first increase your height then take medicine for weight gain.
here are some tips to how to increase your height after 18+.
First and the most common is to exercise and do morning walk. This makes you grow well.
2 Eat as much breakfast as you can up to fill. This makes your metabolism* strong. Try to eat less meal but after every 2-3 hours.
3) The most important point is to sleep well. It is the dark or night time that matters for your growth. As muscles grow in dark only. Try to sleep in absolute dark or least light to make your muscles relax and they will grow well.
4) Try to keep your head and neck as much straight as possible. Your spinal cord will suppress your height increase if you bow your head most of the time.
5) Never do immoral acts as this suppresses your primary growth(increase of height, muscles etc) and initiate your secondary growth (puberty).

General Exercise – You don’t have to join a gym to be able to exercise. Simply doing some basic aerobic exercises like jumping jacks at home will suffice. Even walking or biking home from work instead of commuting will help you burn fat, and provide a natural way to increase your height.
Advanced Training Regimens – People who feel more dedicated to the cause of fitness may choose to join a gym, or make one at home. Weight training can strain the muscles and bones just enough for you to get a slight yet natural height increase; just be sure not to overdo it to avoid injury.
Stretching – A variety of stretching techniques are also widely believed to give you an increase in height. Taking time every day to stretch out your body, or just remembering to after sitting down for a long time, will benefit your body, health and height to great lengths.
