Key takeaways
Tramadol is an opioid painkiller that acts on the same receptors as morphine-type drugs, with real dependence potential.
In Thailand it has been under special Thai FDA controls since 2015 after widespread misuse: pharmacies face sale limits, record-keeping and a ban on selling to minors.
Menscape prescribes it only for short, defined courses, such as after surgery, and only after a doctor screens for seizure history, antidepressant use and dependence risk.
Seizures and serotonin syndrome are documented risks, and mixing tramadol with alcohol, sedatives or antidepressants can be dangerous.
01
What tramadol is & why it's restricted
Tramadol is a prescription opioid painkiller used for moderate-to-severe pain, including pain after surgery. It spent decades marketed as a milder, safer opioid. The evidence since then says otherwise: tramadol carries genuine risks of dependence, seizures and drug interactions, which is why regulators from Bangkok to Washington have tightened controls on it.²
It works in two ways at once. Part of its effect comes from conversion in the liver into an opioid metabolite that binds the same mu-receptors morphine does. The rest comes from boosting serotonin and noradrenaline signalling, similar to some antidepressants. This dual action relieves pain, but it also creates tramadol's specific dangers: opioid-type dependence and slowed breathing on one side, seizures and serotonin syndrome on the other.⁶
How strongly it works also varies from person to person. The liver enzyme that activates tramadol (CYP2D6) differs genetically: some men get a much stronger opioid effect than expected, others almost none.¹ That unpredictability is one more reason it belongs under a doctor's supervision, not on a shelf.
A prodrug, activated in the liver
The liver converts tramadol into an opioid metabolite (O-desmethyltramadol) that binds mu-opioid receptors, the same target as morphine-type drugs.¹
A second, antidepressant-like action
The parent drug also blocks serotonin and noradrenaline reuptake, dampening pain signals in the spinal cord.⁶
Pain relief, with two risk profiles
Together the two actions relieve moderate-to-severe pain, and each brings its own risks: dependence from one, seizures and serotonin syndrome from the other.²
Effect varies by genetics
CYP2D6 enzyme differences mean some men feel a far stronger opioid effect than others from the same tablet, and some feel almost nothing.¹

Getting tramadol in Thailand
Thai legal status
Tramadol is a prescription-class medicine under special Thai FDA control measures introduced in 2015 after widespread misuse: pharmacies must keep sales records, quantities are capped and sale to minors is banned.³ It is sold in Thailand under brands such as Tramal and as registered generics.
How Menscape dispenses it
Only against a doctor's prescription, and only for short, defined courses such as post-operative pain. The doctor screens for seizure history, antidepressant use and dependence risk first, and no course is repeated without a review.
Grey market & travel risk
Street and online tramadol is illegal in Thailand and frequently counterfeit or adulterated. Travellers should know that several countries treat tramadol as a strictly controlled narcotic; carrying loose tablets across borders can mean arrest. Keep it in original packaging with the prescription.
Thai FDA control measures, 2015: mandatory sales records, per-purchase quantity limits and prohibition of sale to minors, introduced after documented misuse of tramadol cocktails among Thai teenagers.³ Menscape dispenses tramadol by doctor's prescription only.
03
Does it work? The evidence
For moderate acute pain, tramadol works, but less impressively than its reputation suggests. In a pooled analysis of 3,453 post-operative patients, a standard single dose gave one additional patient meaningful (50%) pain relief for roughly every five treated, compared with placebo.⁴
The honest comparison is uncomfortable: in the same body of single-dose trials, a plain over-the-counter anti-inflammatory achieves that relief for roughly every 2–3 patients treated.⁷ For most pain, a non-opioid works as well or better. Tramadol's legitimate place is narrow: short courses when anti-inflammatories are unsuitable or insufficient, under medical supervision. For chronic pain, evidence of long-term benefit is weak, while dependence risk grows with every week of use.²

04
Side effects & who shouldn't take it
Common side effects
Nausea and dizziness each affect roughly 1 in 4 people at label doses; vomiting, constipation, drowsiness, sweating and headache are also common.¹ Do not drive or operate machinery until you know how it affects you.
Serious risks
Seizures can occur even at prescribed doses, and the risk rises sharply with higher doses or interacting drugs.⁶ Serotonin syndrome, dangerously slowed breathing (especially with alcohol or sedatives) and dependence with withdrawal on stopping are all documented.¹ ²
Not suitable for
Men with epilepsy or a history of seizures, anyone taking MAOIs, men with a history of substance misuse or dependence, severe breathing problems, or significant liver or kidney disease. Antidepressant users need a specific medical review before any prescription.
Interactions that matter
SSRIs and SNRIs raise both seizure and serotonin-syndrome risk. Alcohol, benzodiazepines and sleeping tablets add dangerous sedation and breathing suppression. Carbamazepine cuts tramadol's effect. Tell the doctor everything you take, including supplements.
05
Alternatives & combinations
Non-opioid · first-line
Paracetamol + NSAIDs
For most moderate pain, paracetamol combined with an anti-inflammatory such as ibuprofen or etoricoxib relieves pain as well as tramadol in trials, without opioid risks.⁷ This is where a Menscape doctor starts.
Prescription · nerve pain
Gabapentin
Burning or shooting nerve pain responds poorly to opioids. Gabapentin targets neuropathic pain directly and is the usual prescription route for it, with its own risks a doctor will explain.
Post-surgery
Structured aftercare
After procedures at Menscape, pain control is planned in advance: anti-inflammatories and local measures first, with tramadol held in reserve for short-term use only if the doctor judges it necessary.

Message us on WhatsApp or LINE
Five minutes on your phone: where the pain is, how long you have had it, what you already take. PDPA-protected, and reviewed before any consultation.
Doctor consultation
A licensed Thai physician assesses the cause of the pain first, then screens for seizure history, antidepressants, alcohol use and dependence risk. For a controlled medicine, an in-clinic visit at Asoke may be required.
Prescription, if suitable
If the doctor decides tramadol is appropriate, you receive a short course with a defined stop date, dispensed by a licensed pharmacy. No repeats without a new review.
Follow-up & stop plan
A check-in at the end of the course. Pain that persists means re-assessing the cause, not simply more tablets.
The doctor decides. Starting a conversation is not a commitment and does not guarantee a prescription. Tramadol is prescribed only when a doctor judges it necessary, for the shortest course that does the job. If it is not right for you, your doctor will say so and discuss alternatives.

Frequently asked questions
Can I buy tramadol over the counter in Thailand?
No. Since 2015 tramadol has been under special Thai FDA controls: pharmacies must record every sale, quantities are capped and sale to minors is banned. At Menscape it is dispensed only against a doctor's prescription. Anything sold loose, online or without questions is illegal and a counterfeit risk.
Is tramadol an opioid?
Yes. Part of its effect comes from an opioid metabolite acting on the same receptors as morphine, alongside a second antidepressant-like mechanism. It was long marketed as a milder option, but regulators now treat it as an opioid with real dependence potential.
Why did Thailand restrict tramadol?
Documented misuse, particularly teenagers mixing tramadol with cough syrup and soft drinks in the early 2010s. The Thai FDA responded in 2015 with mandatory sales records, quantity caps and a ban on sale to minors.
Will a Menscape doctor prescribe tramadol for chronic pain?
Usually not. Evidence for long-term benefit is weak and dependence risk grows with duration of use. If pain has lasted weeks, the priority is diagnosing the cause; the doctor will discuss non-opioid options and refer you if needed.
Can I take tramadol with my antidepressant?
Not without a doctor's review. Combining tramadol with SSRIs, SNRIs or MAOIs raises the risk of serotonin syndrome and lowers the seizure threshold. Tell the doctor exactly what you take; this combination is a common reason a tramadol prescription is refused.
Can I drink alcohol while taking tramadol?
No. Alcohol adds to tramadol's sedative effect and can dangerously suppress breathing. Skip alcohol entirely for the full course.
Can I travel with tramadol prescribed in Thailand?
With care. Several countries classify tramadol as a strictly controlled narcotic, and carrying loose tablets across a border can lead to arrest. Keep it in the original packaging with your prescription, and check the destination country's rules before you fly.
What happens if I stop tramadol after taking it regularly?
Withdrawal is possible after regular use: agitation, anxiety, sweating, insomnia and flu-like symptoms, sometimes with unusual features linked to its serotonin action. If you have been taking it for more than a couple of weeks, ask a doctor about tapering rather than stopping abruptly.
