What does “G/W” mean here, and is this an adult or child? Please share symptoms, vital signs, pregnancy status, comorbidities, and whether they can take oral fluids.

Do not give an IV medication or fluid based only on “G/W.” If there is hypotension, altered consciousness, severe dehydration, chest pain, breathlessness, active bleeding, or persistent vomiting, send for urgent in-person assessment.

For general weakness alone, do not start IV fluids or an IV drug blindly. Check first:

If the person is alert, drinking, and not dehydrated, give oral fluids/ORS and arrange clinical assessment with tests such as CBC, glucose, electrolytes, renal function, and urine examination.

If there is clear dehydration or low BP and they cannot drink, IV fluid needs clinician-directed prescribing, commonly an isotonic crystalloid such as 0.9% saline, with careful reassessment. Avoid empiric large fluid volumes in older adults or anyone with heart failure, kidney disease, or liver disease because fluid overload can be harmful.

Urgent referral/emergency care now for confusion/fainting, BP low, very fast pulse, low urine output, fever with deterioration, severe vomiting/diarrhea, black/bloody stool, chest pain, breathlessness, new one-sided weakness, slurred speech, or glucose <70 mg/dL (3.9 mmol/L). IV fluids are intended for true volume loss or circulatory compromise, not unexplained fatigue alone, as reflected in NICE IV fluid guidance.

For general weakness only, give no IV medicine or IV drip just because the patient requests it.

Send urgently for assessment if BP <100 systolic, pulse >90 with dizziness, fainting, confusion, low urine, fever, vomiting/diarrhea, bleeding, chest pain, breathing difficulty, or focal weakness. IV fluids require reassessment because excess can cause edema and breathing problems, especially in heart or kidney disease, consistent with NICE adult IV-fluid guidance.

Please provide age, BP, pulse, blood glucose, symptoms, oral intake, vomiting/diarrhea, and heart/kidney disease before deciding.
