Pain-O-Soma 350mg is a brand-name pharmaceutical product containing Carisoprodol, a prescription-only skeletal muscle relaxant used for the short-term relief of acute, painful musculoskeletal conditions. Approved Uses Muscle Spasms: Fast-acting relief from intense skeletal muscle stiffness, tension, and rigidity. Injury Recovery: Prescribed alongside rest, physical therapy, and lifestyle alterations to recover from acute strains or sprains. Short-Term Therapy: It is strictly indicated for short-term use, generally no longer than 2 to 3 weeks, as long-term efficacy has not been demonstrated and risk of dependency increases
Part of our Pain Relief range.
Pain-O-Soma 350mg is Centurion Laboratories' version of carisoprodol at the classic 350mg strength — the dose around which most prescribing guidance for this muscle relaxant was written. Carisoprodol works centrally, interrupting the pain signalling that keeps a muscle locked in spasm, and is used for short courses in acute musculoskeletal injuries: pulled backs, neck strain, sports injuries, and similar. Pain-O-Soma 350mg attracts two groups of buyers: first-time carisoprodol users following their doctor's advice to start at the standard strength, and returning users who know 350mg works for them and want the widely recognised Pain-O-Soma brand specifically. Because carisoprodol carries dependence potential, it is a medicine for planned short-term use, not a standing item in the bathroom cabinet.
Expect Pain-O-Soma 350mg to begin easing muscle tension within about 30 minutes, with each dose covering roughly four to six hours. That timing shapes how the leaflet structures a treatment day, with doses spaced through waking hours during the acute phase of an injury. The full course is intentionally short — the leaflet caps carisoprodol use at around two to three weeks, matching the natural recovery timeline of most acute muscle strains. If you reach the end of that period and the pain has not settled, that is diagnostic information for your doctor, not a reason to reorder. Take the tablets exactly as the leaflet describes, and resist any temptation to add doses when the effect wears off between them.
Pain-O-Soma 350mg and Prosoma 350 are pharmacologically interchangeable — identical active ingredient, identical 350mg dose, different manufacturers. On Kam4eu, Prosoma 350 is €52 for 20 tablets against €58 for Pain-O-Soma 350mg, so the choice usually comes down to brand preference or prior experience. The step-up options are a different decision entirely. Pain-O-Soma 500mg is not a starting dose and suits only those with confirmed inadequate response to 350mg, while Carisoprodol 1000mg exceeds standard leaflet strengths altogether and belongs exclusively under direct medical supervision. Side effects — sedation, dizziness, dependence — climb with every step up the ladder, so stay at 350mg unless a doctor says otherwise.
Start with the leaflet — it is in the box for a reason, and carisoprodol's interaction list is worth knowing before your first dose. The non-negotiables: no alcohol at any point during the course, since the combination compounds sedation and can suppress breathing; and no driving until you know how drowsy the tablets make you. Tell your doctor about any antidepressants, opioids, or sleep medicines you use. Pain-O-Soma 350mg works best as the pharmacological half of a two-part plan — the tablet manages the spasm while rest, heat, and progressive gentle movement fix the underlying injury. Keep to the leaflet's course length, stop on schedule even if some stiffness remains, and never self-escalate the dose.
When you order Pain-O-Soma 350mg from Kam4eu, you receive the authentic Centurion Laboratories product in factory-sealed blisters — batch number and expiry date visible, GMP-manufactured, patient information leaflet included. Muscle relaxants are a category where counterfeits circulate, so the sealed-and-traceable detail is not marketing filler; it is how you confirm what you are taking. We dispatch in plain packaging to the UK and throughout the EU, with delivery in 3–5 working days and free shipping on orders above €110. A pack of 20 tablets is €58. Before anything ships, we confirm your order over WhatsApp, and that channel stays open for delivery questions. As always: no prescription requirement at checkout does not mean no need for medical advice.
Common side effects of Pain-O-Soma 350mg include drowsiness, dizziness and headache; some users also notice nausea, blurred vision or mild agitation. As the lower of the two Pain-O-Soma strengths, it tends to produce milder sedation than the 500mg tablet — side effects scale with dose — but you should still avoid driving or operating machinery until you know your response. Rare but serious reactions include severe allergic response (swelling, rash, difficulty breathing), seizures, marked confusion, and very slow breathing: seek medical help immediately if any of these appear. Stopping suddenly after extended regular use can trigger withdrawal symptoms. Carisoprodol is a prescription-strength muscle relaxant with dependence potential, meant for short courses of a few weeks at most.
Avoid Pain-O-Soma 350mg if you have any history of drug or alcohol dependence — even at the lower strength, carisoprodol carries genuine dependence potential. It must not be mixed with alcohol, and combining it with other central nervous system depressants such as opioids, benzodiazepines or sleeping tablets risks dangerous levels of sedation and slowed breathing. Do not take it if you have porphyria or a known allergy to carisoprodol or meprobamate, and avoid it with severe respiratory conditions like sleep apnoea. Elderly users and people with liver or kidney impairment metabolise it more slowly and need medical supervision and possibly longer dose intervals. It is not recommended during pregnancy or breastfeeding. Keep use short-course only.
Store Pain-O-Soma 350mg below 25°C in a cool, dry spot — not a steamy bathroom cabinet — keeping tablets in their original sealed blister until the moment you take them, and always out of reach of children. Authenticity checks for this product: the foil blister should be uniformly sealed with no signs of tampering, the batch number and expiry date must be printed on the blister as well as the outer carton, the box should arrive undamaged, and the manufacturer's leaflet should be inside. Discard any tablet that is broken, discoloured or smells unusual, and never use tablets past their expiry date.
Pain-O-Soma 350mg comes in a 20-tablet pack at €58, or €2.90 per tablet. That sits slightly above the equivalent Prosoma 350 pack, reflecting the Pain-O-Soma brand's wider recognition — the active ingredient and strength are the same, so the choice between them is largely brand preference. Twenty tablets covers a standard short course, which is exactly how carisoprodol should be used, so the pack size matches responsible treatment rather than encouraging stockpiling. Orders over €110 qualify for free delivery, making a combined basket the most cost-effective way to order. We keep pricing transparent and never overclaim on savings.
General information about the active ingredient in Pain-O-Soma 350mg — Carisoprodol Tablets.
See the full Carisoprodol guide & all Carisoprodol productsCarisoprodol is a centrally acting skeletal muscle relaxant, marketed under brand names such as Pain-O-Soma and Prosoma. It is used as a short-term adjunct to rest, physiotherapy and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions. It is intended only for brief courses of treatment and is not suitable for managing long-term or chronic muscle pain.
Carisoprodol does not act directly on skeletal muscle. Instead, it works within the central nervous system, where it is thought to alter activity between neurons in the spinal cord and brain, producing a sedative effect and reducing the perception of muscle discomfort. In the body it is partly metabolised to meprobamate, a compound with sedative properties, which contributes to its effects and to its potential for dependence.
Take carisoprodol exactly as prescribed and follow the dosing instructions in the patient information leaflet. It is usually taken by mouth and is intended only for short-term use, typically no longer than two to three weeks, because evidence of benefit beyond this period is limited and risks increase with prolonged use. Do not take more than prescribed, and do not stop a prolonged course suddenly without medical advice.
Common (usually mild and temporary):
Stop and seek medical help if you experience:
Store in the original packaging at room temperature, away from excess heat, moisture and direct light, out of the sight and reach of children. Do not use after the expiry date, and dispose of unused medicine safely through a pharmacy.
No. Carisoprodol is intended only for short-term use, generally no more than two to three weeks. For ongoing or chronic muscle problems, speak to your doctor about more suitable approaches.
No. Alcohol can greatly increase the sedative effects, leading to severe drowsiness, impaired coordination and breathing problems. Avoid alcohol entirely during treatment.
Yes, particularly with prolonged use or higher-than-prescribed doses, partly because it is metabolised to meprobamate. Take it only as prescribed, and ask your doctor before stopping a long course.
Important: This information is general and not a substitute for medical advice. Always read the patient information leaflet supplied with your medicine and consult a doctor or pharmacist before use — especially if you have existing health conditions or take other medication.

Yes. Every order ships in plain, unbranded outer packaging — nothing on the outside indicates the contents or the pharmacy.
Pain-O-Soma 350mg contains carisoprodol, a muscle relaxant used for short-term relief of acute, painful muscle spasm — typically from back strain, neck injury, or overexertion. It works alongside rest and physiotherapy rather than replacing them, and courses are limited to a few weeks per the patient leaflet.
Effectively yes. Both contain 350mg of carisoprodol and work identically; they are simply made by different manufacturers. Choosing between them is a matter of brand preference and price — on Kam4eu, Prosoma 350 is currently the cheaper of the two at €52 versus €58 for 20 tablets.
No. Carisoprodol is designed for short courses — generally no more than two to three weeks — because long-term use significantly raises the risk of tolerance and dependence. If muscle pain persists beyond a short course, the right step is a medical review to find the cause, not continued tablets.
Carisoprodol is a controlled or prescription-only medicine in many countries, including much of Europe and the United States, because of its dependence potential. Rules vary by country, so check your local regulations. Regardless of legal status where you live, treat it as a prescription-strength medicine and involve your doctor.
The leaflet lists drowsiness, dizziness, and headache as the most common effects. Some people experience nausea or a drop in coordination. Sedation is strongest in the first hours after a dose, so avoid driving or machinery until you know your response. Seek medical help for rash, swelling, or breathing difficulty.
No. Carisoprodol and alcohol both slow the central nervous system, and the combination can cause severe drowsiness, falls and dangerously suppressed breathing. Because the active metabolite remains in the body for many hours, skip alcohol for your whole course, not just around each dose.
Either works. Food does not significantly reduce absorption, and taking the tablet with a small meal can ease nausea if you are prone to it. Swallow it whole with water, and try to keep your timing consistent — typically with the last dose at bedtime.
Give it a fair trial alongside rest and gentle movement — muscle relaxants work best as part of overall recovery, not alone. Do not double up doses. If several days at 350mg bring no relief, discuss the 500mg strength or an alternative approach with a doctor rather than self-escalating.
The parent drug clears within hours, but its metabolite meprobamate has a half-life of around ten hours, so mild sedation can carry into the next morning. Urine tests can typically detect carisoprodol for two to four days after the final dose, longer with sustained use.
Yes — the expiry date is printed on the blister and box, and expired tablets should not be taken. Since carisoprodol is a short-course medicine, dispose of any leftover tablets through a pharmacy take-back scheme rather than storing them, flushing them, or binning them at home.
