Botox wears off in 2 weeks, advice?

If the Botox is ineffective, there are several possibilities, looking at all three factors involved: the botox, the provider, and the patient. The botox, may be weak, diluted or old. The provider may have injected improperly or inadequate amounts, trying to stay within a specific budget.  But most commonly, the patient may not be the ideal candidate for the treatment chosen and perhaps he/she should consider more invasive maneuvers. If one's deep frown lines and lifting are no longer able to be accomplished by injectables (filler and/or botox) , the patient may likely need to consider facial surgery.

This isn't typical. Botox results resolve in 3-4 months. Additional Botox may be needed or a combination of Botox with fillers, lasers and microneedling/prp may give the most improvement. Best, Dr. Emer

This is not normal. Botox and Dysport results last 3-4 months on average. Dosing is important and up to a certain point, a higher dose will give a longer lasting result. But 2 weeks is just too short. I recommend you get an in person evaluation with another injector.
