Hello gangadhar.anugandula, greetings fromhealthcaremagic.com I am Dr Sourav Chakraborty and i will be helping you with your query Going by you case history the current symptoms you are suffering from like dizziness , sleepy, body pains, shaky body feelings, heavy weight in head, constipation , reduced appetite can be attributed to the intake of the medicine Duzela or duloxetine , but suddenly stopping it can cause seizures so please go visit your physician at the earliest , as i believe the dosage for you need to be revised. The medication by the name Nexito forte or escitalopram is known to cause rarely such similar symptoms . Nausea, diarrhoea, increased sweating, insomnia, ejaculation disorder, postural hypotension, sinusitis, taste disturbances, appetite disorder are the other adverse reactions to look out for . some people have suffered from side effects from this drug but with adequate dose adjustments it has given promising response too, please visit your doctor regularly . Hope i have been lucid in my approach. Take care.
