Ay, that's such a worry, mama! Honestly, primary complex is something na kailangan talaga ng proper monitoring from your pedia kasi it really depends sa severity at how well he responds sa treatment, a few of us mums have kids who completed their meds and they're doing fine, pero each case is different. Once he finishes his medicines, mag-follow up kayo regularly with his doctor para ma-monitor ang progress, at they'll be the best ones to recommend specific vitamins or supplements na safe at helpful para sa kanya based sa his condition. Sending you strength, alam ko stressful ito!
