If you mean hyperthyroidism, only a doctor can prescibe it after testing you to see if that is what you have. Basically it acts as a control for your thyroid gland, (which is located in the front of your throat). Hyper means it over works, making you lose weight or not be able to put it on and hypo means it under works, making you put weight on and it's hard to lose.
If you mean the birth control pill, it's not going to start your periods but it has been known to have the side effect of putting a little weight. If you are not sexually active, I would not really recommend this as a method of gaining weight as it is not a good idea to take this pill for long periods of time. (Excuse the pun)!
If you mean some other type of pill, I'm not sure which you mean, so cannot advise, sorry. It's not a good idea to take any medication without running it past a doctor first, as there could be side effects that he would need to warn you about. Also, if your doctor knows what you are taking and then has to prescribe another medication, he does it with the knowledge of knowing what can be used together without making you very ill.
