Tramadol

Brand names: Ultram, ConZip

Atypical Opioid AnalgesicsSchedule IV

Key Takeaway

Tramadol is a centrally acting opioid analgesic used for moderate to moderately severe pain in adults. It is classified as DEA Schedule IV due to lower (but real) abuse potential compared to stronger opioids. [1]

Controlled Substance — DEA Schedule IV

Tramadol is a federally controlled substance. It has potential for abuse and dependence. Your prescriber will monitor you while taking this medication.

If you or someone you know is struggling with substance use, call the SAMHSA National Helpline: 1-800-662-4357 (free, confidential, 24/7).

How does Tramadol work?

Tramadol works through two mechanisms: it binds to mu-opioid receptors in the brain and spinal cord to reduce pain perception, and it inhibits the reuptake of norepinephrine and serotonin, which contributes additional pain-relieving effects. [1] This dual mechanism distinguishes tramadol from traditional opioids and contributes to its somewhat lower abuse liability.

What to expect when starting Tramadol

Most patients notice pain relief within 1 hour of taking immediate-release tramadol. [1] Common early side effects include nausea, dizziness, and drowsiness, which often diminish after the first week. Take with or without food. Do not crush, break, or chew extended-release tablets.

What are the common side effects of Tramadol?

Common

Common(8 effects)
  • Nausea (24%)
  • Dizziness (26%)
  • Constipation (24%)
  • Headache (18%)
  • Drowsiness (16%)
  • Vomiting (9%)
  • Dry mouth (6%)
  • Fatigue (6%)

What are the serious side effects of Tramadol?

Serious

Common(6 effects)
  • Seizures — risk increases with higher doses, especially above 400 mg/day [1]
  • Serotonin syndrome — when combined with SSRIs, SNRIs, triptans, or MAO inhibitors [1]
  • Respiratory depression — risk increases with CNS depressants, particularly benzodiazepines [1]
  • Anaphylactic reactions — rare but reported; discontinue immediately if suspected [1]
  • Adrenal insufficiency — with prolonged use; presents as fatigue, weakness, nausea [1]
  • Neonatal opioid withdrawal syndrome — if used during pregnancy [1]

What drugs interact with Tramadol?

  • Major
    SSRIs (sertraline, fluoxetine, citalopram) — Risk of serotonin syndrome — potentially life-threatening. Symptoms include agitation, hallucinations, rapid heartbeat, fever, muscle rigidity, and coordination loss. [1]
  • Major
    Benzodiazepines (diazepam, alprazolam, clonazepam) — Combined use increases risk of profound sedation, respiratory depression, coma, and death. Use together only when alternatives are inadequate. [1]
  • Contraindicated
    MAO inhibitors (selegiline, phenelzine) — Contraindicated. May potentiate seizure risk and serotonin syndrome. Do not use tramadol within 14 days of MAO inhibitor therapy. [1]
  • Major
    Carbamazepine — Carbamazepine is a CYP3A4 inducer that significantly reduces tramadol concentrations, decreasing analgesic effect. Also lowers the seizure threshold. [1]
  • Moderate
    CYP2D6 inhibitors (fluoxetine, paroxetine, quinidine) — CYP2D6 inhibitors reduce conversion of tramadol to its active metabolite M1, potentially reducing analgesic efficacy. [1]

Can I eat certain foods or drink alcohol with Tramadol?

Avoid alcohol — increases risk of respiratory depression and sedation. [1] Take tramadol with or without food. Avoid grapefruit juice, which may alter drug metabolism.

What is the typical dosage for Tramadol?

Immediate-release tablets: Start at 25 mg once daily in the morning, increase by 25 mg every 3 days to 25 mg four times daily, then increase by 50 mg every 3 days to 50-100 mg every 4-6 hours as needed. Maximum: 400 mg/day. [1]

Extended-release (Ultram ER, ConZip): Start at 100 mg once daily. Increase by 100 mg every 5 days. Maximum: 300 mg/day. [1]

Renal impairment (CrCl < 30 mL/min): Increase dosing interval to every 12 hours. Maximum 200 mg/day. [1]

Hepatic impairment (cirrhosis): 50 mg every 12 hours. Extended-release not recommended. [1]

How much does Tramadol cost?

Tramadol is available as a generic at significantly lower cost than brand-name Ultram or ConZip. A 30-day supply of generic tramadol 50 mg typically costs $4-$15 at most pharmacies. Pharmacy discount programs may further reduce out-of-pocket costs.

Is Tramadol safe during pregnancy or breastfeeding?

Pregnancy Category C — animal studies showed adverse effects. Use only if potential benefit justifies risk. Prolonged use during pregnancy can cause neonatal withdrawal syndrome. [1]

Breastfeeding: Tramadol and its active metabolite are excreted in breast milk. Breastfeeding is not recommended during tramadol therapy. [1]

Is there a generic version of Tramadol?

Generic tramadol is bioequivalent to brand-name Ultram. Both contain the same active ingredient and are FDA-approved for the same indications. Generic versions are widely available and substantially less expensive.

For Caregivers

If you are caring for someone taking tramadol, watch for signs of excessive sedation (unusual sleepiness, slow breathing, confusion). Tramadol can lower the seizure threshold — know the signs of a seizure. Do not allow the patient to drink alcohol or take other sedatives unless directed by their doctor. Store securely — tramadol is a controlled substance.
