Pharmacist exposes ‘exactly what happens’ to anyone taking sertraline

Pharmacist exposes ‘exactly what happens’ to anyone taking sertraline Raj Patel explains how the antidepressant works, why side effects can appear early and when people may notice a difference People taking a widely prescribed antidepressant may notice physical changes before they feel any improvement in their mood, according to a pharmacist with a massive platform online. Raj Patel, known as the Straight-Talking Pharmacist on TikTok, has outlined what happens when people take sertraline and why its effects may take time to become noticeable. Mr Patel, who has more than 100,000 followers and millions of likes, says the medicine affects how the brain handles serotonin, a chemical messenger linked to mood. He explained: "Sertraline changes how one of your brain's chemical messages is recycled. That message is serotonin." Sertraline belongs to a group of antidepressants called selective serotonin reuptake inhibitors, or SSRIs, which work by increasing serotonin activity in the brain. Mr Patel explained the process in simple terms, saying: "Normally your brain releases it, then recycles it. Sertraline slows that recycling, so that message stays around much longer.” One of the key points in his video is that the medicine's action begins before its full therapeutic effects may be felt: "This happens quickly, when you may actually need several weeks to notice a real difference. Your brain needs time to adjust." NHS guidance says people may begin to notice improvements within around four weeks, although antidepressants can take longer to work fully. The speed and extent of improvement vary between individuals, and doctors usually review patients after starting treatment to assess their symptoms and any side effects. Some people may experience nausea or diarrhoea before noticing a change in their mental health, as these are recognised side effects of sertraline. Mr Patel continued: "Serotonin also works in your gut. That helps explain why nausea or diarrhoea can sometimes appear before you actually get a real benefit." He encouraged people to look for small changes rather than expecting a sudden transformation. “Don't wait for a lightning bolt moment. Look for small changes in how you sleep, cope and manage your day,” he said. Anyone experiencing side effects that are difficult to manage or do not settle should speak to their doctor or pharmacist, rather than stopping the medicine themselves. NHS advice warns that suddenly stopping sertraline can cause withdrawal symptoms, and treatment changes should be discussed with the prescriber.
