Citra 100 mg 100 mg contains tramadol hydrochloride, a centrally-acting analgesic used for the short-term management of moderate to moderately-severe pain. Manufactured by Collins Pharmaceuticals to WHO-GMP standards, Citra 100 mg delivers the same 100 mg dose as brand-name Ultram®, at a fraction of the price.
Unlike traditional strong opioids, tramadol works through a dual mechanism: it binds weakly to opioid receptors while also inhibiting the reuptake of serotonin and noradrenaline in the spinal cord. This gives tramadol a distinct analgesic profile — often described as gentler on breathing than pure opioids, though it still carries controlled-substance risk.

How Citra 100 mg 100 mg works
Tramadol acts on two systems at once. It binds to mu-opioid receptors in the brain and spinal cord — the same receptors that respond to morphine, but with much weaker affinity. It also blocks the reuptake of serotonin and noradrenaline, boosting the natural pain-dampening pathways that descend from the brain into the spinal cord. Together these actions reduce the perceived intensity of pain signals.
Who Citra 100 mg 100 mg is for
Citra 100 mg is generally prescribed for adults dealing with:
- Moderate to moderately-severe acute pain (post-surgical, dental, injury)
- Chronic musculoskeletal pain where non-opioid options are insufficient
- Painful conditions requiring around-the-clock analgesia for a short period
Tramadol is intended for short-term use and always at the lowest effective dose. Longer-term use requires close medical supervision because tolerance and dependence can develop.
How to take Citra 100 mg 100 mg safely
- Follow your prescriber exactly. Do not exceed the daily dose — most adults should not exceed 400 mg in 24 hours.
- Swallow whole with water. Do not cut, crush or chew — this can cause a dangerous “dose-dumping” of tramadol.
- Space doses evenly. Typical spacing is every 4–6 hours; never take a second dose within 4 hours.
- Take with or without food. Food does not significantly change absorption.
- Do not stop abruptly after prolonged use — taper under medical guidance.
Common side effects
- Nausea, vomiting or constipation
- Dizziness and light-headedness
- Headache and drowsiness
- Dry mouth
- Sweating
Serious effects that require immediate care
- Slow, shallow or noisy breathing
- Severe drowsiness that leads to non-response
- Seizures (risk is higher with high doses or in patients on antidepressants)
- Serotonin syndrome (agitation, rapid heart rate, high temperature, muscle rigidity)
- Severe allergic reaction (swelling, difficulty breathing)
Warnings and precautions
Tell your prescriber before starting Citra 100 mg if you have a history of substance-use disorder, seizures, head injury, breathing problems (asthma, COPD, sleep apnoea), liver or kidney disease, or depression. Older adults and anyone weighing under 110 lb may need a lower starting dose.
Do not combine tramadol with
- Alcohol — dangerously increases sedation and respiratory depression
- Other opioids or benzodiazepines — compounding CNS depression, risk of overdose
- MAO inhibitors and many SSRIs / SNRIs — risk of serotonin syndrome
- Certain seizure medications and other serotonergic drugs
Pregnancy, breastfeeding and fertility
Tramadol crosses the placenta and passes into breast milk. Neonates exposed near birth can develop withdrawal symptoms. If you are pregnant, planning pregnancy or nursing, discuss safer analgesic alternatives with your healthcare provider.
