxiety
- Provide milder antidepressant effects
So taking half a 100mg tablet may still be effective, depending on your condition and treatment goals.
Potential Side Effects of Trazodone (Even in Half Doses)
Whether you take a full or half dose of trazodone, you may still experience side effects. Common ones include:
- Drowsiness
- Dizziness or lightheadedness
- Dry mouth
- Nausea
- Headache
When to Contact Your Doctor
Seek medical attention if you experience:
- Irregular heartbeat
- Severe drowsiness
- Difficulty breathing
- Suicidal thoughts or behavior
Tips for Taking Trazodone Safely
- Always take trazodone as prescribed by your healthcare provider.
- Take it with food to reduce stomach upset.
- Avoid alcohol, as it can intensify drowsiness and other side effects.
- Don’t suddenly stop taking trazodone—talk to your doctor about tapering your dose.
