Your symptoms are most likely from side effects of ELAVIL, though Paxil can also cause dizziness. You may need to consult your doctor if there is any need to adjust your dosage.
Be reminded that alcohol use while on PAXIL and ELAVIL can intensify the dizziness so just in case, you need to avoid or minimize alcoholic drinks. Grapefruit juice may also have some effects while on elavil, so be careful.
Side effects do not necessarily need to appear at the time when you just start taking the medicine. Side effects can take place at any time later depending on different factors such as its blood level and what effects it has done so far.
